Germany

Basics
There are now only three network operators left in Germany:

E-Plus was acquired by Telefónica, owner of o2, in 2014 to join and become one single network. So far Telefónica merged both networks either by national roaming between them or by network integration of E-Plus into o2. Both networks are planned to be fully merged and all of E-Plus switched off or over in 2017.
 * Deutsche Telekom (formerly known as T-Mobile)
 * Vodafone
 * o2 (owned by Telefónica) currently merging with E-Plus (acquired by Telefónica) - see below:

All other offers mentioned below are MVNOs of one of the three network operators above. MVNOs are particularly popular for prepaid in Germany and are mostly cheaper than the MNOs. They now have a market share of more than 40% for prepaid which is amongst the highest in the world.

The following operators are sorted according to network. In 2016 all three network operators are neck and neck: Telefónica/o2 is market leader by customer numbers, but Telekom is still ahead what sales figures are concerned. That's why this list follows the historical order of the networks usually used in the country: 1.Telecom, 2.Vodafone and 3.o2(Telefónica).

Coverage and speed
2G and 3G: GSM up to EDGE speed is on 900 and 1800 MHz, 3G is on 2100 MHz like in most of Europe. Almost the entire country is covered by 2G. 3G/UMTS up to DC-HSDPA+ speed is available in most of the populated areas with some blank patches left in the countryside.

4G/LTE: LTE has been rolled out on most common 4G frequencies in Europe on all operators: 800 MHz (band 20), 1800 MHz (band 3) and 2600 MHz (band 7).
 * Telekom coverage : LTE available at 90%
 * Vodafone coverage : LTE available at 84%
 * Combined o2 coverage with E-Plus integrated: LTE available at 75%

Availability
The most convenient way to purchase a SIM card for a visitor is to go to one of the big supermarket, drugstore, service station or electronic market chains and look for the providers described below. MVNOs tend to be generally cheaper than their MNOs:
 * on Telekom: congstar, Lebara mobile, ja!mobil, Penny Mobil and more


 * on Vodafone: Otelo, Fyve, EDEKA mobil, Lycamobile, LIDL Connect and more


 * on o2 (and former E-Plus): ALDI Talk, Blauworld, NettoKOM, Ortel mobile, WhatsApp SIM, AyYildiz, FONIC, NetzClub and more

Most SIM cards can also be used for phone calls and text messages. Data-only SIMs are rare in Germany. The standard voice rate is around 9 ct per minute for a domestic call (to mobile or landline) and about 9 ct for a domestic SMS.

Activation and registration
By law, all SIM cards need to be registered first to be activated. Registration is not often done in shops but online or by phone. But this may pose a problem: Remember, you don't have a working phone or internet access yet! Additionally, there are still few open WiFis in the country. Phone activation can be tricky too, because of the language. Online registration is usually in German only, but possible with the help of an online translator. Look for the words registrieren or freischalten on their website and keep phone and SIM numbers ready.

Foreign addresses are usually not accepted, so use any German address instead, as your personal data will mostly not be verified. But you need to give a valid German street address: name + street name + house number + postal code + city. If you do not have a German address, use your name with c/o name and address of someone else, e.g. the hotel you'll stay. Registration can take some minutes up to a few hours, until your SIM card finally connects with the network. You may need to switch off and on your device to connect.

Update 2016: Right now, only two operators Fonic and Lidl Connect are verifiying your given address by sending you a letter. If you want to use your SIM card for longer and have given an address where you can't be verfied choose another provider instead.

The government plans to change this validation process as online registrations have led to many fake SIM accounts. A new registration scheme with showing an ID card or passport is intended, but not yet finally implemented. So be prepared to show your documents at the point of purchase in the future.

Tethering and VoIP
Tethering is usually allowed with all the shown offers below, except the free ad-sponsored SIM of Netzclub and Lycamobile. Some providers don't supply a profile for the iPhone, but don't block it otherwise. VoIP calls are officially allowed only by o2 and some of its MVNOs. Other operators like Vodafone still officially ban them in their T&Cs without any real consequences. Only Telekom (and thus its MVNOs) has actively blocked and scrambled VoIP in the past, but opened some tariffs for it now.

Topping up
German SIM cards can be topped up in many ways, but only few of them are suitable for visitors as some of them require German bank accounts or German-issued credit cards.
 * when you are in Germany only:
 * Buy top-up vouchers called Ladebons in many stores with a PIN to enter. The vouchers of the network operators are most widely available. You can use Telekom vouchers for Congstar and ja!/Penny mobil, Vodafone vouchers for Otelo, Fyve, Edeka and new LIDL Connect; E-Plus vouchers for Aldi, Ortel, Whatsapp, ay yildiz, Blauworld and NettoKOM and o2 vouchers for Loop and Netzclub. For Fonic, Lycamobile and Lebara, you need special vouchers which are less widely distributed. Note that the billing systems of E-Plus and o2 are not merged yet.
 * Go to one of the three drugstore chains (Rossmann, Müller, dm) or to cash and carry markets like "real" to top up most brands and pay at the cash register with MasterCard, VISA and even AmEx.


 * When you are in or out of Germany (trying to keep an existing SIM card alive, topping up before arrival from abroad or while on roaming):
 * You can top-up with most international credit cards (VISA, MasterCard) on the websites of most providers. But some foreign credit cards may be rejected.
 * The website/app prelado.de does recharges without fees. Again, it might be picky about credit cards from out of the country, but accepts PayPal if you have a positive balance on your account.
 * As a last resort international top-up agencies can do the transaction for a variable surcharge.

EU roaming charges
For roaming in other EU countries the operators charge very different rates. Vodafone and most of its MVNOs let you use your included bundle volumes without surcharges abroad, Telekom charges you 5ct/MB while o2/E-Plus still excessive 23ct/MB. So for roaming abroad in another EU country, it's best to use Vodafone or their resellers otelo, Fyve, Edeka or Lidl Connect and others.

Which network (and operator) to choose:
Deutsche Telekom (formerly T-Mobile): The former market leader has still the best network, what coverage and speed is concerned. This comes at the highest prices of all 3 operators. 4G/LTE is only available on Telekom's own offers. Its resellers (MVNOs) only market speeds up to 3G so far and in some tariffs VoIP is still blocked and scrambled. Vodafone: They have a good coverage throughout the country, not fully on par with Telekom given out at lower prices. Like its competitor 4G/LTE is only on its own brand. All resellers stay on speeds up to 3G for now. It has the cheapest roaming offer for all EU countries (excluding Switzerland) right now selling EU voice, text and data allowances at domestic rates in packages. o2 (with E-Plus): The newly consolidated o2 network and new market leader has a good coverage and 3G speeds in towns and cities, but can't match overall coverage in the countryside for now. 4G/LTE is open on o2's own brand and on some resellers too like AldiTalk making it the cheapest offer on LTE in the country right now. It's the only network that covers the Berliner U-Bahn (metro, underground, subway) in full length by 3G and 4G/LTE.

UPDATE 2016: The old E-Plus LTE network on 1800 MHz has been switched off in June 2016 and all LTE traffic is now routed through o2's own LTE network mainly on 800 and 2600 MHz. This has led to congestion and slow speeds even below 3G rates in major city centers in summer 2016. So if you experience slow 4G speeds, switch to 3G instead to get faster access. So choose: ==== Basic choices ====You have the choice between the network operator and one of its many resellers (MVNOs). The operator gives better support and offers LTE at higher prices, while many resellers give better rates, but often stay on 3G with a minimal customer support.
 * Telekom for the best coverage and speeds at the highest prices
 * Vodafone for the cheapest roaming if you want to use it elsewhere in the EU
 * o2 (incl. E-Plus) for the cheapest domestic rates on LTE or Berlin public transport

To obtain a good deal, data packages must be booked on the SIM card after activation. As weekly rates are hard to find, there is basically the choice of: Take care that the default rate is often charged very high at around 20-30 ct per MB while data in packages are between 0.3-2 ct/MB. So buy packages right from the start, shut off data before the purchase and enable only when this has been confirmed (see here).
 * daily packages for short-time heavy users (available from 500 MB to 1 GB per day)
 * monthly packages for other users (available from 100 MB to 10 GB per month)

More information
The following list shows only the most important players on the German prepaid market. Many other providers compete for special segments and audiences. The German prepaid-WIKI has an updated extended survey (in German only, use Google Translate): www.prepaid-wiki.de.

Deutsche Telekom (formely T-Mobile)
Deutsche Telekom is the previously state-owned, incumbent provider. It's still the biggest telecommunication company in Germany with the best network. For a time it was called T-Mobile like in the US, but has reverted to its old name in Germany. While it caters mostly for postpaid, it still offers prepaid that used to be called Xtra Cards. Note that their rates are the highest in the country and are sold often cheaper by its subsidiary Congstar and MVNOs, not to mention its competitors. In 2015 they opened all prepaid products for 4G/LTE.

Availability
The magenta-coloured Xtra Cards used to be sold all over the country. In September 2015 they changed name and portfolio. They can be ordered online and sent to a German postal address, in their stores called 'Telekom shop' (locator) and many other kiosks, service stations, electronic market chains, post offices and other outlets. Basically, they now offer two product lines for prepaid: While the new voice & data card is available all over from September 2015, you may have to look for their data-only card either online or at Telekom shops. Both starter packs are for 9.95 € including 10 € credit and come in all three sizes. SIM cards can be activated in Telekom Shops or online on their website and can't be switched between the lines.
 * the MagentaMobil Start for voice, text and data
 * the Data Start for data-only

Recharges called "Xtra Cash" are sold in most supermarkets, kiosks, service stations and even at ticket machines all over the country. Minimum amount for top-up is 15 €. SIM cards and their credit stay active for 2 years after the last top-up which gives them the longest validity in the market.

MagentaMobil Start (voice, text and data)
Their new voice and data SIM card has been opened for 4G/LTE. It comes with a monthly base rate of 2.95 € and includes free unlimited voice and text within the same network and to one domestic landline number. For data you can change among these tariffs below in up to 50 Mbit/s on 4G/LTE: Packages renew themselves and can be booked online on http://pass.telekom.de or by calling customer service at 2202 (for free). Beyond the included data volume, your speed will be throttled to 64 kBits/s. Or you can add one of their SpeedOn packs for extra spreed for 31 days: XS with 100 MB at 1.95 € only for Data Start S, S with 250 MB at 4.95 €, M with 500 MB at 7.95 € and L with 750 MB at 9.95 only for Start M and L.
 * Xtra Handy DayFlat: this is their pre-enabled default rate. 0.99 € for only 25 MB within 24 hours. Then speed will be throttled to 64 Kbit/s or you can buy another package for the same price.
 * Data Start S: 100 MB for 30 days: 2 €
 * Data Start M: 500 MB for 30 days: 7 €
 * Data Start L: 1 GB for 30 days: 14 €

Data Start (data-only)
Their new data-only product is aimed at modems, tablets and routers. It doesn't contain text or voice and can't be switched from a voice SIM card. It has been opened to 4G/LTE up to 50 Mbit/s. When you insert the SIM in your device, http://pass.telekom.de appears and you can choose one of their three data options: Packages don't auto-renew. Data will be throttled to 64 kbps, when having used all volume. But you can buy a new package on their website anytime. That's where you can check your data consumption too.
 * Flat S: 500 MB in 24 hours: 2.95 €
 * Flat M: 750 MB in 7 days: 9.95 €
 * Flat L: 1 GB in 30 days: 14.95 €

congstar
Congstar is a subsidiary of Deutsche Telekom and a cheaper alternative to access the Telekom network, but remains still more expensive than most of its competitors. They stay on 2G and 3G only so far, no 4G/LTE yet.

Availability
The new starters are labeled with "prepaid wie ich will" = prepaid the way I want it. Try to get a starter pack with no plan pre-enabled. The ones with a plan require a Germany bank account and are called Surf Mix or Smart Mix. Mini, micro and nano SIMs are available

They can be ordered online to be sent to a German postal address. Offline, starters are available at the shops of Deutsche Telekom, some outlets of the drugstore chains of Rossmann, dm and Müller, the supermarkets of extra, real, Kaufland, Netto, Penny and many service stations and kiosks. Be aware that some of these stores may not have Congstar products in stock.

The starter pack costs 9.99 € with mini/micro or nano SIM and 10 € preloaded (= 5 € from the start, another 5 € after activation). For registration, you need to go online and use Google Translate.

Congstar prepaid cards can be topped up with their own vouchers bought in the shops named above or any prepaid voucher of Deutsche Telekom for Xtra Cards even more widely available. To check your balance dial *100#.

Default Data Rate
There is no data from the start. The first time you connect to the net, you will be directed to http://datapass.de, where you can set your plan. Two default rates are offered:
 * messaging option for free: Max. 32 Kbit/s (both downstream and upstream), up to 1 GB per month, then further throttled to 2 Kbit/s.
 * Surf Tagesflat = day "flat" for 0.99 €: for 24 hrs at 7.2/1.4 Mbit/s, throttled beyond already 25 MB to 64/16 Kbit/s, but no charge if you don't use data on any given day.

Data Feature Packs
Online on your personal account or the datapass.de site, you can customize with a monthly data package:
 * 100 MB: 2 €
 * 300 MB: 4 €
 * 500 MB: 8 €

These bundles have a max speed of 7.2 Mbit/s. All three bundles can be doubled in volume to 200, 600 or 1000 MB and in speed from to 14.2 Mbit/s by adding a Datenturbo add-on for 5 € per month.

After depleting the data quota, speeds are reduced to 64 Kbit/s downlink and 16 Kbits/s uplink. But you can upsize even several times per month: the 100/200 MB bundle with another 100 MB, the 300/600 MB bundle with another 200 MB and the 500/1000 MB bundle with another 300 MB for 4.90 € each with the Speed on add-on.

All regular packages auto-renew if not cancelled or changed before in your personal account.

Internet Stick / Surf Card
Alternatively, congstar sells USB dongles (= internet sticks) with an own tariff line and the same tariff without hardware as Surf Card. It can be used in phones too and also has voice. It's sold online or at the stores named above, but is often hard to find, especially without a modem.

The USB stick is a SIM-locked ZTE MF190 and sold with the SIM for 29.90 € including 10 € credit. The SIM-only "Surf Card" for 9.90 € with 5 € included. This tariff can not be changed to a regular line.

Default rate is a 24 hour daily rate for 2.49 € and 500 MB included. Beyond this quota, speed will be throttled form 7.2 Mbit/s to 16 kbit/s. You can add two monthly packages:
 * 1 GB: 12.90 €
 * 3 GB: 19.90 €

Settings
APN: internet.t-mobile

VoIP (Skype, WhatsApp calls...)
Congstar has a strange dual policy about VoIP. On its voice tariffs with data packages it still actively blocks communications with OTT apps like Skype. If you plan to use VoIP services, you can only make it work using a VPN app like Cyberghost.

In contrast to that, on all data-only plans like the surf card packages VoIP is now officially supported and proved to be working.

Vodafone
Vodafone has opened 4G/LTE on its own prepaid offers (but not its MVNOs) with speeds up to 250 Mbit/s. They cover 90% by 4G/LTE in 2016. As with all MNOs in Germany, their offers are higher priced than their MVNOs, but they may give you a better service, 4G/LTE and have more service and top-up points.

EU roaming offer
In May 2016 Vodafone opened most of its prepaid plans for EU roaming without surcharges. This means that you can take any Vodafone plan or those of its MVNOs and use the included or added allowances for roaming at domestic German rates. This is by far the cheapest roaming solution for Europe in Germany right now. Note that Vodafone's Websessions, otelo's surf plans and all offers of Lycamobile are not included.

Availability
Their prepaid card is called "CallYa" and is available at their stores (store locator) and many more outlets for free without credit, 9.95 € with 10 € credit or 14.95 € with 15 € credit. If you have a German mail address (or know someone who has), you can order online and have a "Freikarte" (= free SIM without credit) sent to you by mail for free that is already activated. Thus, you can skip registration process.

Recharge vouchers are for sale all over the country in supermarkets, service stations and kiosks amongst others starting at 15 €. To check balance, dial *100#.

Data feature packs
Voice plans with data for 4 weeks (= 28 days):

Another solution is to book additional 250 MB for one-time usage, valid for 7 days. You can book this option multiple times, it's non-repeating and it can be added at any time, even if you still have enough data volume: Again, the included allowances of all CallYa plans and top-ups can be used without surcharges in all over the EU/EEA for roaming, mostly on 4G/LTE Vodafone and partner networks.

You need to buy a special SIM card "WebSessions Freikarte" either online for free. Or get it in an Vodafone store (locator see above). They may be harder to find than regular Call ya SIM cards. These data SIM cards can be topped up online by credit card or using regular Vodafone top up vouchers available everywhere. The vouchers can be redeemed through a link on the WebSessions start page.

If you use a non-Vodafone USB dongle, you need to download Vodafone's Mobile Broadband Software to your computer and choose WebSessions as tariff. The first time you connect to the internet, you will be redirected to the WebSession start-up page where you can choose a package: All packages are valid for up to 30 days or until used up.

o2 (Loop, and former E-Plus)
o2, owned by Telefónica, has now grown from Germany's smallest network to its biggest after the merger with E-Plus, what number of subscribers is concerned. The shops of E-Plus/Base have been rebranded and each customers can use also the both 2G and 3G networks nationwide and 4G/LTE. This gives a better coverage in the countryside, but still not as widespread as Telekom or Vodafone. 4G/LTE has been opened for prepaid in 2016 on its own brand and some of their MVNOs.

Like all network providers in Germany o2 charges higher rates than its resellers. The reason to add the MNO is the opening of their 4G/LTE network to new prepaid customers in February 2016. o2's own prepaid product is called Loop, but you can get their 4G/LTE now on some resellers much cheaper.

Maximum Transfer Speed
2G up to EDGE, 3G up to HSDPA and 4G/LTE up to 21.6 Mbps. You should have 800 MHz (band 20) for LTE as o2 uses it mostly.

Availability
o2 likes to call its starter packs Freikarte (= free card) because they are mathematically sold for free: Loop starter packs are sold online (to be sent to a German postal address), in o2-branded shops (locator), in many service stations, postal offices, supermarkets, electronic chain stores and kiosks.
 * for free ('Freikarte '): without credit, only sold online and sent to a German postal address. If you have a German mail address (or know someone who has), you can get the SIM for free, that is already activated. Thus, you can skip registration process.
 * 6.99 €: with Loop Smart S (see below) pre-booked
 * 9.99 €: with Loop Smart M (see below) pre-booked
 * 14.99 €: with Loop Smart L (see below) pre-booked

Top-up vouchers can be found there and many other places too for 15, 20 or 30 €. To add value, type *103* #. Alternatively, you can use a bank transfer, their app or a top-up agency like prelado. SIM card and credit stays valid for 6 months after the last recharge. Check balance by *101# and validity by *102#.

Activation
Their SIM needs to be registered and activated before use. This is done online on their website or by calling 0800 800 2002 (for free from another phone) and takes some minutes or hours to take effect.

SIM sizes
A triple size SIM card in mini, micro and nano is given out.

Default data rate
Default rate outside packages on all tariffs is the "day flat" of 0.99 € per calendar day with up to 30 MB high speed data (up to 21.6 Mbps and 4G/LTE), beyond throttled to 32 kbps.

Data feature packages
These monthly bundles are offered for data in up to 21.6 Mbps and 4G/LTE: While Smart S-L contains unlimited calls to o2, the Smart All-In has unlimited calls and texts in all domestic networks. On all bundles unused data rolls over to the next month. From 29/3/2016 all newly activated SIM cards include the very disputed "Datenautomatik": Having used up all data volume in M or L tariffs o2 automatically adds up to 3 "Datensnacks" ("data snacks") of 100 MB for 2 € each, in XL 250 MB for 3 € each. Only after the 3 added "snacks" (or all balance) are used up too, speed will be throttled to 32 kbps.
 * Smart S: 50 MB and 50 mins or SMS: 6.99 €
 * Smart M: 750 MB and 200 mins or SMS: 9.99 €
 * Smart L: 1 GB and 200 mins or SMS: 14.99 €
 * Smart XL: 1 GB 1.5 GB and 200 mins or SMS: 19.99 €
 * Smart All-In: 500 MB: 29.99 €; 2 GB: 39.99 €; 5 GB: 49.99 €

Data-only SIM - o2 go
This SIM has only data, no voice and is aimed at tablets and modems. It is sold in a seperate starter pack called o2 go prepaid for 9.99 € with 500 MB valid for 6 months after activation. These packages can be booked for more data on up to 4G/LTE: Activation is online through your o2 account. Having used up data quota, speed will be throttled to 64 Kbps.

Maximum Transfer Speed
2G up to EDGE, 3G up to HSDPA and 4G/LTE up to 21.6 Mbps. FONIC uses the network of combined network of E-Plus/o2, which has a fair coverage and gives good performance in the cities.

Default data rate
High € 0.24 per MB (in 100 KB units).

Data feature packs

 * Daily Flat = Tagesflat (per calendar day = 0:00h - 23:59h) = 1.99 € (after 500 MB per day, speed drops to 32 kbit/s). There is a price cap of 20 € per month, so if you use it for 10 days, the remaining days are free. For subscription text START TAGESFLAT to 36 642 (free). The fine print says that after 5 GB per month, the speed also drops to 32 kbps.
 * monthly rates for 30 days:

To activate, text code to 36642 for free. You will receive a confirmation SMS and you need to reply JA to that to confirm. This will be confirmed again, then another SMS that your request is being processed, finally a confirmation that the option is active along with the end date or a message that you don't have enough credit.

Warning: If you use the internet before getting final confirmation, it will be charged at the standard rate per MB (see above). Staying active, the monthly flat renews automatically if you have sufficient credit and the daily flat will remain your default rate. Text activation code and replace START by STOP to 36642 to prevent them from renewing.

When you have exceeded the data quota in the running time of the package, you'll get a SMS info and speed will be reduced to approx. 32 kbit/s. Then, you will be offered to buy a 'reload code' with 300 MB at 2.49 € or 500 MB at 4.99 € depending on base pack.

Availability
FONIC SIMs are available online for 9.95 € but for registration you need to have a German bank account. Bought offline this is not required. Starterpacks are sold at the drugstore chains of Müller and dm, the cash'n'carry stores of 'real' and the petrol stations of Jet amongst others. Top-up vouchers can be found there, at LIDL supermarkets (see below) and Rossmann. Be aware that o2 vouchers called Loop or Tchibo vouchers can't be used. FONIC SIM cards can be reloaded by bank transfer from abroad too. This may take a few days and is described here (in German).

Activation
The SIM needs to be activated and unlocked before use. First of all you need to register, either over the phone or online (in German). iPhone users should disenable FaceTime to prevent it from sending SMS. It then may take up to a couple of hours for the activation to take effect. You will receive a welcome SMS from FONIC when this has happened. Then you can use the PIN on the back of the FONIC credit-sized card to unlock the SIM. The unlock won't work until the phone number has been activated. If you activate the Fonic Smart S plan for example, you will be stuck with that plan for a month before you can change it!

Fonic is one of the few providers so far to verify given postal adresses by sending a letter there. Better choose another provider, if you can't verified at the given address and want to use your SIM card for longer. It might get suspended.

SIM sizes
SIMs in a starter packs are normally standard size, but with perforations to break out the micro-SIM if required. If you want a nano SIM, you need to buy and register a standard/micro SIM first, then order a new nano-SIM card from here. You will be sent a nano card (to a German address only) with mini and standard adaptors for a surcharge of 10 €, which is inconvenient if you need a nano SIM.

FONIC Mobile (formerly known as LIDL Mobile)
In October 2015 LIDL changed partners. All old LIDL mobile SIM Cards sold until September 2015 in their stores are rebranded into FONIC mobile. The old tariffs have grandfathering and are similar to regular Fonic rates. Top-up vouchers are still sold, but no old Fonic starter packs at Lidl's anymore. From now on you'll have to choose a FONIC top-up voucher, not a LIDL-branded voucher for topping up their old SIM cards. We don't list FONIC Mobile as SIM cards are currently only available online to be sent to a German postal address. To see their rates, check their updated pricelist. The new Lidl offer is now called LIDL Connect (see above) operating on the Vodafone network.

NetzClub


NetzClub is a free ad-sponsored SIM card with a 100 MB high speed volume per month without charge. As a subsidiary of o2, Netzclub uses the combined E-PLus/o2 network, which is still good in performance mainly in the big cities,

Speed
up to 7,2 Mbit/s on 2G and 3G, but no 4G/LTE so far. After reaching 100 MB a throttle is activated at 32 kbit/s (= half GPRS speed).

Availiability
Order and registration are only possible online. The SIM is not sold offline in any stores. The SIM card will be sent to a German address free of any charge within 5 - 7 days. So you must have a German postal address to enjoy the offer. They will only send out one SIM per person and a maximum of 3 SIMs per household (same last name and address). Change the option from bank transfer to top up using vouchers (Aufladung mit o2 Guthabenkarte) during the registration process to order the card without a bank account and without a mandatory first payment.

You have to be willing to accept some ad mails to the given email account and some advertisement SMS will be sent to your number as well. This can amount to 30 SMS or mails per month but is normally much less. You can influence this a bit through the type and number of interests you select in your ad preferences. This is how this service is paid for after all. If you don't want junk ads, consider other offers instead.

SIM sizes
The SIM sent out by mail is a hybrid mini-, micro-, and nano-SIM.

Recharge and upsize
There is no need to have credit to use the free 100 MB data per month. To top up use o2 vouchers called "Loop" from 15 € or Tchibo cashcards from 10 €. To use bank transfer (from 0,01 €), see this site (in German): []

When the 100 MB free data quota is used up you can continue to use the flatrate at a slower speed (32 kBit/s) for free or choose one of these options: Take care, if you choose surfpacks with auto-renewal. This may be a bad deal in the long term: the monthly Surfpack renews every month as long you have enough credit and overrides the free data allowance in the next month. To discontinue you have to call customer service 0176 888 93939 (9c/min) or simply be low on credit to prevent auto-renewal.

EU Roaming package
For data roaming in all EU countries outside of Germany plus Switzerland Netzclub offers two new packages. You don't need to have booked a domestic package before: All roaming packages don't auto-renew and can be renewed anytime as often as you like. Max. speed is officially 1 MBit/s, but in reality often higher on 3G.
 * 50 MB for 24 hours: 1.95 €. For activation text "START EUSURF 50" to 22233
 * 100 MB for 7 days: 4.95 €. For activation text "START EUSURF 100" to 22233

Validity and refund
As long as you receive advertisement mails and SMS' your unused credit has an unlimited validity, which is unique for German pay as you go prepaid cards. If you choose not to use the card anymore you can have the left credit transferred to a German bank account.

Tethering
Tethering and VoIP are not allowed in the T&Cs, but not actively blocked.

€ 0.24 / MB (without package).

Data feature packs

 * Daily package: 24 hours data plan (after 1 GB throttled to GPRS speed): € 1.99. For activation see below. Daily and monthly packs can be mixed.

 * Monthly packages (all valid for 30 days):
 * Activation is online, by ALDI Talk app or dial *121*004# to activate, *123# to check status of activation, *122# to cancel data pack after the present plan expires. If you do not dial this code, ALDI will automatically try to activate a new data plan after expiration of the present one.

Availability
Starter packs are exclusively available in any Aldi Store, Germany's leading discount supermarket chain. They are not on display in the shops. You have to ask at the cash register (check-out) for it.

SIM sizes

Billing for voice and text
ALDI talk charges slightly different call rates than the other providers shown. A domestic call to landlines or mobiles and a domestic SMS is billed with € 0.11/min (instead of 9 ct elsewhere). This doesn't need to be a disadvantage: "Community calls" (meaning Aldi to other Aldi numbers) are charged with 3 cents/min only and all calls are charged from the 2nd minute by the second (60/1) instead of by the minute (60/60) like most other providers do.

Tethering and VoIP
Tethering and VoIP is allowed

EU-Roaming Package
ALDI offers this only add-on for data roaming outside of Germany in all EU countries, Norway and Switzerland. For 500 MB in 7 days 4.99 € are charged. This package can be booked online or by ALDI Talk app. When expired (by volume or time) it doesn't automatically renew, but can be booked again. This can be a good deal for a light roaming data volume or if you need Switzerland included. For more data better check Vodafone (see above) or buy a local SIM in the destination country.

Default rate
In September 2015 they have changed the rules, but old customers have grandfathering. The free allowance is now only 10 MB per month and not specific to WhatsApp anymore. Take care, that the 10 € plan (see below) is set by default and you have to reset it to the free basic allowance before use.
