Germany

Basics
There are now four coming down to three network operators in Germany:


 * Telekom Deutschland (formerly known as T-Mobile),


 * Vodafone
 * o2 (owned by Telefónica) now merging with
 * E-plus (acquired by Telefónica) - see below.

Update 3/2015: E-plus was acquired by Telefónica in 2014. In 2015 E-plus and O2 are joining forces to become a united network. Starting 15th of April 2015 Telefónica opens free national roaming in 3G only between their two networks, 2G and 4G/LTE remain still seperate. It's still unclear which of their MVNOs are to be dropped or moved to other carriers. All other offers mentioned below are MVNOs of one of the 3 or 4 network operators above. MVNOs are particulary popular for prepaid in Germany and are mostly cheaper than the MNOs.

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. Deutsche Telekom used to have the best coverage nationwide, followed by Vodafone. Eplus and O2 are joining forces in April 2015 on 3G to challenge the others.


 * Telekom coverage
 * Vodafone coverage
 * O2 coverage
 * e-plus coverage

4G (as of 3/2015): LTE has been rolled out on three different frequency bands so far: 800, 1800 and 2600 MHz.


 * Telekom: on 800 MHz band in the countryside and 1800/2600 MHz in cities, not given out on prepaid yet.
 * Vodafone: on 800 and 2600 MHz, given out for prepaid with a surchage, not on its MVNOs.
 * o2: on 800 and 2600 MHz, not given out for prepaid yet.
 * e-plus: on 1800 MHz in city centers only, given out for prepaid without surcharge on all tariffs and its MVNOs.

Make a network scan, if you want to use it at one particular place and choose the network accordingly. O2 and Eplus LTE networks will stay seperate for the time being.

Availability
The most convenient way to purchase a SIM card for a tourist is to go to one of the big supermarket, drugstore, petrol station or electronic market chains and look for the providers described below. MVNOs are mostly cheaper than MNOs.
 * Telekom: congstar, Lebara mobile, ja!mobil, Penny Mobil


 * Vodafone: Fyve, klarmobil, EDEKA mobil, Lycamobile


 * e-plus/BASE: ALDI Talk (= Medion mobile), Simyo, blau, ortel mobile


 * o2: FONIC, LIDL mobile, NetzClub

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

Survey of MVNOs
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:
 * 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)

Take care that the default rate is often charged very high at around 20-50c/MB while data in packages are between 0.3 and 2c/MB. So buy packages right from the start, shut off data before and enable only when the purchase has been confirmed (see here).

Activation and registration
By law, all SIM cards need to be registered first to be activated. Registration is often not done in the 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 few open Wi-Fis 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.

Mostly foreign addresses are not accepted, so use any German address instead, as your personal data will not be verified. But you need to give a valid German address: postal code + location + street name + house number must be consistent and may be automatically checked in a database. 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.

Tethering and VoIP
Tethering is usually allowed with all the shown offers below, except the free ad-sponsored SIM of Netzclub. Some providers don't supply a profile for the iPhone but don't block it otherwise. VoIP calls are officially allowed only by E-Plus and O2 and some of its MVNOs. Other operators like Vodafone still ban them in their T&Cs without consequences. Only Telekom (and thus its MVNOs) has actively blocked VoIP in the past.

Topping up
German SIM cards can be topped up in many ways, but only few of them are suitable for visitors as the others require German bank accounts or German-issued credit cards.

When you are in Germany: When you are not in Germany (trying to keep an existing SIM card alive or topping up before arrival from abroad):
 * You can buy top-up vouchers locally called Ladebons in many stores with a PIN to enter. The vouchers of the 4 network operators are most widely available. You can use Telekom vouchers for Congstar and ja!/Penny mobil, Vodafone vouchers for Fyve and Edeka, Eplus vouchers for Aldi/Medion, ortel and Simyo and O2 vouchers for Netzclub. Lidl and Fonic vouchers are interchangeable, but not with O2. For blau, Klarmobil, Lycamobile and Lebara, you need special vouchers which are less widely distributed.
 * You can go to one of the three drugstore chains (Rossmann, Müller, dm) or to a "real" cash and carry market to top up most brands and pay at the cash register with Mastercard, VISA and even AmEx.
 * You can top up with most international credit cards on the websites of MVNOs Lebara and Ortel mobile only. Ortel also accepts PayPal and Paysafecards.
 * All other providers can be topped up without any surcharge using PayPal only on the third-party website of e.g. www.prelado.de which can be switched to English. This loophole is also the most convenient way to recharge from abroad to keep a SIM card alive of most brands. Be aware that they don't accept non-German issued credit cards, but only PayPal. Even PayPal may only be accepted, if you have a positive balance on your account.

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.

Their only prepaid offers "Handy-Spar-Tarif" and "Internet Dayflat" with numbers beginning 0152, 0162 and 0174 are on Vodafone network. Actually, the "Internet flat" is the only tariff worth mentioning for prepaid. The other prepaid tariffs are overpriced, but the "Internet flat" gives the cheapest day rate on a Vodafone network for data right now.

Mindblowing €0.49 per MB (in 100 KB units). So don't use data before booking a package.

=O2 network =

Maximum Transfer Speed
2G up to EDGE (220 Kbit/s), 3G up to HSDPA (7,2 Mbit/s). FONIC uses the network of O2 Germany, which is not the best in coverage but gives still good performance in the cities.

Default data rate
€ 0.24 / MB (in 100 kb units).

Data feature packs

 * Day Flat = Tagesflat (per calendar day = 0:00h - 23:59h) = 1.99 € (after 500 MB per day, speed drops to 56 Kbit/s). There is a price cap of 25 € per month, so if you use it for 13 days, the remaining days are free. For subscription text START TAGESFLAT to 36 642 (free).
 * Month Flat = FONIC Classic Internet with 500 MB = 9.95 € - lasts 30 days (after 500 MB, speed drops to 56 Kbit/s). For subscription text START HANDYINTERNET to 36 642 (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. The whole process can take some hours on the o2 net. 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 STOP TAGESFLAT or STOP HANDYINTERNET to 36 642 to prevent them from renewing.

When you have exceeded the data quota in the running time of the package, you get a SMS info and speed will be reduced to approx. 64 kbit/s. Unlike with Lidl mobile, there is no upsize possibility for the package.

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 (see below) and Rossmann. Be aware that the vouchers of FONIC and LIDL are interchangeable, but O2 vouchers called Loop or Tchibo vouchers can't be used. FONIC and LIDL cards can be reloaded by bank transfer from abroad too. This may take a few days and is described here (in German): http://www.prepaid-wiki.de/index.php5?title=%C3%9Cberweisung_FONIC

Activation
The SIM needs to be activated and unlocked before use. First of all you need to register, either over the phone or on the fonic.de website (look for the "Freischalten" link in top right corner). 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 wont work until the phone number has been activated.

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 SIMs, 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 charge of 10 € which is inconvenient if you need a nano SIM.

LIDL mobile


FONIC has developed LIDL mobile to be sold exclusively at the LIDL discounter supermarkets in Germany. They are on display at the cash register / checkout desk. Be sure to buy the Classic line and not the Smart line, as Smarts require a German bank account.

Default data rate
Generally all the FONIC details mentioned above are valid for LIDL too. Here are the major differences:
 * Starter pack costs 9.95 € (sometimes reduced to 4.95 €) with 10 € preloaded.

Data feature packs

 * The daily flat is not a calender day, but real 24 hrs for a 500 MB and 1.99 €.
 * The monthly flat comes in three sizes:
 * Smartphone-Internet-Flatrate S with 150 MB in 30 days for 3.95 €
 * Smartphone-Internet-Flatrate with 500 MB in 30 days for 6.95 €.
 * Both of theses monthly packs can be upsized: another 150 MB in the small pack for 1,49 € texting START LIDL SURFUP 150 and the larger pack with another 500 MB for 4.99 € texting START LIDL SURFUP 500 to 54356 respectively.
 * Monatsflatrate with 5 GB in 30 days and max. 500 MB per calendar day, then reduced to 64 kBit/s and not upsizable for 14.99 €.
 * To activate the packages text START TAGESFLAT for the daily flat, START HANDYSURF 150 for 150 MB, START HANDYSURF for 500 MB and START MONATSFLAT for 5 GB to 54356. Be aware that it may takes some hours until the request is processed and you surf on the default rate in the meantime (see FONIC above).
 * To deactivate change START to STOP in the text messages to 54356.
 * You can buy Lidl as well as Fonic top up vouchers. While Fonic starts at 15€ minimum, at Lidl's you can get 5€ denominations.
 * Like Aldi, Lidl now offers an EU roaming package for cheap data roaming outside Germany in all EU countries, Norway and Switzerland. For 150 MB in 1 week 4.99 EUR are charged. This is one of the cheapest roaming data packs on the German market well below the EU price cap (compare with Aldi offer above). To activate, text "START LIDLEU150MB" to 54356 and wait for confirmation SMS. It doesn't renew itself: when used up by time or volume, it can be booked again. For more volume, better buy a local SIM card in the respective country.

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 O2 Germany's network, which has not the best coverage but is still good in performance mainly in the big cities,

Speed:
up to 7,2 Mbit/s. 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 card will be sent to a German address free of any charge. The SIM is not sold offline in any stores. So you must have a German postal address to enjoy the offer. Furthermore, 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. 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 micro- and mini-SIM. Nano-SIMs can't be ordered with a new subscription but only as a replacement SIM for 10 € extra.

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, Netzclub sends out a SMS offering the "Surf-Pack" giving you 500 MB extra volume per month for 6.95 € (After reaching the 500 MB of the "Surf-Pack" a throttle is activated at 64 kBit/s). For buying this, you have to have credit and subscribe it by texting START SURFPACK to 22233. This may be a bad deal in the long term: the monthly surfpack overrides the free offer in the future and continues every month as long you have enough credit. To discontinue you have to call costumer service 0176 888 93939 (9c/min) or simply be low on credit.

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.

Billing
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 11 cents [min] (instead of 9c elsewhere). This doesn't need to be a disadvantage: "Community calls" (meaning Aldi to other Aldi numbers) are charged with 3 cents per min only and all calls are charged from the 2nd minute by the second (60/1) instead of by the minute (60/60) like other providers do.

Tethering

EU-Roaming Package
ALDI offers this add-on for cheap data roaming outside of Germany in all EU countries, Norway and Switzerland. For 150 MB in 1 week 4.99 € are charged. This package can be booked online or by ALDI Talk app. When expired (by volume or time) it does not automatically renew, but can be booked again. This is one of the cheapest prepaid roaming options in Germany on the market quite below the EU price cap on data (compare to Lidl offer below). For small data volume out of Germany, it can be a valid option. For bigger packages, buy a local SIM card in the respective country instead (see WIKI).
