Greece

Basics
There are three physical network operators (MNOs) in Greece:  All three MNOs have closely attached MVNOs or subsidiaries that resell their offers: Frog Mobile on Cosmote, Tazamobile on Vodafone and Q on Wind. Other MVNOs like Cyta focus on the triple-play market and started to sell SIM cards too.
 * Cosmote
 * Vodafone
 * Wind

2G/GSM is on 900 and 1800 MHz, 3G mainly on 2100 MHz and some 900 MHz. 4G/LTE has started on 1800 MHz and is now on 800 MHz and 2600 MHz too on all three operators.

Cosmote has the best coverage and the best speed, while Wind has the cheapest prices at the lowest coverage nationwide, Vodafone is in between.

Availability You can buy SIM card in official dealer shops and from distributor points. There is no place to buy any SIM card in Athens airport (ATH) - tested March 2017. So it is better to buy it in the city.

In order to purchase the card, you'll be asked for an ID card or a passport, as this is required by law since 2011. Children under the age of 18 can't activate a SIM card on their own.

Be aware, that many shops prefer to sell you more expensive bundles (e.g. with mobile phones or with 3G USB modem sticks) stating they ran out of stock of naked prepaid SIM cards. But where are the bundles, there are the SIM cards too.

With all the three MNO providers you have the choice between a call, text and data SIM card and a data-only SIM with lower data rates but no calls and SMS possible. Each MNO has its own MVNO which only sells one SIM card and doesn't need to be a better deal. MVNOs are harder to find, don't have sales points in the countryside and limited support only. Here is a survey of their products:

Cosmote
Cosmote is the national provider with the most subscribers and the best coverage in 2G, 3G and 4G. 2G/3G Cosmote Coverage. 4G/LTE was launched in 2012 and now covers 85% of population in 2016: 4G Cosmote Coverage. 4G/LTE is given out without surcharge to all customers including prepaid plans. In 2016 it was expanded to over 60 islands in the Saronic, Cyclades, Dodecanese, Ionian, Sporades, North and East Aegean and Crete. Also, most summer destinations in mainland Greece, including Halkidiki, Nafplio and Pelion are now covered by LTE speeds.

Availability
You can buy Cosmote prepaid packages in their official shops (preferred) or from street distributors. There is no place to buy the SIM card in the Athens airport, but their ads are hanging almost everywhere. No kiosks, no gadget shops, no distribution point - you will need to buy it in the city. Central office in Athens located near Syntagma square subway station. Distributors (usually working students) are also often noticed there. You can also buy the SIM cards and connection kits (SIM card + cheap simple mobile phone or USB modem) in their "Germanos" gadget stores (stores list). You will need your passport or ID card to buy their package. You should also sign the terms and conditions agreement. Some people report successful registration with driver license or student ID card. You can also try asking the distributor to sell the SIM card without showing your ID, but this is illegal according the law. Cosmote offers 2 different prepaid packages - "Cosmokarta" and "What's Up".

Both tariff lines have different combined packages, but the same data-only bundles. You can change between the two plans by texting 'ALPAK' to 1314. The first change is free. All subsequent changes cost 3 €.

Recharging and account validity
You can recharge your account online here using PayPal or Visa/MasterCard EU-issued credit cards. Recharging page is only in Greek but the process is straightforward and easy. You can read instructions how to recharge in English here. Minimal recharge amount is 5 €. 12% state telecommunication tax is applied to all top-ups. So if you load 5 €, you'll actually get 4.86 € net worth.

When you recharge online for 30 €, you will get 3 € bonus.

Recharged credits valid for 90 days (3 months) since last recharge. The mobile number and the SIM card is valid for 12 months (1 year) since last top-up. If you don't recharge for 13 months (12+1), your subscription terminates. To save your number it is enough to recharge for 5 € at least once per year.

You can also recharge in Cosmote offices and Germanos stores or buy the top-up voucher.

"What's up" prepaid package Originally started as their youth line, "What's Up" package is a good solution for mobile communications in Greece.Good rates for talking, texting and Internet, good coverage, easy to find, easy to use, easy to recharge and keep the card active (long expiration term).

New SIM cards come universal - triple-cut, standard, micro and nano. No need to cut.

New starter package costs 5 €. It can be empty (without any credits), but there is a promotion with 5 € preloaded. So you can pay only 5 € and get the SIM card with 5 € credits.

When you insert the new SIM card at the first time, it will ask for a PIN code printed on the SIM card plate. Do not forget to disable PIN code check especially if you are planning to use it with modem or router device.

Dial any number to activate your package.

Tazamobile is a MVNO on Vodafone network in 2G and 3G. Be aware that the points of sale to get a SIM card are limited, as you can't obtain a SIM card directly from a Vodafone store.

Wind


Wind is the smallest network provider in Greece, but can give good speeds where available at low rates: Wind 3G Coverage Map. In 2015 4G/LTE started in major parts of Athens and Thessaloniki. It is now available in other parts of the country too: (4G Coverage Maps ). 4G is given out without surcharge to all customers, including prepaid plans.

F2G
F2G (for free to go) is the name of their prepaid talk, text and data line. The connection pack is free, but you have to buy a top-up card for 10, 15, 20 or 30 EUR. Wind gives high bonuses for online top-ups. They can be done by internatl. credit cards and PayPal, if you have registered online before. For every 1st online top-up of 10 EUR or more per calendar month 1 GB of data is added for free.

So it's a better idea to buy the SIM card for 5 EUR including 0.55 EUR credit, 60 domestic mins, 50 domestic texts and 20 MB (valid for 30 days) but without top-up right from the start at their stores: Wind Store Locator. Default or above bundle rate is 1 EUR per 20 MB and day. Two different data packages can be booked on the F2G SIM:
 * Giga Surf: 1 GB for 30 days at 5 EUR, you can later add 500 MB at 2 EUR for 1 day
 * Absolute Surf: 10 GB for 30 days at 15.12 EUR

A Giga Surf bundle can be activated up to 4 times in a month on www.f2g.gr or the F2G app. They also offer Blender with an allowance of 400 domestic mins, 100 dom. text and/or 1 GB data at 8 EUR valid for 30 days. You can mix all three consumptions, but the value of the others will decrease.

Mobile Broadband
Wind also sells their Mobile Broadband without contract data-only SIM card. The connection pack is sold at 18 EUR with a SIM and 3 GB data included for 90 days. Following top-ups are available: These SIM cards can be loaded with Wind top-up cards. To activate a pack, text the 16-digit number to 1268. To check data balance, text free SMS to 1228 with the word "balance". This SIM is for data-only and no SMS, but those two service numbers.
 * 1 GB for 30 days: 5 EUR
 * 5 GB for 30 days: 15 EUR
 * 6 GB for 90 days: 25 EUR

Q
Q is a subsidiary of Wind on their 2G, 3G and 4G/LTE network (for coverage see above).

They give the highest bonuses for top-ups and lowest rates in the country.

Availability
Q starter packs are available for free at some kiosks and most Wind branded stores (store locator) with a scratch card for the top-up value.

You need to register and top-up online using an international credit card or PayPal. They give out a 500 MB bonus for the registration every month (not accumulable). Only one of these additional bonuses are given out for top up of 10 EUR or more for the first top-up only per calendar month:
 * 500 MB and 1000 Q mins: for an online top-up
 * 524 MB: for a top-up more made in a Wind store
 * 500 MB and 1000 Q mins: for a top-up using scratch cards

 * 700 MB per month plus unlimited Whatsapp: 4 EUR

Thus, combining top-up and online bonuses with a data package, very good rates for data can be achieved. Default rate outside packages and bonuses is 1.01 EUR per 20 MB.
