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.
 * 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 but often the slowest speed, while Wind has the lowest prices, but the lowest coverage. SIM cards are available in shops, and in order to activate it you will be asked for an ID or a Passport, as this is required by law since 2011. Children under the age of 18 can not activate a sim card on their own. Be aware that many shops prefer to sell you more expensive bundles (e.g. with 3G USB sticks) stating they ran out of stock of naked prepaid SIM cards. But where there are bundles, there are 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. This 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 covers 70% of population in 2015: 4G Cosmote Coverage. 4G/LTE is given out without surcharge to all customers, including prepaid plans.

Cosmokarta and What's up
Their prepaid SIMs for talk, text and data are called Cosmokarta and What's up. They are both available for 5.01 EUR without credit in their stores (store locator).You can also obtain a SIM from specific kiosks and service stations, but this is not preferred. 4G/LTE is enabled by default, wherever there is coverage.

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 incur a fee of 3 EUR.

Topping up can be done by internatl. credit cards online from 5 to 30 EUR or by buying Cosmote Top-up cards at 5, 10, 20 or 30 EUR in their outlets. A top-up of 30 EUR or more gets 10% bonus. But a 12% telecommunication tax is applied to all top ups. So if you load 5 EUR, you'll actually get 4.86 net worth.

Default rate on both plans is the daily tariff of 1 EUR in 24 hours and 20 MB maximum up to 3G speed. If used more, speed will be reduced.

These data bundles can be booked both on Cosmokarta and What's up:

Both packages can be subscribed by calling 1330 free of charge and can be renewed anytime. Other packages for domestic calls and SMS are offered: see here all the packs for Cosmokarta and here all the packs for What's up (in Greece only).

Tazamobile
Tazamobile is a MVNO on Vodafone network in 2G and 3G. The points of sale to get a sim card are limited, as you can not obtain a SIM card directly from a Vodafone store. Getting a Tazamobile top-up voucher is also more difficult than obtaining one for an MNO, but regular Vodafone scratch cards work too on Taza.

Availability
Mostly the SIMs and top-up vouchers can be purchased at small kiosks which sell magazines and newspapers, found scattered around the city centers. But you can find actual Taza stores: store locator too.

Data rates
You can add these regular data bundles valid for 30 days: Their data top-up bonuses have been discontinued.

 * 500 MB: 5 €, activation: text 'SURF100' to 19109

Tethering and APN
Tethering seems to be blocked: Whilst the SIM worked fine in a hot-spot device, it would not give internet access in an Android phone to a tethered device, although internet on the phone was OK. The APN normally given is “internet.vodafone.gr”, but internet reports suggest “webonly.vodafone.gr” will allow tethering off a smartphone to multiple devices. Another earlier contribution suggested “webcarta.vodafone.gr” does the same thing. Comments from others may be useful on this point. In both cases username and password are left empty.
