1 · The short answer
Turkey is outside the EU, so the roam-like-at-home allowance on an EU SIM stops at the border, and most carriers bill Turkey as a roaming zone of its own. Buy a data eSIM before you fly instead. Ringo Light's Turkey plan covers the whole country, Istanbul to the Turquoise Coast, as a trip plan: unlimited data at full speed, 2 weeks for $12.99 or 30 days for $26.99, with nothing that renews. The plan is at ringoesim.com/turkey.
Turkey is not on the Europe plan; it is on the Middle East plan (12 countries, 2 weeks for $45.99 or 30 days for $62.99), for a trip that goes on from Istanbul. For Turkey alone, the Turkey plan is the cheaper one.
For a longer stay or a trip that keeps going, the Global plan is $49.99 a month for 133 countries and renews until you cancel. The card to buy any plan is below this article.
2 · Outside the EU: what your own SIM does in Turkey
Many travellers assume Turkey roams like Greece, a short ferry away. It does not. Turkey is in neither the EU nor the EEA, so an EU carrier is free to charge what it likes, and on many plans the rate is high enough to notice after one day of maps. British, American and Australian carriers treat Turkey the same way: a daily pass at best, a price per megabyte at worst.
The catalogue's answer to whether a European plan covers Turkey: Ringo Light's Europe plan does not include it, and so does the Middle East plan. Other brands' Europe plans differ, and some leave Turkey out, so check the country list before you buy a regional plan anywhere.
Before you land, switch your own SIM's data roaming off. It keeps your number reachable for calls and the text codes your bank sends, without the data bill; the eSIM carries the data. Our guide to has the settings.
3 · The 120-day phone registration rule
Turkey has a rule that worries visitors more than it should. A phone brought in from abroad and used with a Turkish SIM card is blocked on Turkish networks after 120 days unless its IMEI, the phone's serial number, is registered and a fee paid. It exists to stop phones being imported without tax.
A travel eSIM is not a Turkish line. It is a foreign operator's profile that roams on Turkish networks, the way your own SIM does when you roam, and as we understand the rule, roaming lines are outside it. For a holiday of a few weeks the question does not arise either way.
Where it matters: if you plan to stay for months, or to buy a Turkish SIM for a local number, check the current rules with the operator or at the airport shop before you rely on this. The rules have changed before, and we would rather you heard it from them.
4 · Istanbul
Istanbul has full coverage across both shores, 4G nearly everywhere and 5G arriving. The phone does three jobs here: maps through a street plan that confuses everyone, a ride app (BiTaksi and Uber both work with the city's yellow taxis), and the ferry and tram times.
The ferries across the Bosphorus are the best value in the city and the way locals cross. A rechargeable Istanbulkart works on ferries, trams, the metro and buses; the top-up machines take cash and cards. The crossing is short enough that signal on board is rarely a question.
5 · Cappadocia and Pamukkale
Most people fly from Istanbul to Kayseri or Nevşehir and transfer to Göreme. The balloon flights leave before dawn and are weather dependent: the operator tells you the night before, or at four in the morning, by message. A phone that is online in your room is the difference between hearing the flight is cancelled and standing in the cold.
Göreme, Ürgüp and Uçhisar are connected. In the valleys between them, on the walks through the Rose and Red valleys, signal comes and goes; download the map before you set off. Pamukkale, a long drive or a night bus west, has coverage at the travertines and in the village below.
6 · Antalya and the Turquoise Coast
Antalya airport is the gateway to the coast. The road west through Kemer, Olympos, Kaş and Kalkan to Fethiye and Ölüdeniz has coverage in the towns and for most of the way between them, with gaps where the road climbs behind the headlands.
Two places to plan for. The Lycian Way, the long-distance path along the coast, has long stretches with little or no signal on any network. And a gulet trip between bays is out of range for hours at a time; the boat's Wi-Fi, if it has any, usually runs on the same masts.
