Turkey eSIM

Türkiye is one of the easiest countries to land online in, as long as you buy your eSIM before you fly: since July 2025, several foreign eSIM sellers' websites have been blocked from inside the country. A travel eSIM also keeps you clear of the IMEI registration that comes with putting a Turkish SIM in a foreign phone.

What a week of data costs in Türkiye

Prices for 7 days of data, checked on 2 November 2026. Türkiye isn't in the EU, so European "roam like at home" deals don't cover it. Daily passes charge each day you use the phone abroad, per phone.

For a family of four on Verizon, that's $336 for one week. The German and Swiss packs cost less but are small: 2 GB or 5 GB goes quickly on maps, photos and video calls.

Landing at Istanbul (IST), Sabiha Gökçen (SAW) or Antalya (AYT)

Most long-haul flights land at Istanbul Airport (IST), on the European side. Sabiha Gökçen (SAW) is on the Asian side and takes many budget and regional flights. Antalya (AYT) is the gateway to the Turquoise Coast resorts, and Dalaman and Bodrum take holiday flights too. Switch the kimsim line on as the plane taxis to the gate, so you can message your driver or book a ride while you queue at passport control.

Visas first. British citizens can visit visa-free for up to 90 days in any 180, and your passport must be valid for at least 150 days after you arrive. Other nationalities should check before booking, and apply only on the official site, evisa.gov.tr.

At Istanbul Airport, in order: turn on Data Roaming for the kimsim line only, walk through passport control, collect your bags and go through customs. Operator shops at the airport sell tourist SIMs; with your eSIM already working, you can walk past them. Airport Wi-Fi is free, but you log in by scanning your passport at a kiosk or with a code sent by text, so don't rely on it for your first ride.

Into the city from IST: the M11 metro runs to Gayrettepe in about 30 minutes, where you change to the M2 for Taksim. Havaist buses go to both sides of the city, and the taxi rank is outside arrivals. Uber books licensed taxis here too.

From Sabiha Gökçen: the M4 metro runs to Kadıköy, where ferries cross to the old city. From Antalya: a branch of the city tram line runs from the airport into the centre. If a resort transfer is meeting you, save the driver's number in WhatsApp before you fly.

Networks and coverage

Türkiye has three mobile operators: Turkcell (the biggest), Vodafone Türkiye and Türk Telekom. Türk Telekom's mobile network used to be called Avea, and has carried the Türk Telekom name since January 2016. The networks your plan uses are listed above, and your phone shows the Turkish operator's name, not kimsim.

All three operators switched on 5G together in April 2026 in all 81 provincial centres, and must cover the whole country by April 2028. Outside city centres, expect 4G.

Coverage is generally strong in Istanbul, Ankara, Izmir and the resort towns of the Aegean and Mediterranean coasts. Expect it to thin out in Cappadocia's valleys, on mountain roads in the east and the Black Sea highlands, and on boat trips away from the shore.

Region by region

• Istanbul: dense and well covered on the street. Expect weaker signal indoors in old stone buildings, such as the covered bazaars and the cisterns.
• Cappadocia: fine in Göreme, Ürgüp and Uçhisar. Down in the valley walks and on dawn balloon flights it can come and go, so download a map of the trails first.
• Antalya and the Turquoise Coast: good in Antalya, Kemer, Side and Alanya. Quieter coves near Kaş and Kalkan and boat days out to Kekova can be patchier.
• Bodrum and the Aegean coast: well covered in the towns. The Greek islands are a few kilometres offshore here, which is where phones can switch country (see the mistakes below).
• Ephesus and Pamukkale: usually fine at the entrances and in Selçuk and Denizli. Save your tickets before you walk the ruins or the travertines.
• The east and the Black Sea: long, mountainous drives with gaps between towns. Plan to be offline for stretches.

This is general guidance, not a coverage map. If your plan offers more than one network and one is weak where you're staying, switch network by hand.

Ferries, buses, trains and flights

Istanbul's ferries cross the Bosphorus and run out to the Princes' Islands; signal is usually fine on the short crossings. The Istanbulkart travel card works on the metro, trams, Marmaray trains, city ferries and buses.

High-speed YHT trains link Istanbul and Ankara with Eskişehir, Konya, Karaman and Sivas. Long-distance coaches cover everything else, often overnight, with long stretches of countryside. Domestic flights are the quick way between Istanbul, Cappadocia (Kayseri or Nevşehir) and the coast. Download tickets, hotel details and an offline map before any long leg.

Apps worth having

• Uber works in Istanbul and books yellow taxis, paid in the app. BiTaksi is the local taxi app, in English and Turkish. Set both up at home: sign-up can send a text code to your usual number. The UK Foreign Office warns against unofficial taxis and says app-based taxis are widely available.
• WhatsApp is how hotels, transfer drivers, balloon operators and guides usually message you. Log in before you leave, and keep your WhatsApp number working abroad.
• Maps: download offline areas for Cappadocia and any coastal drive.
• Payments: cards are widely accepted in cities and resorts. Carry some lira for markets, small cafés and dolmuş minibuses.

SIM and phone rules

eSIM sellers' websites are blocked, not eSIMs. On 10 July 2025, Türkiye's telecoms regulator, the BTK, ordered access blocks on the websites of several foreign eSIM sellers, and published no reason. The UK Foreign Office says "access to some e-sim services is restricted in Turkey". So buy and install your eSIM before you fly, with enough data for the whole trip.

The IMEI rule is about Turkish SIMs. Türkiye keeps a register of phones by their IMEI. A foreign phone used with a Turkish SIM can only be used for 120 days unless it's registered on e-Devlet, and the 2026 fee is 54,258 TL. A travel eSIM roams as a visitor, and ordinary visitor roaming isn't covered by the rule.

The one catch is long stays. A foreign line with traffic on more than 90 days in any 120, and no voice calls, counts as "permanent roaming", and the phone can be cut off. For a holiday of a few weeks, it doesn't apply.

A Turkish tourist SIM needs your passport and opens a new Turkish line, which starts the phone's 120-day clock. An eSIM installed at home skips the shop and the paperwork.

Common mistakes

• Trying to buy an eSIM after you land. The block means some sellers' sites won't load in Türkiye, and you need internet to install anyway. Install on Wi-Fi before you fly.
• Leaving Data Roaming on for your home line. Türkiye is outside European roaming deals, so this is where daily charges start. Roaming goes on for the kimsim line only. Why roaming goes on for the kimsim line only
• Starting the plan on a stop-over. If you connect through another country, keep the kimsim line off until you land in Türkiye. If your plan started early
• Hopping to a Greek island on a Turkey plan. Kos, Rhodes and Samos are a short ferry ride away but in Greece. How regional plans work
• No way to call for help. Türkiye's emergency number is 112. A data-only eSIM can't dial it, so use your home line or any local phone.

How we put this page together

We checked operators' own pages, Turkish regulations in the Official Gazette, carriers' roaming price pages and the other sources noted above on 1–2 November 2026, and we'll keep them up to date. We haven't measured speeds or coverage in Türkiye ourselves, so coverage notes are general guidance, not a map. kimsim sells the eSIMs on this page.
