How to Get a Turkish SIM Card
as a Foreigner

Tourist/visitor prepaid packages run roughly ₺420–1,850 per month (about $9–$39) depending on operator, store, and data allowance — Türk Telekom is usually cheapest, Vodafone's larger data bundles the most expensive. The SIM card itself is typically bundled into that first package rather than sold separately. Postpaid contracts for residents with a tax number are often better value per GB but carry a few small recurring government fees on top (line-opening charge, annual radio-use fee, communications tax).

No. You can buy a prepaid SIM with just your passport, on your first day in the country. A Turkish tax number (vergi numarası) becomes necessary once you want to pay the IMEI registration fee or open a postpaid contract, and a residence permit is generally required to register a second or third line as a foreign resident.

IMEI registration links a foreign-bought phone's unique device identifier to a Turkish tax record so it can keep working on Turkish networks past the 120-day grace period. The fee is revalued every January by presidential decree — it is ₺54,258 for 2026 (about $1,260), up from ₺45,614 in 2025, an increase of roughly 19%. Phones purchased inside Turkey are pre-registered and don't require this fee.

The device is blocked from every Turkish mobile network — Turkcell, Vodafone, and Türk Telekom simultaneously. It will still connect to Wi-Fi normally, but no SIM (Turkish or foreign, via roaming) will get a signal in that handset until the IMEI is registered and the fee paid.

Three steps: (1) get your IMEI by dialling *#06# on the phone; (2) pay the registration fee, either in person at a Vergi Dairesi (tax office) or online via e-Devlet (search "Cep Telefonu Harcı Ödeme" then "IMEI Kaydet" — you'll need an e-Devlet password, obtainable at a PTT post office); (3) bring the phone, your passport, and the payment receipt to any Turkcell, Vodafone, or Türk Telekom store to have the IMEI linked to your line.

Under a BTK regulation published in the Official Gazette on 25 June 2026, tourists may register just 1 line per passport, foreign residents with a valid residence permit may register up to 3, and Turkish citizens up to 6. Existing foreign subscribers with more lines than the new cap were given a 6-month window to transfer or cancel the excess at no cost.

You can, but two things to know: roaming rates from most home carriers for extended stays in Turkey are expensive compared to a local package, and the phone's IMEI still starts its 120-day clock the moment it connects to a Turkish network — whether via roaming or a Turkish SIM. Buying a local SIM is almost always cheaper for anything longer than a short holiday.

Turkish operators themselves fully support eSIM — Turkcell, Vodafone, and Türk Telekom will activate one for a compatible device in their stores. What changed is that since July 2025, Turkey's BTK has restricted in-country access to several international eSIM providers' apps and websites (Airalo, Holafly, Saily, Nomad, Instabridge, and others), reportedly because they route data through foreign infrastructure. An eSIM from one of those providers installed and activated before you arrive typically keeps working; you generally can't purchase or top one up once you're connected to a Turkish network.

Turkcell has the widest network coverage, including rural and mountain areas, plus the best English-language app and customer support — most long-term expats default to it. Vodafone is a close second with strong urban coverage. Türk Telekom is usually the cheapest option and fine if you mostly stay in cities, but has weaker rural coverage and less English support.

City-centre operator stores are generally cheaper than airport kiosks for the same package, though airports are more convenient the moment you land. If your accommodation isn't far from a store, it's worth waiting a day rather than buying at the terminal.

Yes. Once you have a Turkish tax number, you can walk into any operator store and convert your existing prepaid number to a postpaid (faturalı) contract, or open a new postpaid line. Many expats deliberately start prepaid in month one and switch once they have their paperwork sorted.

A prepaid line usually stays registered to you as long as you top it up periodically (operators typically deactivate lines after a few months of total inactivity — check the specific policy with your operator). Postpaid contracts continue billing regardless of whether you're in the country, so cancel or pause the line with your operator if you're leaving for an extended period.

Not for your first prepaid line — passport alone is enough. You'll need the tax number for the IMEI registration payment step and for opening a postpaid contract, so it's worth getting one from any Vergi Dairesi in your first week; the process is free and usually takes under 30 minutes.

Law No. 7571, in force since 25 December 2025, is separate from the June 2026 SIM-count cap — it requires operators to verify every foreign subscriber's identity in real time against Presidency of Migration Management (Göç İdaresi) records, using biometric checks or e‑Devlet authentication. New purchases are verified automatically at the point of sale. If you already had a Turkish SIM before that date, your operator should have prompted you to complete this verification — lines that stay unverified face outgoing-call restrictions after 30 days and full deactivation after 90. If you're unsure whether an older line is compliant, check your operator's app or visit a branch with your passport.

You can, but it is usually the most expensive option for anything beyond a few days. Turkey is not part of the EU's "Roam Like at Home" zone, so EU/EEA citizens pay standard extra-EU roaming rates rather than home-country rates, and non-EU roaming is typically pricier still. A local Turkish SIM or a pre-purchased travel eSIM is almost always cheaper for a stay longer than a short holiday — and note that the IMEI's 120-day clock starts the moment the phone connects to a Turkish network at all, including via roaming.
