📱 SIM cards and eSIM in Türkiye: the IMEI rule

The three operators

The mobile operators you will see at the airport and in the street are Turkcell, Vodafone and Türk Telekom. All three sell prepaid tourist packages, as a physical SIM and, in many cases, as an eSIM.

Turkcell’s official tourist page lets you apply online, then activate an eSIM in the Turkcell app (you need a biometric passport and a phone that supports eSIM and NFC) or pick up a physical SIM or eSIM at a Turkcell store with your passport. Packages are for use in Türkiye and are aimed at visitors arriving within a 90-day window. Only a passport is accepted as ID on that official flow.

Vodafone and Türk Telekom also sell tourist SIMs at airport shops and official stores; a passport is the document they ask for. I am not quoting package prices, because they change with the campaign — compare official sites or the desk in front of you.

Bring your passport to the store. A photo on your phone is often not enough. If you already have an eSIM-compatible phone, you can often leave the shop without a plastic card.

The IMEI rule, from official BTK sources

This is the part to understand clearly. The Information and Communication Technologies Authority (BTK) says a phone brought into Türkiye from abroad can be used on Turkish mobile networks without IMEI registration for 120 days from the date of entry. If it is not registered within those 120 days, it is blocked from mobile service here.

Apple’s official support page says the same: after 120 days you must register, or the status bar can show “No Service” on Turkish networks.

If you are visiting for a few weeks, you usually do not need to register anything. Use your tourist SIM or eSIM, and leave. The 120-day clock is about the phone’s IMEI, not about how many SIMs you buy.

Registration, when it is required, goes through official e-Devlet pages such as turkiye.gov.tr/btk-imei-kaydet. In practice it is designed for people with a Turkish ID number or a foreign ID number who can use e-Devlet. Official operator help pages also note that a short-stay tourist without a residence permit often cannot complete that registration in the same way. I am not quoting a current registration fee, because the official fee is updated and I will not invent it.

Check the official BTK consumer pages or call BTK’s consumer line 120 if your situation is unusual. This page is a practical summary, not legal advice.

Roaming, Wi-Fi and a backup plan

International roaming on your home SIM may work, but it can be expensive, and official rules have also tied some roaming use on an unregistered device to the same IMEI period. A Turkish tourist package is usually the simple option for a week or two.

Keep hotel Wi-Fi as a backup: “Wi-Fi şifresi ne?” is in the hotel lessons. Download an offline map before you leave the airport Wi-Fi, in case the SIM is not active yet.
