Can I use eSIM and a physical SIM to get more than 120 days?

Yes, with a dual-SIM or eSIM-capable phone. Each SIM slot has its own distinct IMEI number, so using the physical SIM slot gives you 120 days, and switching to the eSIM slot afterward gives you another 120 days — up to 240 days per calendar year across both.

Why do I need a local +90 number if I already have an eSIM?

Because eSIMs from providers like Airalo or Holafly are data-only — they can't receive SMS. A local +90 number is required for Turkish bank account 2FA/OTP codes, Göç İdaresi and PTT residency notifications and UAVT codes, and local apps like Getir, Yemeksepeti, BiTaksi, and Sahibinden.

How do I avoid the airport SIM card markup?

Install a low-cost 1–3GB eSIM before you fly and use it for airport navigation, messaging, and booking a taxi or ride to your accommodation. Airport kiosks at IST and SAW commonly charge $60–$80 for basic tourist SIM packages that cost $12–$25 at a city-center Turkcell or Vodafone store.

When should I convert my tourist SIM to a residential plan?

Once your residence permit card (e-İkamet) is delivered, visit your mobile operator’s store within 90 days to convert your temporary tourist line into a standard monthly postpaid or prepaid residential contract — tourist SIMs deactivate after 90 days otherwise.

eSIM vs. Local SIM Card in Türkiye: 2026 Comparison & Setup Guide

Q: What is the 120-day IMEI rule in Türkiye?

Any foreign mobile device using a local Turkish SIM network (physical or eSIM) can operate for up to 120 days per calendar year without paying the national IMEI registration tax (MCKS / BTK registration). After 120 days, the phone’s hardware identifier (IMEI) is blocked from Turkish mobile towers until the tax is paid or you leave the country.

Mobile Data & The Turkish IMEI Registration Rule

Setting up mobile internet in Türkiye involves more than picking a data plan. Foreigners bringing an unregistered foreign phone into Türkiye encounter telecommunications regulations overseen by the Information and Communication Technologies Authority (BTK).

The rule: any foreign mobile device using a local Turkish SIM network (physical or eSIM) can operate for up to 120 days per calendar year without paying the national IMEI Registration Tax (MCKS / BTK Registration).

Network blocking: after 120 days, the phone's IMEI is blocked from registering on Turkish mobile towers (Turkcell, Vodafone, Türk Telekom) until the tax is paid or you leave the country.

Dual-SIM workaround: dual-SIM or eSIM-capable phones have two distinct IMEI numbers. Using the physical SIM slot gives you 120 days; switching to the eSIM slot afterward gives you another 120 days — up to 240 days per calendar year.

The "Airport Tourist SIM Trap" vs. City Center Purchase

One of the most common budget pitfalls for new arrivals happens at New Istanbul Airport (IST) and Sabiha Gökçen Airport (SAW): mobile operator kiosks in the arrival halls charge heavily inflated "tourist package" prices — frequently $60 to $80 USD for basic 20GB tourist SIM cards.

The Smart Alternative

Install a 1GB–3GB regional eSIM before departing for Istanbul and use it for airport navigation, messaging, and booking a BiTaksi or Uber to your accommodation. Once settled, visit an official Turkcell or Vodafone branch in Kadıköy, Beşiktaş, Taksim, or Şişli for a local tourist SIM at official retail rates (400–800 TRY).

Why Long-Term Expats Need a Local +90 Number

While data-only eSIMs work well for short trips, living in Istanbul requires a local Turkish phone number for daily digital infrastructure:

Banking & OTP

Garanti, Ziraat, and Kuveyt Türk all require 2FA SMS codes to a Turkish number to open an account.

e-İkamet & Address Codes

The Migration Directorate and PTT issue status notifications and address codes exclusively via SMS to local numbers.

Daily Apps

Getir, Yemeksepeti, BiTaksi, and Sahibinden all require a +90 number for courier confirmation and account activation.

Recommended Hybrid Strategy for Nomads & Expats

1Install a 1–3GB eSIM before your flight
2Land at IST/SAW with instant connectivity
3Buy a local Turkcell/Vodafone SIM in the city center

Connectivity Checklist for New Arrivals

Before flying: verify your phone is carrier-unlocked and eSIM-compatible.
Before flying: download an eSIM profile with 1–3GB data for immediate airport arrival use.
Arrival day: decline $60–$80 airport SIM offers; use your eSIM for taxi/transit data.
Days 2–5: purchase a local SIM card (+90 number) at a city-center store using your passport.
Long stays (120+ days): track your 120-day IMEI clock per SIM slot to avoid network shutoff.
