The 120-Day IMEI Rule & BTK Network Block
When you insert a local Turkish SIM card or eSIM (Turkcell, Vodafone, Türk Telekom) into a foreign-purchased smartphone, the Information and Communication Technologies Authority (BTK) registers your phone's unique IMEI hardware code.
The 120-day clock: a foreign device operating on local Turkish towers can function for up to 120 calendar days per IMEI slot, per calendar year, without paying national registration fees.
The network block: on day 121, BTK automatically blocks the IMEI from Turkish cellular networks. Your phone shows "No Service" locally — Wi-Fi and foreign roaming SIMs keep working.
Annual reset: the 120-day countdown is tied to the calendar year — it resets automatically on January 1st for devices that haven't been blocked yet.

The Math: 2026 IMEI Registration Fee vs. the Alternatives
Paying the official tax (MCKS / Harç Kaydı) is legally required to use a foreign phone on local networks beyond the grace period — but the cost has risen sharply, so it's worth comparing against the alternatives before paying it.
Pay Official IMEI Registration Tax
~31,600 – 45,000 TRY (~$900 – $1,300+)Best suited for: Long-term residents (2+ years) with high-end flagship phones
Key drawback: High fee; device becomes linked to your passport & YKN tax ID for 3 years (cannot swap in another person’s SIM).
240-Day Dual-SIM / eSIM Strategy
$15 – $40 (eSIM data plans)Best suited for: Digital nomads, seasonal expats, short-term residents (<8 months)
Key drawback: Requires an unlocked dual-SIM phone (physical SIM + eSIM).
Buy a Budget Local "Secondary" Phone
6,000 – 12,000 TRY (~$180 – $350)Best suited for: Expats needing a dedicated +90 local line for banking & apps
Key drawback: Carrying two physical devices (local phone doubles as a Wi-Fi hotspot).
The 240-Day Dual-SIM / eSIM Strategy
If your phone supports dual-SIM (one physical slot, one eSIM chip), you can legally double your local network access to 240 days per calendar year without paying the IMEI tax:
- 1Days 1–120: insert a local Turkish physical SIM into Physical Slot 1 (IMEI 1). Use local mobile data and your +90 number normally.
- 2Day 121: when BTK blocks IMEI 1, convert your local line to an eSIM profile at a Turkcell or Vodafone store, or activate an international eSIM (Airalo/Holafly) on eSIM Slot 2 (IMEI 2).
- 3Days 121–240: IMEI 2 gives you another 120-day countdown on the same hardware — 8 months of continuous connectivity in total.
Step-by-Step IMEI Tax Payment Process (For Permanent Residents)
If you hold a Residence Permit (e-İkamet) or Work Permit and decide to register your foreign phone permanently, follow this official process:
- 1
Check Your Passport Entry Stamp
Must be within 365 days of your entry to Türkiye — this is the registration window.
- 2
Obtain Your e-Devlet Password
Get this from any PTT (post office) branch using your passport and foreigner ID (YKN).
- 3
Pay the IMEI Registration Fee
Pay via e-Devlet or in person at the Tax Office (Vergi Dairesi).
- 4
Register Your IMEI Numbers
Must match the exact passport name and Foreigner ID Number (YKN) that entered Türkiye within the last 365 days.
Condition 1: the foreign phone must be registered under the exact passport name and Foreigner ID Number (YKN) that entered Türkiye within the last 365 days.
Condition 2: the registered local phone line (+90 SIM) must also be registered under that same passport/YKN holder — you cannot register a phone under your name and insert a line belonging to a family member or spouse.

- Check device unlocked status: ensure your smartphone is carrier-unlocked before leaving your home country.
- Find both IMEI numbers: dial *#06# on your keypad to write down both IMEI 1 and IMEI 2.
- Track your arrival date: mark calendar day 120 from the date you first inserted a local Turkish SIM card.
- Set up travel data: install an international data eSIM (Airalo/Holafly) before landing at IST or SAW.
- Evaluate long-term plans: under 8 months, use the 240-day dual-SIM method; multi-year, compare the IMEI tax cost against buying a local Turkish phone.
