Turkey IMEI Registration: The 120-Day Rule Explained

Turkey IMEI registration costs 54 258 TL in 2026 (Resmî Gazete № 33124), filed only via e-Devlet. A foreign SIM past 90 days of data in 120 is cut off.

Does this apply to you? (a 120-day test, first screen)

Turkey IMEI registration affects you only past 120 days on one device inside the country — most trips end long before that line. IMEI registration Turkey rules exist for the long-stay case, not for a two-week holiday.

Count from your last entry date, not from the day a Turkish SIM first went into the phone. BTK’s consumer FAQ ties the clock to entry; the regulation itself runs the 120 days from the day an unregistered phone, seen on a Turkish operator’s own SIM, goes on the black list. Entry is the earlier of the two starts, so counting from entry is the safer assumption. A phone that only roams on a foreign SIM has a separate limit, set out further down: more than 90 days of data in any 120. Under 120 days on any single device, none of the fee, the binding rule, or the roaming limit reaches you. Past it, you are in scope: residents and long-stay visa holders, digital nomads who never really leave, gurbetçi diaspora phones carried home each summer, and anyone whose phone has already gone dark and wants to know why.

What the regulator actually publishes: 120 days, and what happens on day 121

BTK Tüketici, the regulator’s consumer-facing site, publishes the number. Past 120 days from entry, an unregistered device is closed to every Turkish network.

“Yurtdışından getirilen telefonlar 120 gün kayıt yaptırmadan kullanılabilmektedir.” — Phones brought from abroad may be used for 120 days without registration. “Cihaz 120 gün içinde kayıt edilmemesi durumunda iletişime kapatılmaktadır.” — If the device is not registered within 120 days, it is closed to communication. — BTK Tüketici, checked 10 August and again 20 October 2026

Day 121 runs through EIR device blocking — the Equipment Identity Register, the shared blacklist all three Turkish networks read against. The regulator calls this iletişime kapatma: closed to communication. Turkish press paraphrases BTK’s position as no calls, SMS or mobile data on that IMEI, on any SIM. A registered device stays registered unless it goes a full year without service on Turkish networks; its IMEI then moves to the black list until it is reactivated through e-Devlet (Yönetmelik No. 19873, Articles 6 and 10).

One claim in circulation says the grace period was extended to 180 days, with no official confirmation: BTK Tüketici and the regulation still say 120, checked 20 October 2026. The 365-day figure is a different deadline: the window to file a registration after entry, which the regulation says does not extend the 120 days of use (Article 14(4)). MCKS currently words its FAQ as if 365 were the cut-off — “Cihazın 365 gün içinde kayıt edilmemesi durumunda iletişime kapatılmaktadır” — while the regulation keeps the two figures apart.

The fee: 54 258 TL — and why one source says 57 241

The 2026 duty is 54 258 TL, the figure printed in the Gazette tariff itself. A second figure, 57 241 TL, ranks for this exact search, and this page shows where it comes from rather than leaving it unexplained — a sourcing rule here.

The primary number traces to the Harçlar Kanunu fee schedule itself. Harçlar Kanunu Genel Tebliği Seri No: 98 ran in the Official Gazette (Resmî Gazete) on 31 December 2025, issue № 33124 (5. Mükerrer), and took effect 1 January 2026. Its tariff, section VIII, prints the fee for a phone brought in by a passenger as 54 258,00 TL, payable before the IMEI is registered (read again on 20 October 2026). The 2025 figure was 45 614 TL; Article 3 of the Tebliğ raised fixed fees by 18.95%, not by the 25.49% revaluation rate it also records.

A second figure, 57 241 TL, comes from turkeytravelplanner.com, the top US result for “register foreign phone turkey” on 10 August 2026.

“The cost of registering a foreign phone in Turkey is 57,241 TL as of January 1st, 2026. The cost in 2025 was 45,614 TL.” — turkeytravelplanner.com, checked 10 August 2026

Both sources agree on the 2025 baseline and the 1 January 2026 start date. The Gazette settles the 2026 figure: 54 258 TL.

The gap has an arithmetic shape worth seeing. Take the 2025 base both sources give, 45 614 TL. Raise it 18.95% and you get 54 258 TL, the Gazette figure. Raise it 25.49%, the unreduced revaluation rate before the President’s cut (both rates print in the Tebliğ itself, Article 3), and you get 57 241 TL, to the lira. So 57 241 TL is the 2025 fee raised at the rate Article 3(3) says was not applied; the Tebliğ raised fixed fees by 18.95%, which gives the 54 258 TL its tariff prints.

The commercial guide holding the top US result for “turkey imei registration” on 10 August 2026 gets both facts wrong: a duty of roughly ₺3 000–4 000, and registration done in person at a PTT branch. Neither holds up against the Gazette text or the e-Devlet route below.

By this project’s working exchange-rate range — 40–43.5 TRY/USD, an internal assumption, not a verified market rate — 54 258 TL converts to roughly $1 250–1 360. In dollars, that usually costs more than the phone itself.

For your own handset — here and in Indonesia, Pakistan, Nepal and Egypt — the IMEI registration fee calculator applies each regulator’s published formula and shows both Turkish figures side by side.

The Gazette figure is 54 258 TL; the second figure appears here only so you can recognise it.

The binding nobody mentions: one IMEI opens for one Turkish number

Buy a local Turkish SIM as a tourist, and the state pairs your handset’s IMEI to that one phone number inside a government database — a rule stated plainly on the regulator’s own site and repeated almost nowhere else in this topic’s coverage.

MCKS, the Mobil Cihaz Kayıt Sistemi, publishes it directly:

“Geçici süreyle Türkiye’de bulunan kişilerin (turist, gurbetçi vatandaşlar ve benzeri) […] işletmeci tarafından kişilerin cihazlarına ait IMEI numarası ve sözleşme yapılan cep telefonu numarası Mobil Cihaz Kayıt Sistemi’ne girilmek suretiyle eşleştirilmekte ve ilgili IMEI numarası sadece ilgili telefon numarası ile kullanıma açılmaktadır.” — For people temporarily in Turkey (tourists, gurbetçi diaspora citizens and similar), the operator enters the person’s device IMEI and the contracted phone number into the Mobile Device Registration System and pairs them; that IMEI opens for use only with that phone number. — MCKS, checked 10 August 2026

That is the one IMEI one Turkish number binding, done at the point of sale. Passport and subscription contract go to the operator at the point of sale, where the pairing is entered — what that counter asks for, and how many lines it will sell you, is a separate set of rules. Switch numbers later, and the phone does not follow; the pairing must be redone at the same counter.

A traveller on a travel eSIM does none of it. No passport handed across a counter, no IMEI paired to a number inside MCKS. The handset is not invisible, though: while it roams, its IMEI sits on the regulator’s grey list of devices served temporarily in Turkey (Article 7), and the roaming limit below applies to it. That is a real, official difference in what happens to your device, not an argument about what anything costs.

The roaming limit: more than 90 days of data in any 120

A phone on a foreign SIM does not run the 120-day clock as such: the regulation writes that usage period for phones on a Turkish operator’s own SIM (Articles 2(1)(a) and 4(1)(h)) and gives roaming a limit of its own. Article 4(1)(ö) of the device-registration regulation, Yönetmelik No. 19873, defines permanent roaming: “IMSI öneki 286’dan farklı olan ve ardışık yüz yirmi gün içerisinde kümülatif olarak doksan günden fazla ses haberleşmesi … olmadan şebekede iz bırakarak alınan daimi dolaşım hizmeti” — a SIM whose IMSI prefix is not Turkey’s 286, used on the network for more than 90 days in total within any 120 consecutive days without a voice call. Such a device goes on the black list, and Article 10(2)(e) has the operator cut it off within thirty days; the user’s foreign operator is told (Article 10(1)). Since 2 July 2026 (Resmî Gazete № 33298), sending text messages no longer counts as the use that keeps a device out of this definition. A data-only travel eSIM makes no voice calls, so every day it is used counts.

That settles what this page used to call an open question. A trip under 90 days never reaches the roaming limit. For the 120-day clock on a Turkish SIM, two starts still circulate:

Field report

“Yurt dışından alınan telefon Türkiye’deki GSM şirketlerine ait SIM kartlar takılıp kullanılmaya başlandığında 4 aylık süreç başlıyor.” — The four-month process begins once a phone bought abroad has a Turkish carrier’s SIM inserted and used. (Turkish press; the majority position on a long DonanımHaber forum thread.) “Yurda giriş tarihinden itibaren.” — From the date of entry into the country. (MCKS, BTK Tüketici — ties the clock to arrival instead, directly conflicting with the line above.)

On roaming, the regulation answers both camps that used to argue on forums: roaming on a foreign SIM does not run the 120-day clock, and it is not limitless either — past 90 days of data in 120, the IMEI is blocked. The catalogue’s own Turkey listing states the same 91-in-120 threshold.

Two starts for a Turkish SIM; one separate limit for roaming.

Traveller reports match that rule. Querying an eSIM’s IMEI through e-Devlet in April 2026, one traveller got back this message.

Field report

“The device was shut down because it was involved in continuous international data circulation. (Under Law No. 7186-24)” — u/Comfortable-You3642, r/AskTurkey, 16 April 2026

A second, independent account on travelask.ru describes the identical wording, from someone who states plainly a Turkish SIM was never inserted in that device — only a foreign SIM in roaming, for over three years.

“Устройство выключено, поскольку находится в постоянном международном роуминге данных.” — The device was shut down because it is in continuous international data roaming. — Anastasia, travelask.ru, ~2025

Two witnesses, two languages, roughly a year apart, and both describe the regulation’s own term: “daimi veri dolaşım”, permanent data roaming. The “7186” reference in the first message is one we could not trace to a statute.

Two mechanics are not in dispute, whatever the trigger turns out to be. Most phones carry two SIM slots, each with its own IMEI, and an eSIM profile occupies one of the two rather than creating a new one.

Field report

“You can not have 3 IMEI numbers.” — u/Mental_Seaworthiness, r/AskTurkey, 25 December 2025

And the counter runs per IMEI, not per eSIM profile.

Field report

“It’s 120 days for per IMEI not per esim. If you remove an esim and add another one it won’t be reset.” — u/Tight-Accident-5686, r/AskTurkey, 26 July 2026

Swapping the eSIM profile buys nothing if the underlying slot is the one already blocked.

If your device is already blocked, an eSIM will not help you

No. If your device is already blocked in Turkey’s device registry, a travel eSIM will not bring it back — the block sits on the device’s IMEI, not on which SIM or eSIM profile you try next.

The mechanism explains why. EIR device blocking runs at the network level, shared across Türk Telekom, Turkcell and Vodafone, and it closes the IMEI itself to calls, SMS and mobile data on any subscription. The catalogue’s Turkey plan roams on the Türk Telekom network — the same network reading the same blacklist. So the network that already refuses that IMEI refuses it again with a travel eSIM in the slot. The regulation says as much: operators cut off a black-listed IMEI, and for a permanent-roaming device the user’s foreign operator is told (Article 10). We are not going to take your money on the chance it works anyway.

Do not buy a travel eSIM expecting it to unblock a foreign phone blocked by BTK’s device registry. Check whether the eSIM block or the device block is what you are actually dealing with first.

Whether the block is permanent, the community itself does not agree.

Field report

“I think once it’s blocked that IMEI is banned permanently. At least that’s been the case with two of my friends.” — u/Foreign_Attitude_584, r/AskTurkey, 24 December 2025

“The block is for the calendar year. Then it resets for another 120 days.” — u/aegeandad, same thread, r/AskTurkey, 24 December 2025

Both are lived experience, not regulator statements, and they disagree.

How registration actually works (e-Devlet only — the PTT branch is a myth)

e-Devlet registration is the only route — turkiye.gov.tr/btk-imei-kaydet — never a PTT branch counter in person, whatever the PTT branch myth still repeated by at least one ranking guide claims. Dial *#06# to find your IMEI before you start. The duty is paid separately, through GİB, Turkey’s tax authority, via dijital.gib.gov.tr or ivd.gib.gov.tr. Since 2 July 2026 the regulation itself names e-Devlet as the only place to apply (Article 4(1)(c), Resmî Gazete № 33298), and BTK’s FAQ adds that the duty can also be paid at a tax office or a bank linked to the system.

Registration runs through the e-Devlet portal. There is no PTT-branch route.

Whoever imported the device registers it, tied to their own passport and entry record. That is where the tourist path mostly ends. Registration needs an e-Devlet account, and an e-Devlet account needs a Turkish national ID number or a residence permit. Most tourists hold neither.

The regulation and BTK’s FAQ confirm both limits Turkish sources describe. A new registration needs at least three calendar years since the entry date of your last registered device (BTK Tüketici: “en az üç takvim yılının geçmesi gerekir”), and a registered phone stays tied to the passenger’s own numbers for three calendar years (Yönetmelik, Articles 8(1)(d) and 12(3)). Registration must be filed within 365 days of entry (Article 14(4)) — a window that does not stretch the 120 days of use.

Once registered, the handset stays a passport-linked device for three years. It works only with SIM numbers held by whoever paid the duty. Only after that does it open to any subscriber — a rule meant to stop registered phones being resold as a workaround.

Enforcement is dated and active. Since 1 January 2026, BTK has begun disconnecting phones registered under a fake second IMEI. The scheme, “tek pasaport iki telefon” — one passport, two phones — used dual-SIM handsets with a declared first and second IMEI that did not belong to the same device (Memurlar.net, 1 January 2026).

FAQ

Before you decide

The short version of Turkey IMEI registration, before you act:

• Count days from your last entry date, not from the day a Turkish SIM went in; entry is the earlier start, so it is the safer one to count from.
• The 2026 duty is 54 258 TL (Resmî Gazete № 33124); a guide quoting 57 241 TL used the revaluation rate the Tebliğ did not apply.
• Registration happens only through e-Devlet; no PTT branch completes it, in person or otherwise.
• A device already blocked in Turkey’s registry stays blocked on a travel eSIM too — it rides the same networks.
• A roaming-only eSIM has its own limit: more than 90 days of data in any 120, and the IMEI is blocked within 30 days.

Last verified against MCKS, BTK Tüketici, the Official Gazette and the device-registration regulation (Yönetmelik No. 19873, as amended on 2 July 2026): read 20 October 2026. The duty is revised annually, typically in late December; the 2027 figure was not yet published on that date.
