Turkey blocks unregistered foreign devices and some travel eSIMs after a period because of its IMEI-registration system. The Simbye Turkey eSIM stays connected by using local carrier partnerships, so travelers keep working data throughout their trip.
If you have read that "eSIMs stopped working in Turkey" or that your data died a week or two into your trip, you are not imagining it. Turkey runs one of the strictest device-registration regimes in the world, and it affects both physical phones and certain travel eSIMs.
This guide explains exactly what the Turkey eSIM block is, why some travel eSIMs stop working mid-trip, and how the Simbye Turkey eSIM keeps you online from arrival to departure.
What the Turkey eSIM "block" actually is
Turkey does not ban eSIM technology. eSIMs are fully legal and widely used by locals and visitors alike.
What Turkey does have is an IMEI-registration system. Every phone has a unique hardware identifier called an IMEI. When a foreign phone connects to a Turkish mobile network, the country's central registry starts a clock on that device.
If the IMEI is not registered with the authorities, internet and cellular access on that device is throttled or blocked after roughly 120 days of first network use. Registration is not free either: it is effectively a device tax that currently runs around ₺20,000, which is far more than most travelers would ever pay for a short trip.
Two separate things can therefore go wrong:
- Device-level block: your phone's IMEI is unregistered and gets cut off after the ~120-day window.
- Network-routing block: some travel eSIMs lose service much sooner because of how they connect, not because of your device. More on that below.
For most travelers the device IMEI rule is not the immediate problem, since few people stay 120 days. The faster, more common headache is the way some travel eSIMs route their data.
Why some travel eSIMs stop working mid-trip
Many international travel eSIMs do not connect you directly to a Turkish carrier. Instead, they route your traffic through a foreign home network that then roams onto Turkish towers. That works fine in many countries, but in Turkey it creates two problems.
First, because the connection is treated as foreign roaming rather than a genuine local line, it is more exposed to access restrictions and can be cut off early, sometimes after only 10 to 14 days, even if you still have data left on your plan.
Second, there is the platform-access issue. On 10 July 2025, Turkey's regulator (BTK) issued a decision that produced network-level blocks against eight global travel eSIM storefronts: Airalo, Saily, Holafly, Nomad, Instabridge, Mobimatter, Alosim and BNESIM. The technology itself was not banned, and profiles installed before arrival generally kept working until they expired. But travelers who tried to buy, top up or manage a plan through one of those blocked apps while inside Turkey could be left stranded.
So you can end up offline two ways: your roaming-based eSIM gets throttled early, or the app you need to renew it is itself unreachable from inside the country.
How to stay connected in Turkey
The reliable fix is an eSIM that connects you as a local line through Turkish carrier partnerships, rather than routing you in as foreign roaming.
That is exactly how the Simbye Turkey eSIM is built. Because it runs on local carrier partnerships, your phone sees a proper in-country connection, which keeps working data flowing across your whole trip instead of dropping out after a week or two.
A few practical things that make it dependable:
- Install before you fly. You receive a QR code instantly by email and add the eSIM while you still have home internet, so you land already connected.
- Local carrier routing. The plan is designed around Turkish network partners rather than distant foreign roaming, which is what causes the early cut-offs.
- No app needed in-country. Once the profile is installed, you do not depend on reaching a storefront app from inside Turkey to keep your data alive.
- 30-day validity. Plenty of runway for a normal holiday or business trip, and comfortably inside the IMEI window.
Simbye Turkey eSIM vs. unregistered roaming and foreign eSIMs
| What matters | Simbye Turkey eSIM | Unregistered phone roaming | Many foreign travel eSIMs |
|---|---|---|---|
| How it connects | Local Turkish carrier partnerships | Your foreign SIM roaming in | Foreign home network roaming in |
| Risk of early cut-off | Built to stay connected | High once IMEI window closes | Can drop after ~10-14 days |
| Needs an app inside Turkey | No, install once and go | No, but you carry your own number | Often yes, and some apps are blocked |
| Setup | Instant QR, install before you fly | None, but roaming fees apply | QR install, varies by provider |
| Starting price | From $3 | Carrier roaming rates | Varies by provider |
The pattern is simple: anything that reaches Turkish towers as foreign roaming is exposed to early cut-offs, while a plan built on local carrier partnerships is designed to keep working.
Tips to stay online in Turkey
- Do not rely on hotel Wi-Fi alone. It is fine in the lobby, but useless for maps, ride-hailing or payments out on the street.
- Install your eSIM before departure. Add the profile while you still have home internet so you arrive already connected, not hunting for signal at the airport.
- Avoid buying data from an app once you are inside Turkey. If that storefront is blocked, you are stuck. Sort your data out before you land.
- Keep a backup. A local operator SIM or a second eSIM profile is cheap insurance if anything goes wrong.
- Watch the 120-day clock only if you are staying long term. For a normal trip the device IMEI rule will not affect you, but digital nomads should plan around it.
- Use a lawful VPN for privacy, not as a fix. VPNs are legal in Turkey, though some services are filtered. A VPN does not solve an early eSIM cut-off; the right local-routed eSIM does.

Frequently asked questions
Is eSIM banned in Turkey?
No. eSIM technology is fully legal in Turkey. What exists is an IMEI-registration system that blocks unregistered foreign devices after about 120 days, plus access restrictions that hit some foreign travel eSIM storefronts. An eSIM running on local carrier partnerships, like the Simbye Turkey eSIM, stays connected.
Why did my travel eSIM stop working after a week or two in Turkey?
Many travel eSIMs route your data as foreign roaming through a home network abroad. In Turkey that kind of connection can be cut off early, sometimes after only 10 to 14 days, even if you still have data left. An eSIM built on local Turkish carrier partnerships avoids that.
What is the Turkey IMEI 120-day rule?
When a foreign phone first connects to a Turkish network, a clock starts. If the device's IMEI is not registered with the authorities within roughly 120 days, internet and cellular access on that phone is throttled or blocked. Registration is effectively a device tax of around ₺20,000, so most short-stay travelers simply leave before the deadline.
How much does it cost to register a foreign phone in Turkey?
Registering a foreign device's IMEI currently costs around ₺20,000. For a short trip this is rarely worth it, which is why travelers usually rely on a properly routed local eSIM and stay well inside the 120-day window instead.
Which eSIM providers were blocked in Turkey?
On 10 July 2025, Turkey's regulator BTK produced network-level blocks against eight international travel eSIM storefronts: Airalo, Saily, Holafly, Nomad, Instabridge, Mobimatter, Alosim and BNESIM. Profiles installed before arrival generally kept working, but buying or topping up through those blocked apps from inside Turkey was the problem.
Does the Simbye Turkey eSIM work despite the block?
Yes. The Simbye Turkey eSIM connects through local carrier partnerships rather than foreign roaming, so it is designed to keep working data flowing across your whole trip. You install it once from a QR code, with no need to reach a storefront app once you are inside the country.
Should I install my Turkey eSIM before or after I arrive?
Install it before you fly. You get the QR code instantly by email, so you can add the profile while you still have home internet and land already connected. This also sidesteps the risk of needing a blocked app once you are in Turkey.
How much does the Simbye Turkey eSIM cost?
Plans start from $3, with 30-day validity and instant QR delivery. You can browse the options on the Simbye Turkey eSIM page.
