Turkey is one of Europe's most popular destinations, and since the end of EU roaming for UK travellers and for anyone outside the EU, one of the more expensive ones to stay connected in. An eSIM is the obvious answer — except that Turkey has made buying one on arrival unreliable.
The good news first: this is a solvable problem, and the solution costs nothing. It just has to happen before you board.

What Turkey actually blocks
On 10 July 2025 Turkey's telecoms regulator, the BTK (Bilgi Teknolojileri ve İletişim Kurumu), began blocking international travel eSIM providers at network level. The first decision covered eight storefronts: Airalo, Holafly, Saily, Nomad, Instabridge, Mobimatter, Alosim and BNESIM.
The list has grown since. By May 2026 independent trackers counted 23 blocked providers, adding Jetpac, Maya Mobile, Roamless, GoMoWorld, Yesim, GigSky, Flexiroam, Airhub, Sim Local, Keepgo, Roamify, eTravelSim, Ubigi and RedteaGo. Some counts now run past 30. The BTK has never published an official list, which is exactly why no article — including this one — can promise you a current one.
The block targets provider websites and apps when you reach them from a Turkish network. It does not block eSIM as a technology, and it does not switch off a profile that is already running. The distinction is the whole story.
What still works
- An eSIM you activated before arriving. It connects to Turkish carrier networks and carries data normally.
- Everything you already downloaded. The profile lives on your phone, not in the app.
- A local Turkish SIM card. Sold normally, with passport registration.
What does not work from inside Turkey is everything that needs the provider's servers: buying a plan, activating a new profile, topping up data, or reaching support. If you run out of data mid-trip, you are on hotel Wi-Fi — which may block the same sites.
The rule that works for every provider
- Buy your eSIM at home, before you travel to the airport.
- Install and fully activate the profile while you are still on a network that is not Turkish. Do not leave the QR code for later — if your provider sends it by email, save the image to your phone.
- Buy more data than you think you need. This is the part people get wrong. Topping up inside Turkey is the thing that does not work, so a plan that runs dry on day six is a real problem.
- Check it works before you leave home. Switch the eSIM on and load a page. Finding out at passport control is too late.
In most countries an underestimated data plan is a minor annoyance: you open the app and buy another gigabyte. In Turkey that step is the one that is blocked.
For a two-week trip with maps, messaging and the occasional video, plan for roughly double what you would normally book.
Why we don't name a provider that 'still works'
Search for this topic and you will find plenty of articles naming one provider that is supposedly unaffected. Look at who published them: in almost every case, the company selling that provider.
We are not going to repeat that. The block list grew from eight to twenty-three in ten months and is not published officially, so any claim of the form "provider X still works in Turkey" has a short shelf life and no independent source behind it. Recommending one on that basis would be guessing with your holiday.
This also applies to the providers we link to elsewhere on this site. Airalo, Holafly and Yesim are all on the blocked list. They still work in Turkey if — and only if — you set them up before you arrive. That is what the rest of this article is about, and it is why we are not calling any of them the 'most reliable choice for Turkey'.
The local SIM alternative
Turkish carriers — Turkcell, Vodafone Türkiye and Türk Telekom — sell prepaid tourist SIM cards at the airport and in city shops. You need your passport: registration is mandatory and done at the counter. Coverage is excellent, and nothing about the eSIM block applies.
The trade-offs are the usual ones: your home SIM comes out of the phone, tourist tariffs are priced for tourists rather than locals, and you spend part of your first hour in a queue instead of on your way. For trips of a week or more where you would rather not think about data at all, it is still a reasonable option.
The 120-day rule nobody mentions
Here is the part that surprises people, and it only applies if you use a Turkish SIM card. The moment a foreign phone connects to a Turkish network with a local SIM, the device's IMEI is logged and a 120-day clock starts. After that, an unregistered foreign phone can be blocked from Turkish networks entirely — calls and data gone, emergency numbers only.
120 days is roughly four months. A two-week holiday, a month-long trip, even a long summer — none of them come close.
It matters if you spend a winter in Turkey, return repeatedly on the same device, or move there. Registration then requires a passport and a fee that is re-set every year and has climbed steeply; check the current figure with the BTK rather than trusting any article, including this one.
Using a travel eSIM instead of a Turkish SIM avoids the question entirely.
In short
- Turkey blocks eSIM shops, not eSIM data. Since 10 July 2025, growing to 23+ providers by 2026.
- Set up your eSIM before you fly — buy it, install it, activate it, test it.
- Over-buy your data. Topping up in-country is the step that fails.
- Ignore anyone promising a provider that is immune. The list is unpublished and moving.
- A local SIM works, with your passport and a queue.
Status as of September 2026. Turkey's restrictions have changed several times since July 2025, and they will change again — check the situation shortly before you travel.
