BTK Ban: Does eSIM Still Work in Turkey?

edit Editorial team · updated 11 Aug 2026

Did Turkey ban eSIM? Short answer: no — it blocked the sellers' websites

Turkey did not ban eSIM. On 10 July 2025 the telecoms regulator BTK blocked the websites and apps of roughly 52 international eSIM providers — Airalo, Holafly, Saily, Nomad and dozens more — across three decisions through September 2025. The block sits on the vendor’s storefront, not on the connection. A profile bought and installed before you land keeps working; only reaching the seller’s site or app from inside Turkey is cut off.

Two different problems get folded into “eSIM doesn’t work in Turkey anymore,” and this page exists to keep them apart. One is BTK blocking a company’s website and app so a Turkish connection can’t load them — that’s what this page covers, and that is what leaves the Airalo app not loading once you are in the country. The other is Turkey’s device-registration regime, which can cut a physical phone off Turkish networks by its IMEI number and has nothing to do with which eSIM app you used. Every case of it we have found involves a resident or a long-stay visitor. A holiday-length trip on an eSIM bought before you flew is touched by neither.

The community worked out the fix independently across dozens of threads and states it in one line: buy and activate before you land . So does eSIM work in Turkey today? Yes — install before you land, and none of this touches your trip. That is the operating rule. The rest of this page is why it works, which providers still work, and the one place it stops working.

Which providers are blocked, and as of what date

BTK — Turkey’s telecoms regulator, the Bilgi Teknolojileri ve İletişim Kurumu — does not publish its own blocklist, and has refused freedom-of-information requests about it ( Diken, 10 September 2025 ). The record below comes from İFÖD/EngelliWeb, the tracker run by the İfade Özgürlüğü Derneği (Freedom of Expression Association), cross-checked against Turkish press.

That’s roughly 52 domains across three decisions of what press shorthands as the July 2025 ban. English-language coverage in 2026 still says “30+” — a figure that stopped counting after wave one. One caveat, stated rather than hidden: İFÖD’s third-wave list re-lists esims.io, already named in wave two, without explanation; we report the counts as published, not deduplicated by us.

Two details are worth reading past the number. CMLink (China Mobile’s international arm) and Ubigi (Transatel/NTT) both sit on the wave-two list, so the block reaches operator-backed services too. And it is not aimed at foreign firms as such. Days after wave one, the founder of eSIM.io — a product of the Turkish tech company Teknasyon — said his app had been caught by the same decision ( LOG, July 2025 ). İFÖD’s card for that wave does not list it among the 13, so we flag the mismatch rather than resolve it. Either way, a Turkish registration is no protection: BTK is blocking a category of service.

BTK has never published its grounds. İFÖD’s decision cards record the issuing unit as the Yetkilendirme Dairesi Başkanlığı, the Authorization Department — not the unit that handles Law 5651 content takedowns. Turkish press reported the platforms as having supplied mobile service to individuals without a licence, under Law 5809 ( Anlatılanın Ötesi, 11 July 2025 ). That reads as a licensing case rather than a content or data-localization rule, but BTK has not said so. Prof. Yaman Akdeniz, İFÖD co-founder and the person who runs EngelliWeb, put it plainly to Diken.

“BTK keyfi ve hukuka aykırı kararlarla eSIM sağlayıcılarına erişim engellemeye devam ediyor.” — “BTK continues to block access to eSIM providers through arbitrary decisions that violate the law.” — Prof. Dr. Yaman Akdeniz, İFÖD, quoted in Diken, 10 September 2025

Why your profile keeps working while the app does not

The whole scenario is roaming profile vs vendor website. An installed profile and a provider’s website sit on two different layers, and BTK’s decision touches only one. Once installed, your phone connects directly to a Turkish network (Airalo’s Turkey plans roam on Türk Telekom) as ordinary roaming traffic that never passes through the provider’s site or app. The block instead targets the vendor’s domain at the ISP level, the same DNS/IP mechanism used against any blocked site, aimed at ~52 eSIM domains. Reinstalling after landing doesn’t help: the site is gone from view, but the connection your phone already negotiated is not. The profile works, the app does not — as one r/AskTurkey exchange put it, “only eSim sites are blocked. If you have an eSim, you can continue using it” (u/postexitus, 24 December 2025 ).

A trip report written days after the first wave states the same misconception and corrects it in the author’s own words.

“Before my trip, I saw a lot of confusion online about eSIMs in Turkey. People were saying they don’t work anymore, but that’s not really true. What’s actually happening is that Turkey blocked the websites and apps of many major eSIM providers if you’re already in the country. [...] I bought and activated mine the night before I flew, and it worked fine the whole trip.” — u/FastRegret, r/istanbul, 30 July 2025

The rule held up over more than a routine trip. One traveller who first asked in August 2025 came back to the same post twice to confirm it still worked: once in February 2026, and again a month later.

“P.S: I did buy prior to entering Turkey then (Now Feb 2026) and it worked. Also did it a month ago, and worked again.” — u/JustSoni, r/eSIMs, 9 August 2025, updated February 2026

Four other threads state the same fix independently: u/mrskeptical00 (r/eSIMs, 9 August 2025), u/Few-Interview-1996 (r/AskTurkey, 17 November 2025: “Even the blocked esims work — if you activate them before arriving in Turkey”), and u/jxoch and u/ignas04 (both r/istanbul, 23 January 2026). Three subreddits, August to January, one rule. The app stays dark; data still connects.

You cannot top up from inside Turkey — what to do about it

No seller explains this. Run out of data inside Turkey and you can’t buy more from a blocked provider, because their storefront is exactly what’s unreachable. One community member worked through the whole chain in a single comment.

“The eSIM will work, just the app won’t. So you would have to buy the eSIM and load it on your home [wifi] before you land in Istanbul. [...] The issue with this is that if you run out of data then you won’t be able to top up, at least not without a vpn.” — u/VPrime, r/istanbul, 23 January 2026

The shape of the trap depends on how the plan is priced. Airalo’s Turkey packages are sold in fixed day-tiers — 3, 5, 7, 10, 15, 30 days — with unlimited data inside that window ( airalo.com/turkey-esim , checked 10 August 2026). The wall there is running out of days, not gigabytes. Other blocked providers sell fixed-GB packages, where the wall is a cap a heavy week of maps and video can hit early. Either way, fix it before the wall. Buy on the high side before you fly: a day-tier with a buffer past your return date, or a GB-tier one size up from a light week. There’s no shop to walk into once you land.

Ran out of data / the app will not open — what actually works now

Two options come up, and neither is a real fix. They are workarounds for a mistake that is cheap to avoid and expensive to undo mid-trip.

A VPN, briefly. The community’s fix is a VPN to reach the app for as long as it takes to buy the top-up, then off again. It treats the symptom, not the cause — without one you cannot top up inside Turkey at all.

A provider not on the list. Not every seller is blocked. BTK’s three decisions name roughly 52 domains, not the whole market. Check any candidate against the dated blocklist above first, because the reports disagree. One user in January 2026 named Mobimatter as working, and said they had topped up inside Turkey.

“Mobimatter works, I always use that one [...]. You can also buy more in turkey, this one isnt banned, used it recently.” — u/billbillieor, r/istanbul, 24 January 2026

Mobimatter is on the wave-one blocklist BTK issued on 10 July 2025. We’re not resolving that conflict here — either this report describes a workaround (VPN, mobile data vs. wifi) rather than open access, or enforcement lapsed since the decision. Treat the official record as the default and any claim it’s reopened as unverified until you check it yourself.

This is not the other blockage

Everything above is one kind of block: BTK cutting a company’s website and app off Turkish connections, never touching a profile installed before arrival. A second, unrelated regime blocks the device instead, and the two get confused constantly.

Turkey’s device-registration regime can shut a phone off every Turkish network by its IMEI number — the handset itself, not the eSIM app on it. Every reported case we have found involves someone living in Turkey or staying for months, not a two-week trip. What starts the counter is genuinely disputed, and this page does not settle it.

If that is what you are actually asking about, this is a different blockage — the fee, the 120-day window and the points where the sources contradict each other all live there.
