The IMEI gotcha that doesn't apply to eSIMs
Türkiye has a rule about foreign phones that catches travelers off guard: register a foreign device on a Turkish SIM and after a few months it gets blocked unless you pay a steep IMEI registration fee. That's specifically for local SIMs sold to foreigners. A travel eSIM running on a foreign network sidesteps the whole thing — the phone roams on a foreign carrier's plan, the Turkish IMEI registry isn't involved, the eSIM keeps working as long as your balance does.
Roamzy charges $1.54 per gigabyte in Türkiye. That's $0.0015 per megabyte, billed in real time as your phone uses data on Turkish networks. No subscription. No expiry on the unused balance. No minimum bundle. One per-MB rate across 193 countries — that's the plain arithmetic of the bill, not a marketing line.
How much will Roamzy actually cost on this trip?
A typical visitor to Türkiye uses 0.5–1.5 GB per day: Maps from Sultanahmet to Beyoğlu, the camera-translator on a kebab menu, BiTaksi or Uber across Istanbul, the Pegasus or Türk Hava Yolları app, Yemeksepeti for late-night food, contactless payments, the occasional video call. Call it 1 GB/day for the math:
| Trip length | Roamzy ($1.54/GB) | Tourist roaming pass | Local SIM at IST |
|---|---|---|---|
| 3 days | $4.62 | $15–40 | $15–30 + IMEI registration trap |
| 1 week | $10.78 | $25–60 | $20–40 + paperwork |
| 2 weeks | $21.56 | $40–100 (often two passes) | $25–50 + IMEI risk on returning trip |
Competitor prices in columns 3 and 4 are 2025 ranges based on typical offerings; exact figures depend on your home carrier and the airport store you visit. Roamzy's rate in column 2 is our actual published rate from the pricing page.
A local SIM at IST or SAW is fine for a single short trip. For travelers who come back to Türkiye more than once a year, the IMEI lock kicks in and the same phone stops working on a Turkish SIM until the registration fee is paid. The eSIM avoids the question.
Why is per-megabyte pricing simpler than packages?
A Türkiye trip is already a stack of small things to think about: a currency that moves week to week, a city laid out across two continents, a transport map in Latin script you can mostly read, a card your bank flagged on the third lokum. The data plan should not also be a problem.
Roamzy is built around that. No first-purchase promo to lure you, then jacked rates. No fine-print throttling. No auto-renewal you forgot to cancel. One rate, billed by the megabyte, balance carries.
Where does Roamzy work in this country?
Türkiye is one of the better-wired emerging markets. The shape on the ground:
- Istanbul, Ankara, İzmir, Antalya, Bursa — 5G is rolling out in the major cities, with solid LTE everywhere
- The Aegean and Mediterranean coasts (Bodrum, Marmaris, Kaş, Alanya) — strong LTE through the resort towns
- Cappadocia (Göreme, Ürgüp, Avanos) — solid LTE in the towns; balloon valleys at sunrise have signal
- Pamukkale, Ephesus, Mount Nemrut — fine in the visitor zones, weaker on hiking trails
- Eastern Anatolia (Van, Erzurum, Kars) — workable in towns, patchy on the highways between them
- Istanbul Metro and Marmaray — continuous signal across the Bosphorus tunnel
Long-distance coach routes across central Anatolia hold signal for most of the way; mountain passes drop briefly.
How do I install my Roamzy eSIM?

Supported stablecoins, networks, and common iPhone/Android setup errors are in the FAQ.
What are Roamzy's honest limitations?
Three traps Roamzy doesn't have because they were never built in.
- No welcome promo that bait-and-switches your second top-up. The rate on top-up #1 is the rate on top-up #20.
- No fine-print throttling. One rate, full speed — first GB and the hundredth cost the same $0.0015/MB.
- No auto-renewal you forgot to cancel. Balance runs out, the eSIM stops.
At this price there's no room for theatre anyway. Metering Türkiye by the megabyte, with nothing expiring, is an engineering decision; marketing had no say in it.
What if my trip continues to other countries?
Türkiye is a hub between Europe and Asia. Same Roamzy account, same logic at the border:
- Greece — frequent extension via Aegean ferry or short flight
- Bulgaria — overland through the European border
- Georgia — overland from the east, common Black Sea route
