Best eSIM for Turkey 2026: prices, networks & our pick

If you have an EU mobile plan, you can use it in France, Italy or Spain at domestic prices – but NOT in Turkey, which is outside the EU roaming zone. With a UK, Swiss, US or other non-EU plan, the EU rules do not help you there either. For calls and mobile data, your operator's (often expensive) roaming rates apply – without a travel add-on, you are billed per MB or even per 50 KB, depending on the operator.

That is exactly why a travel eSIM is particularly worthwhile in Turkey. Compared with roaming on your home plan, the savings quickly add up to a considerable sum.

For a classic 1–2 week holiday using 5–10 GB, Saily and Airalo are practically level: 10 GB for 30 days costs $15.99 at Saily and $15.50 at Airalo, 5 GB for 30 days $9.99 and $10 respectively.

If you only need a little data (maps, WhatsApp, the occasional email), Saily's small packages will serve you well: 1 GB for 7 days costs $3.99, 3 GB for 30 days $6.99. Airalo charges $4 for 1 GB, but that package is only valid for 3 days.

For streaming, video calls and content uploads, unlimited is worth considering: Airalo charges $24.50 for 7 days and $39 for 15, Holafly €25.50 for 7 days and €46.90 for 15. Yesim stood at €26 for 7 days and €43 for 15 (as of July 2026) – we were unable to re-check these prices in October.

Turkey's three major networks are Turkcell, Vodafone Turkey and Türk Telekom. Turkcell is traditionally regarded as the network with the best coverage – including inland and in mountain regions.

Before you buy, it is worth checking which network the eSIM provider uses: according to the providers, Airalo connects to Türk Telekom and Holafly to Turkcell and Türk Telekom (TT Mobil), while Yesim names Turkcell and Vodafone Turkey. Saily does not name its networks. In Istanbul, Antalya, Side and on the Aegean coast, all three networks perform well – off the tourist trail, Turkcell makes the difference.

Make sure you buy and install the eSIM at home on Wi-Fi: since July 2025, the Turkish telecoms regulator BTK has been blocking the websites and apps of many eSIM providers (including Airalo, Saily, Holafly and Nomad) on Turkish networks, and the block is still in place (as of October 2026). eSIMs that are already installed work normally; with most providers, the validity period only starts once the eSIM connects to a network in Turkey.

Buy a little too much data rather than too little: topping up via the app or website may fail because of the block once you are there.

Dual SIM keeps your home number active for WhatsApp and bank codes sent by text message – data runs over the travel eSIM, so switch off mobile data on your home SIM.

Important: explicitly turn off data roaming in the settings for your home SIM, otherwise your phone will fall back on expensive roaming after all when the eSIM signal is weak.
