Which carriers matter, what buying a SIM involves, and when an eSIM is the smarter move.
Reliable mobile internet at better prices than most travel eSIMs, with polished iOS and Android apps and support for making and receiving phone calls.
One of the biggest travel eSIM brands, with a very large destination catalog.
Known for unlimited-data plans in many destinations, at a higher price per gigabyte.
Turkey blocks foreign phones after about 120 days of use with a Turkish SIM or eSIM, counted from the first time the handset connects with a local SIM. Registering a phone to lift the block costs 54,258 TRY in 2026 and is only realistic for residents, and the old dual-SIM trick of restarting the clock on a second slot no longer works. On a normal short trip none of this affects you. Separately, a prepaid SIM left without top-ups goes incoming-only after 180 days and is permanently cancelled at 270.
Strongest nationwide coverage, including rural and eastern Turkey. The usual first pick for travelers.
Cheapest tourist pack observed at Istanbul Airport, with solid coverage in cities.
Fine in cities and coastal resorts. Getting a tourist line involves a form and in-store pickup.
A passport is required for every prepaid SIM purchase; tourist packs are sold only when opening a new prepaid line with a foreign passport. A new SIM can also only be bought within 90 days of your last passport entry stamp.
Substantial. Airport counters charge roughly 1.3 to 1.7 times the official price: a pack that officially costs about 1,500 TRY starts at around 1,935 TRY (data-only) to 2,550 TRY and up at Istanbul Airport.
Guac eSIM covers Turkey with data plans starting from $1.50 per GB and instant activation, so your phone is online the moment you land. Airalo and Holafly are popular alternatives.
