トルコ向けおすすめeSIM

Turkey registers foreign phones as soon as they connect using a Turkish SIM. After roughly 120 days the handset is blocked until a fee of about €150 is paid. A two-week holiday never reaches that point, but it matters if you visit often, stay longer, or carry a second device.

A travel eSIM sidesteps it entirely — it works through roaming agreements rather than a locally issued SIM. That's the practical reason an eSIM is worth more here than in most destinations.

Three GB comfortably covers a week in Istanbul: maps, messaging, uploading photos, the occasional video. A road trip with navigation running all day is closer to 1 GB per day. Working remotely or tethering a laptop doubles it.

Prices in the table above are live and re-checked daily. The calculator below asks how long you're travelling and how you use your phone, then shows the cheapest plan for that specific trip — not the best price per GB, which on short trips is almost never the same plan.

Install the eSIM at home while you have Wi-Fi: the QR code needs a connection to set up, and free Wi-Fi at Istanbul airport is capped at 60 minutes. Most plans start counting when the first byte is used, not at purchase.
