Thailand eSIM — FAQ
How do I get an eSIM for Thailand?
Pick a Thailand data plan below, pay by card or crypto, and we deliver your eSIM instantly. Scan the QR code and you're connected in minutes — no physical SIM, no store visit.
Will my phone work with a Thailand eSIM?
Most phones from the last few years support eSIM, including iPhone XS and newer, Google Pixel 3+, and recent Samsung Galaxy S/Z models. Your phone must be carrier-unlocked.
Does the Thailand eSIM include 5G?
Yes — our Thailand plans connect to 5G where the local network supports it, and fall back to 4G/LTE automatically.
Which network will I connect to in Thailand?
Our Thailand plans use partner networks including AIS. Available networks depend on the selected plan, device and location.
Is there a plan that covers Thailand and other countries?
Yes. Asia, Global Lite, Global Max and Global are regional plans that include Thailand, which is usually cheaper than buying each country separately on a multi-stop trip.
Can I keep my own phone number?
Yes. The eSIM runs as a separate data line, so you keep your main number for calls and texts while using Thailand data on the eSIM.
When does my plan start?
Activation rules vary by plan. Check the activation note at checkout before installing your Thailand eSIM; some plans start on connection or first data use, while others have different activation rules.
