Frequently asked questions about eSIM in Thailand

Will my phone work with an eSIM in Thailand?

Most eSIM-compatible, unlocked phones released in the last few years will work in Thailand. Dial *#06# on your device and check for an EID number to confirm support before you buy.

When should I activate my Thailand eSIM?

You can install the eSIM before you leave home, then activate it once you land in Thailand so your validity period starts exactly when you need it.

Can I keep my home number while using a Thailand eSIM?

Yes. Your Thailand eSIM plan runs alongside your existing SIM, so you keep your home number for calls and texts while using local data.

What if my eSIM doesn't connect in Thailand?

First confirm your device is unlocked and eSIM-compatible, then check your network settings. If it still doesn't connect, contact our support team with your order number for help.
