  • Your phone connects to the AIS network, and you can start using maps, messaging, and travel apps as usual.

To use a UPeSIM eSIM in Thailand, your device needs to support eSIM technology and be unlocked.

  • An eSIM-compatible smartphone: Most recent iPhone and Android models support eSIM. Check your device settings or the UPeSIM compatibility list before purchasing.
  • An unlocked device: Your phone should not be locked to a single carrier, so it can accept a Thailand eSIM plan.
  • Internet connection for installation: You need Wi-Fi or mobile data to scan the QR code and download the eSIM profile.
