Is my phone compatible?
Most failures come down to carrier lock, not the phone model — check yours first, it takes 5 seconds:
- iPhone: Settings → General → About → look for "No SIM restrictions."
- Android: Settings → About phone → dial *#06# — an EID number means your phone has eSIM hardware.
Most flagship phones from 2019 onward support eSIM — iPhone XS and newer, Google Pixel 3 and newer, recent Samsung Galaxy S/Note/Z models.

Thailand + Vietnam + Cambodia eSIM
This regional plan keeps you online across Thailand, Vietnam, Cambodia and a dozen more Asian countries, so multi-country travellers don’t juggle a new SIM at every crossing. Match the data and duration to your pace — three weeks of island-hopping and temple-touring burns more data than you’d expect. (Adding Laos? That leg needs a separate Laos-capable plan — see our Vietnam + Laos page.)
