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.)
