Which is cheaper for an eSIM — Thailand or Vietnam?

Which has better LTE coverage — Thailand or Vietnam?

Thailand runs primarily on AIS and DTAC. Vietnam runs primarily on Viettel and Mobifone. Both deliver strong urban coverage; rural penetration depends on the destination's terrain — see the country pages for full coverage maps.

Should I install my eSIM before flying to Thailand or Vietnam?

Yes — install at home on Wi-Fi for both. Activation deferred to first connection means the validity clock only starts when you land. There is no advantage to waiting until you arrive.

Will my phone work with both an Thailand and a Vietnam eSIM?

Any iPhone XS or newer, Pixel 3 or newer, and most modern Samsung Galaxy devices support eSIM. You can store both eSIMs on the same phone and switch between them in Settings without removing anything.
