Travel eSIM vs AIS eSIM
AIS's eSIM is a plan on AIS's own Thai network, built for use inside Thailand; a travel eSIM is built for use abroad, in many countries, without an AIS number or account.
What AIS's eSIM actually is
AIS's eSIM is simply AIS's own SIM format — AIS being a Thai mobile network operator — so it is built primarily for use inside Thailand. A travel eSIM from esimonline.asia is built specifically for mobile data while travelling abroad, covering many destinations through plans chosen by country.

Häufige Fragen
Can I use AIS's eSIM when travelling abroad?+
That depends on AIS's own international roaming terms — check with AIS directly before you travel. A travel eSIM, by contrast, is built for use abroad from the start.
If I install a travel eSIM, will my AIS number stop working?+
Yes, it keeps working normally. A travel eSIM is an extra data-only profile that runs alongside your primary SIM or eSIM — it does not replace it.
Is AIS's unlimited internet plan really unlimited?+
"Unlimited" domestic plans from Thai carriers like AIS are typically subject to a fair-usage policy (FUP): full speed up to a soft data threshold, then throttled to a slower speed for the rest of the billing cycle, rather than truly uncapped high-speed data. Our own travel eSIM plans, by contrast, are usually a fixed data allowance for the trip, with no speed throttling within that allowance. AIS's FUP terms can change, so check the current details directly with AIS before deciding.
