GOOD TO KNOW
AIS does not publish one fixed roaming price that we could verify — it depends on your plan and destination. We list 3 AIS roaming options on this page; follow the official link for the price on your plan.
It often is for trips of more than a few days, because a prepaid eSIM is one payment for the whole trip. Compare AIS's price for your plan with a Graba SIM plan for your destination.
Before you land, open Settings and turn Data Roaming off for your AIS line (iPhone: Mobile Service or Cellular; Android: SIMs or Mobile network). Turn off automatic data switching too. To avoid calls and texts being charged, turn the AIS line off or use Wi-Fi calling where AIS allows it.
Yes, on a dual-SIM phone. Keep your AIS line on for calls and texts with its Data Roaming off, and set the Graba SIM eSIM as your mobile data line. AIS may still charge for calls, texts and voicemail abroad.

HOW WE CHECK
The price, currency and how it is charged were read from the operator's own website on the date shown.
The operator explains its roaming rules, but not as one fixed price — for example, inclusive roaming that depends on your plan.
The plan exists, but its price depends on your contract or destination. Use the official link to see yours.
Recorded in an earlier research pass and not re-checked yet. We show the plan name and terms, never the old price.
A blank price means we could not verify one — never that it is free. Prices include or exclude tax as the operator publishes them. Snapshot: 25 October 2026. Logos are trademarks of their owners and identify each network only; Graba SIM is not affiliated with these operators.
