Roamless

Roamless operates as a no-commitment carrier, charging only for data consumed during your trip with no mandatory minimum spend or forced subscription terms. You activate the eSIM when you arrive and disable it when you leave, paying only for days used. Thailand coverage includes 3, AIS, and Dtac roaming partners.

Good fit for unpredictable travelers or those taking multiple short trips across a year. Less suitable if you want speed-guaranteed unlimited plans, but the pay-as-you-go model appeals to budget travelers who prefer zero lock-in and month-to-month flexibility.
