Firsty eSIM Plans for Thailand

Firsty has not published which operators it uses in Thailand, so the radio side is unknown rather than necessarily limited; the table above is the practical place to assess the available plans. Its fastest stated technology is 5G, although that is a ceiling rather than a promise at every location. With a large range of plans, the main decision is sizing your data allowance, since the risk is buying more than a fortnight needs. Tethering is stated as supported for getting a laptop online, while top-up can extend an exhausted plan instead of requiring a rebuy.
