eSIM Roamless pour Thailand en 2026

dtac is the only operator Roamless names for Thailand, so the radio side is settled before you choose a plan: the differences here are allowance and validity, not signal. Its catalogue spans a large range, making data sizing the real decision and creating a risk of buying more than a fortnight needs. The fastest stated technology is 5G, though that is a ceiling rather than a promise. Roamless does not say where Thai traffic breaks out, so delay to local services and apparent IP location are unknown. Top-up is supported, allowing an exhausted plan to be extended rather than rebought.
