Roamless

Roamless offers a single global eSIM that works across 200+ countries with pay-as-you-go rates and credit that never expires. You only pay for what you use, whether you're checking maps for a day or staying for a month, and there's no need to swap between regional plans as you move around.

This model appeals to unpredictable travelers, frequent movers between continents, and anyone who dislikes watching credits vanish against an expiration date. The non-expiring credit means you can top up before a trip and use the remaining balance years later without losing money.
