Firsty eSIM Plans for Tonga

Firsty has not published which operators it uses in Tonga, so the radio side is unknown rather than bad; its traffic breakout is not stated either, leaving local delay and apparent IP location unclear. The catalogue contains a single plan, so there is nothing to choose within Firsty: it fits the trip or it does not, and comparison is against other providers. Firsty lists 5G as its fastest technology, as a ceiling rather than a promise. It does say top-up is available, so an exhausted plan can be extended rather than rebought.
