eSIM Roamless pour Guernsey en 2026

A dozen or so plans make sizing the real decision in Roamless’s Guernsey catalogue: the risk is buying more data than a fortnight actually needs. Roamless has not published which operators it uses here, so the radio side is unknown, and it has not stated where traffic breaks out; local delay and apparent IP location cannot be inferred. Its fastest stated technology is 5G, not a guarantee of what a handset will show. Top-up is supported, so an exhausted plan can be extended rather than immediately rebought; Roamless does not say whether it provides a phone number.
