eSIM Firsty pour United Kingdom en 2026

No operator names are published for United Kingdom, so Firsty’s radio side is unknown rather than bad; the table above is where to check the allowances and validity that can actually be compared. Its large range makes sizing the real decision, with the risk of buying more data than a fortnight needs, while 5G is the fastest technology Firsty lists, not a promise for every handset or location. Firsty states that top-up is supported, so an exhausted plan can be extended rather than necessarily rebought. It has not published where traffic breaks out, leaving local latency and apparent IP location unspecified.
