eSIM Firsty pour Spain en 2026

The operators Firsty uses in Spain have not been published, so its radio-side reach is unknown rather than necessarily limited. Its large range of plans makes sizing the real decision, with the risk of buying more data than a fortnight needs. 5G is the fastest technology listed, so it is a ceiling rather than a guarantee of what a handset will show. Firsty has also not said where traffic breaks out, leaving local delay and the IP’s apparent country unclear. Top-up is stated as supported, allowing an exhausted plan to be extended rather than rebought.
