eSIM Firsty pour China en 2026

Firsty has not published which operators it uses in China, so its radio-side reach is unknown rather than evidence of a gap; the practical checks are the plan details shown above. Its China catalogue spans a large range, making data sizing the main choice and creating a risk of buying more than a fortnight needs. 5G is the fastest technology it lists, not a guarantee of service. Top-up is stated as available, so an exhausted plan can be extended rather than automatically rebought.
