eSIM Firsty pour Serbia en 2026

No operator names have been published for Serbia: Firsty has not said which networks it uses, so the radio side is unknown rather than poor, and the checkable details are in the table above. Its catalogue spans a large range, making data sizing the main decision and raising the 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 rebought.
