eSIM Roamless pour Serbia en 2026

Roamless has not published which operators it uses in Serbia, so the radio side is unknown rather than bad; the table above is where the stated allowances and validity can be checked. Its traffic breakout is not stated either, so local delay and IP location cannot be inferred. The fastest technology it lists is 4G, a ceiling rather than a promise. With a large range of plans, sizing is the real choice, and top-up is stated as available if the initial allowance runs out.
