eSIM Firsty pour Montenegro en 2026

Firsty has not published which operators it uses in Montenegro, so its radio-side reach is unknown rather than necessarily poor. It has also not stated where traffic breaks out, leaving local latency and apparent IP location unclear; its fastest published technology is 5G, an upper limit rather than a promise. With a large range of plans, the main choice is sizing data to the trip and avoiding more than a fortnight needs. Tethering is stated as supported, so a laptop can use the connection, while Firsty does not say whether voice is available.
