Firsty publishes 120 or more destinations.
Destination lists change and regional plans differ from country plans, so check yours against Firsty’s own coverage page before you install anything.
Our verdict
Not a trial so much as a permanent safety net. It carries messaging and maps and it will not carry a video call. Worth installing alongside a proper plan so you are never completely without data, rather than relied on as your only connection.
The catch: The free speed is heavily reduced. It carries messaging and maps, and it will not carry video. Paid tiers lift the speed.
