What it does well

Firsty centres on one eSIM and one installation that stays active at home and on every trip. There is nothing to swap on landing, which keeps repeat travel simpler. Data can be unlocked by watching a short ad for everyday essentials such as maps, messaging, socials and browsing. GB selections and day or month selections add flexibility for heavier travel periods. Calling to more than 200 countries adds another useful layer for staying in touch abroad.
