Keepgo

The no-expiry data model is a genuine advantage for travelers with unpredictable usage. Buy more data than you think you'll need without worrying you'll forfeit the overage, and carry forward any leftover balance to your next trip. Keepgo also sells portable Wi-Fi hotspots alongside eSIMs if you prefer shared device connectivity.

This approach works well for frequent travelers or those taking multiple trips within a year, since unused credit genuinely carries forward.
