Keepgo

Keepgo simplifies travel with data plans that don't expire, letting you load credits once and use them whenever you need. Coverage spans over 100 countries, so you're never locked into country-by-country SIM swaps. It's ideal if you travel frequently or in unpredictable patterns, since your balance carries over indefinitely.

The app tracks usage and lets you top up data easily. Rates vary by destination, but the non-expiring model suits travelers who take irregular trips.
