Keepgo

Keepgo stands out for plans that don't expire, making them ideal if you're planning repeat trips across Asia. The service bundles both eSIMs for phones and pocket WiFi devices, so you can choose whatever fits your travel style.

The lifetime-validity feature means you can keep your data balance across multiple trips without watching it vanish after 30 days. For digital nomads or frequent business travelers to Asia, that's a genuine advantage over standard expiring plans.
