Keepgo

Digital nomads who return to the same handful of countries every few months face an odd problem with most travel eSIMs: any data left over when a plan expires is simply gone, so buying a bigger bundle to get a better per-gigabyte rate can end up wasting money if the trip runs shorter than planned. Keepgo, operating since around 2011, solves that directly with a balance that doesn't expire, provided you connect to a network at least once every 360 days, letting unused data roll forward into your next trip instead of resetting to zero.

Coverage comes as regional bundles, a Global tier spanning about 102 destinations and smaller packs like Europe covering 30-plus countries, rather than granular single-country plans. Pricing starts near €2 for 100MB and scales into bundles over 100GB, all data-only. Letting the balance sit completely idle triggers a small monthly reservation fee rather than an outright expiry, and refunds apply within 30 days on an uninstalled eSIM minus a 10% fee. It's built for someone who travels internationally several times a year and doesn't want each trip's leftover data disappearing after 30 days.
