I travel internationally infrequently (1x/year in the summer) and have always relied on WiFi but now feel like a small amount of data (eg. 500MB) would make my trips a bit smoother.

However after hours of research I’ve had a hard time finding travel SIMs that won’t expire before my next trip (for example any data packages purchased with KnowRoaming, SurfRoam, etc would all expire by the time of my next trip and would make no sense considering my low needs).

Any advice for me? I wouldn’t mind buying a bigger data package as long as it lasts for at least a few years...
