Pick Airalo when the trip crosses borders. Its regional plans — Europe, Caribbean, Asia — pool data across dozens of countries under one profile, which no other provider here does as broadly. It's also the safest first eSIM: the app is polished and setup rarely goes wrong.
Pick Yesim when you'll burn serious data in one place. Its unlimited plans remove the meter for a week or a month, and the built-in VPN is genuinely useful on hotel and airport Wi-Fi. Less compelling for multi-country routes, where coverage gaps appear on smaller destinations.
Pick Saily when price per GB decides. Entry plans regularly undercut Airalo by 10–20% on popular destinations, and the ad-blocking/web-protection layer comes free. The trade-off is a smaller destination list and no unlimited tier.
Pick Drimsim as a second eSIM, not a first. Pay-per-MB pricing is expensive as primary data, but the balance never expires and one profile works almost everywhere — ideal insurance for the port or border town where your main plan has no partner network. Our cruise guide and USA + Caribbean guide show this pattern in action.
How we compare
Every comparison on this site uses the same criteria, in the same order: real cost per usable GB (not headline price), network partners at the destination (which local carrier you'll actually ride on), plan flexibility (top-ups, validity, expiry), hotspot policy, and setup friction. We re-check provider pricing periodically and date every page — if a number looks stale, the destination page always carries the latest.
For decisions between two specific providers, the head-to-head pages below go deeper than any table can: exact plan grids, coverage overlap, and a verdict for each trip type.
