KnowRoaming sits in the competitive middle of the eSIM market. Neither the cheapest nor the most feature-rich, they occupy a space that rewards execution over flash. Our testing aimed to determine if the tradeoffs make sense for most travelers.
The short version: KnowRoaming scores 3.9/5 in our comprehensive testing across 135 countries. They work well for travelers who prioritize sim sticker option, though there are providers that beat them on pure value or coverage breadth.
The longer version requires nuance. Both SIM sticker and eSIM options, which is genuinely useful in practice. But app feels outdated, and in a market where alternatives are improving monthly, that matters more than it used to. We evaluated KnowRoaming across multiple destinations, verifying pricing and coverage against official provider data.
The app is functional without being remarkable. You can buy plans, track usage, and manage your account. It works, which is more than some competitors manage, but it will not win any design awards.
