Which global eSIM provider has the best coverage?
Airalo, Ubigi, Saily, and KnowRoaming all claim 200+ country coverage, making them the broadest options. However, coverage quality varies by destination. Airalo and Ubigi publish specific network partners for each country, allowing you to verify coverage depth. For transcontinental travel, MTX Connect's 130+ country network often provides stronger coverage density in covered destinations.
