Our verdict
Airalo wins for general travel: a better app, broader catalog, and prices that match or beat Ubigi on most routes. Ubigi wins where the network is the point: its NTT/Transatel infrastructure makes it our pick for Japan, and its connection stability and monthly recurring plans suit frequent business travelers who want one eSIM that simply stays configured. Tourists take Airalo; Japan-bound and stability-first travelers take Ubigi.
“The default choice for a reason: more countries than anyone, a mature app, and fair prices. Not always the absolute cheapest per gigabyte, but the combination of coverage, reliability, and ease keeps it on top of our shortlist.”Editorial team, on Airalo
“The network-grade option: Ubigi is run by Transatel, an NTT company that actually operates mobile infrastructure. Connections feel carrier-stable, Japan coverage is best-in-class, and it works in cars and laptops too. The app is more utilitarian than the startups.”Editorial team, on Ubigi
