Ubigi Alternatives
Ubigi is the connoisseur's pick: an NTT-backed MVNO that ranked fastest overall in a 2026 independent eSIM speed study, and is particularly strong in Japan and Korea.
Why people leave Ubigi
Speed leadership does not show up on a coverage map, and it does not help if your destination is not one where Ubigi holds a strong partnership. The brand is also less consumer-friendly than its rivals: it reads as a carrier product because it is one, and travellers who want a two-tap purchase sometimes find the experience more technical than Airalo's.
Why you might stay
If you are working from the road and a slow connection costs you real money, measured speed is the specification that matters most and Ubigi is the one brand here that competes on it. In Japan and Korea especially, it is the recommendation.

The Sherpa take
Do not leave Ubigi for a marginal price saving if you depend on the connection for work. Leave it if you are travelling somewhere it has no particular network advantage, where a cheaper reseller carries the same local operator.
