Ubigi
eSIMGlobal eSIM backed by Transatel (NTT)
Best for: Frequent flyers to Europe/North America, car connectivity users, and travellers who want a never-expiring set-and-forget eSIM or a monthly subscription.
Overview
Ubigi is a premium eSIM service operated by Transatel, an NTT Group company, with coverage in 200+ destinations. Strong in Europe and North America, it offers reliable networks, in-car connectivity partnerships and pay-as-you-go or subscription plans.
Ubigi's differentiator is telecom-industry depth: Transatel is a full MVNO operator inside the NTT Group, not a travel-tech startup, and it shows — Ubigi ships preinstalled in cars from Jaguar Land Rover, BMW and others, and its network agreements favour premium carriers in Europe and North America.
For travellers, the catalogue mixes day passes (from 500 MB / 1 day), 30-day bundles (1 GB to 50+ GB), regional Europe/USA/Asia packs, and monthly subscription plans (e.g. 10 GB/month recurring) aimed at frequent flyers and expat families — the subscription angle is rare among travel eSIM brands. Installation can start from the car dashboard or the Ubigi app/web account; the same account tops up across countries. Pricing sits in the middle of the pack: not the cheapest per GB, but the network quality in Europe (often multi-carrier) is consistently reported as excellent. Pay-as-you-go credit never expires, which suits occasional travellers who want a set-and-forget eSIM that stays valid between trips.
