Detailed Review
The Ubigi terms say the eSIM and the services are provided by Transatel S.A.S. or one of its affiliates, that Ubigi is a Transatel trademark, and that French law and the courts of Paris apply. The website describes Ubigi as a brand of Transatel and NTT.
Besides travel data, the same brand serves connected cars from several manufacturers and has a separate business site with its own pricing page.
Operator, not reseller
Transatel is a mobile operator, and Ubigi sells data directly on its own platform. The terms still say services may come from affiliates, so the exact legal entity can depend on the country where the eSIM is used or bought.
Device coverage
The site has installation guides for iPhone, iPad, Android and Windows 11, using a QR code or the Ubigi app.
No refunds on data plans
The terms state that once a data plan is purchased it cannot be refunded, although you can cancel a subscription at any time. That is stricter than sellers that offer a refund window.
Limitations to Consider
Consumer prices were not visible on the pages reviewed, so cost comparison needs the store. Data plans cannot be refunded once bought. The terms allow affiliates to provide the service, and the Ubigi brand also serves cars and enterprise buyers, so the consumer travel store is only one part of the site. The parent group is Japanese (NTT), though the contracting party named is French.
Who Should Use Ubigi
Travellers who prefer a mobile operator under French law, and people already using Ubigi in a car or at work.
