How we score
This score is eSIMrat's own, not an average of customer reviews. It covers six criteria we assess ourselves from the catalogue's real coverage, the prices we record, and test purchases and installs. We earn a commission on sales made through our links: it changes neither the score nor the order of our rankings, which stay sorted by price per GB.
The eSIMrat verdict
Ubigi is the eSIM of a real operator, Transatel, part of the NTT group, and it shows in the mechanics: automatic activation on arrival, top-up from the app without reinstalling a profile or needing Wi-Fi, tethering allowed, euro pricing. The price per GB is well placed, especially on large volumes. The weak spot is support: a form and a help centre, no live chat, and reviews describing dropouts that had to be fixed by hand on some destinations.
Good for
- Frequent travellers: one eSIM kept and topped up from trip to trip
- Large volumes: up to 200 GB, plus unlimited
- Anyone paying in euros who wants a fixed price
- Long stays: plans up to 360 days
Less suited if
- You want live chat at any hour (→ Airalo, Saily)
- You need native calls or texts (→ Yesim, Sim Local)
- You want the lowest price per GB on a small plan (→ Esimzon, Roamify)
- You want human support 24/7 with excellent value for money, an eSIM that is simple to install and an easy-to-use app (→ voilà eSIM)

How to install your eSIM with Ubigi
Buy your plan
Download the Ubigi app (iOS or Android) or order on cellulardata.ubigi.com: plans are bought and topped up from the app.
Pick your destination
Choose your destination and your data plan.
Scan the QR code
Pay and scan the QR code to install the eSIM.
Get connected
Turn the connection on when you land. That's it.
If something goes wrong
Check that your phone is eSIM-compatible and unlocked, then install from the Ubigi app or by QR code over a stable Wi-Fi connection. Ubigi's help centre has step-by-step guides and video tutorials; if it stalls, the contact form sends your request to support.
Turn Airplane mode on and off again. Check that the eSIM from Ubigi is selected for mobile data in your settings. Turn data roaming on. Restart the phone. If nothing changes, switch network selection to manual and pick another operator.
Look at per-app usage in your phone's settings to spot the hungry apps. Turn off automatic updates and high-resolution video playback. Your remaining data shows in your Ubigi account, or in its app when there is one.
Open the Ubigi app: the purchased eSIM installs from there without a QR code. If you ordered on the site, check your spam folder, then use the help centre form for a resend.
