I've been using Ubigi for two years for my business trips. Setup is so simple, and I get internet access within seconds upon arrival. Prices remain reasonable and support helped me quickly once when I had a problem.

Excellent app, really user-friendly. On my last trip to Japan, I bought and installed the eSIM directly from the app before takeoff. Connected upon arrival, it was perfect for navigation and using transport.

Practical and flexible service. You can buy packages for one day or a month depending on needs. I especially appreciate real-time consumption tracking and the ability to top up easily from anywhere.

Good platform but I experienced slow speeds at times in some countries. Support is responsive, luckily. In my opinion, it’s a good choice if you accept that speed may vary depending on location.

I travel constantly and Ubigi lets me stay connected without worry. Regional plans are excellent for covering multiple countries at once. Highly recommended for long-term travelers.

Description

Ubigi is the leading eSIM solution developed by Transatel-NTT for travelers, digital nomads, and professionals on the move. With presence in over 200 destinations across 5 continents, Ubigi offers local, regional, and global plans tailored to every travel need. Activation is instant, the app is intuitive, and customer support is available 24/7. Ideal for avoiding exorbitant roaming fees and staying connected everywhere, hassle-free.

How it works

Go to the App Store (iOS) or Google Play (Android) and download the official Ubigi app. The app is free and available in multiple languages.

Launch the app and sign up with your email address. You can also use Apple ID or Google sign-in to simplify the process.

Select the country you are traveling to or the region if covering multiple countries. The app shows all plans available for that area.

Choose the data volume (500 MB, 1 GB, 10 GB, etc.) and validity duration (1 day, 7 days, 30 days, etc.) that matches your trip.

Pay using accepted methods: bank cards (Visa, Mastercard), PayPal, Apple Pay or Google Pay.

The app generates a QR code or offers direct installation. Follow instructions: go to Settings > Cellular Data > Add eSIM and scan the QR code or confirm installation.

Once at your destination, go to Settings > Cellular Data and ensure Ubigi eSIM is set as your active line for mobile data. Also enable roaming if necessary.

⚠️ If it fails

✅ Check that your phone is eSIM compatible (recent models only). Ensure you have a stable Wi-Fi connection during installation. Restart your phone and relaunch the app. Contact Ubigi support if the problem persists.

✅ Check that Ubigi eSIM is activated in settings (Cellular Data > Select Ubigi). Turn airplane mode off and on. Try a full phone restart. Contact support via in-app chat with your exact location.

✅ Check your real-time consumption in the Ubigi app. Disable automatic updates and high-resolution video playback. Stop data-heavy apps running in the background. Consider purchasing a larger data package next time.

✅ This may be due to local partner networks. Try manually switching to another network (if available) in Settings. Contact Ubigi support who can verify coverage in your exact area and suggest solutions.

FAQ

For a one-week stay in Europe, you have two options: a plan specific to the main country (e.g. 10 GB for 7 days in France) or a regional Europe plan if visiting multiple countries.

Check the general conditions or contact support to know exact terms and timelines (usually 10 business days after approval).
