Do I need a Wi-Fi or cellular connection to install my Ubigi eSIM profile?

Yes, you will need an active internet connection—either via Wi-Fi or a cellular data network—before installing your Ubigi eSIM profile.

This connection is required when you scan the QR code provided by Ubigi and click the “Sign Up” button in the email you received. The connection allows your device to download and activate the eSIM profile properly.

We recommend using a stable Wi-Fi network if possible, as this can speed up the installation process and help avoid potential interruptions during the download. Once the eSIM is installed, you will be able to use your Ubigi data plan according to the plan’s coverage and validity.

Worked perfectly in Paris. No complaints!
I recently bought Ubigi for the first time for a week in Paris. No glitches, it worked seamlessly and was invaluable for navigating the city on foot. The connectivity, speed, and usefulness exceeded my expectations - and so easy to use. I would recommend to friends and family.

Perfect for New York
I used this eSIM during a trip to New York City. I have absolutely no complaints: everything worked perfectly, with no unexpected charges. Installation and management through the app were straightforward, and I experienced no issues with network coverage or connectivity.
