Your troubleshooting guide to setting up your Mozillion Travel eSIM on Windows 11
Check on this list if your device is compatible with Mozillion Travel eSIM services.
If your device is compatible with Mozillion Travel eSIM services, it must be equipped with an eSIM or a physical SIM card.
1
Check eSIM Profile Installation
Your device is equipped with an eSIM:
Check now if an eSIM profile is installed on your device. Go to: Start > Settings > Networks & Internet > Cellular > eSIM Profiles.
At the top of the page, you can see which SIM card/eSIM are installed on your device. Mozillion Travel eSIM profiles will be displayed as TSL-1234 (ex: TSL-0131, TSL-0199, etc.).
If you have a Mozillion Travel eSIM profile, click on the little arrow to display more options and click on use to select it (click yes on the displayed message).
1.2
If no Mozillion Travel eSIM profile is installed, please follow instructions here to install a Mozillion Travel eSIM profile.
Once the Mozillion Travel eSIM profile is installed, click on it to display more options and click on use to select it. After that, go to the next step.

Check eSIM Profile Activation
On the network flyout, ensure that:
Cellular (or Mobile) is Activated. Wi-Fi is Deactivated.
3.1
Apply Data to eSIM Profile
Now apply Mobile data to your Mozillion Travel eSIM profile:
Go to: Start > Settings > Networks & Internet > Cellular (or Mobile). In the drop-down menu at the top, choose the SIM corresponding to your Mozillion Travel eSIM profile to make sure you have selected the right one, you will see the name Mozillion displayed right under Connection settings with the cellular network bars.
3.2
Make sure that Roam is set on the Data roaming options:
Go to: Start > Settings > Networks & Internet > Cellular (or Mobile). On that same page on the Data roaming options field, select Roam in the drop-down menu.
Important: If you have carefully followed previous steps, your Mozillion Travel eSIM profile is now used for the cellular data connection (and NOT your physical SIM card if you have one). This means that you won’t have extra roaming costs as Mozillion Travel eSIM rates will be applied while using the Mozillion Travel eSIM cellular connectivity. In any case, always ensure that your Mozillion Travel eSIM profile is selected for cellular data to avoid extra roaming costs while abroad.
4.1
Check APN configuration
Now ensure that the APN (Access Point Name) is correctly set on your device.
Go to: Settings > Networks & Internet > Mobile, then Mobile Operator Settings.
If the Mozillion Travel eSIM APN “mbb” appears on the list under “APN Settings” section, go to the next step.
If the Ubigi APN “mbb”does not appear, click on “Add an APN” and fill in:
– Profile name: Mozillion– APN: mbb
Click on save. This new APN will appear in the “APN settings” list.
4.2
Make sure that the Mozillion Travel eSIM APN appears as “Applied”. If not click on it and select Apply.
5.1
Check Network Display
At this step, turn ON “Flight Mode” for 5 secondes and turn it OFF. This action will refresh the network connection from your device.
5.2
Once you are connected to the network, you will see a network icon appear on the bottom line.

Final Check
At this step, test your Travel eSIM connectivity by opening the network flyout and click on “View My Account”.
Or open a browser and go to mozillion.com/travel-sim
