Travel eSIM Troubleshooting 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.

Step 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).

Step 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.

Step 2

Check eSIM Profile Activation

On the network flyout, ensure that:

Cellular (or Mobile) is Activated.
Wi-Fi is Deactivated.

Step 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.

Step 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.

Step 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.

Step 4.2

Make sure that the Mozillion Travel eSIM APN appears as “Applied”. If not click on it and select Apply.

Step 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.

Step 5.2

Once you are connected to the network, you will see a network icon appear on the bottom line.

Step 6

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

NB: In case you still have no network bars displayed, please contact our Customer Support for further help and provide the ICCID of your eSIM profile.
