It is essential that "Data Roaming" is enabled in order to use the eSIM.
You can turn "On" and "Off" your Data Roaming in your settings.
Turning on your Data Roaming will allow any eSIM to work with your device.
To do this, follow these steps:
1. Go into Settings.
2. Click on "SIM cards & mobile networks"
3. Scroll down until you see the option "Advanced settings"
4. Tap "Data roaming"
5. Simply press the slider.
Accept the prompt that has appeared. If the slider is coloured blue then Data Roaming is activated. If it is white, Data Roaming is deactivated.
