TormyrCousland Do you have 2 SIM cards installed in your phone? If so, can you remove the other SIM card once?
Please check the settings of the SIM. If they are ok, look for the app “SIM Toolkit” or “SIM” on your phone. Start the app and check if you can find something like roaming and make settings.
Alternatively, you can insert your SIM card into another device and test it. If you have reception and data traffic, it is due to the settings of your phone.
SIM Settings: SIM card manager (dual SIM models)
- Launch the Settings app and tap Connections → SIM card manager.
- SIM cards: Activate the SIM card to use and customise the SIM card settings.
- Preferred SIM card: Select to use specific SIM cards for some features, such as voice calls, when two cards are activated.
- More SIM card settings: Customise the call settings.
Greetings
