SIM authentication is a great way to add an additional layer of security to the SIM connection process, and prevent unauthorised access or usage.
To enable or edit SIM authentication, first check What are the SIM capabilities? to ensure the MNO supports the feature.
Then take the following steps:
- Navigate to the SIM Details page of the required SIM.
- Click the "Enable SIM Authentication" switch.
- The following is displayed.
- Enter the desired username and password and click 'Save'.
This username and password will now be required when the device attempts to authenticate on the private APN.
