What is SIM authentication?

Follow

Some mobile network operators support the ability for a SIM to require the device to provide a username and password before it can be used.  This provides the ability for the SIM to only be used in the device, or devices, for which it was intended. There is the capability for users to change the username and password on a SIM from the default credentials to customised ones.

Please see our SIM capabilities matrix for the networks that support this feature.

Please follow this article to steps on how to update the SIM authentication.
