Android 10 Q allows operators to prohibit the use of smart phones to specific cellular networks
With the release of the tenth version of the popular Android mobile operating system users will have access to various innovations like the global night mode, which will be used in all applications and the menu items.
However, there will be other innovations that, in particular, relate to advanced features for Telecom operators. Sources report that the operators will have more granular control over which devices will or will not be able to work in a network. They will be able remotely via a SIM card to ban smartphones with Android 10 Q access to a particular cellular networks.
You can define a list of permitted and prohibited operators, i.e. white and black lists of what will and will not work on your specific phone. This will allow you to block even network virtual operators that work using the same rigs as your main operator.
At the moment the operators can set individual restrictions for each slot for the SIM card, and with the release of Android Q it can, for example, to block the second slot if the first slot not allowed SIM card. The lock will be applied immediately and will persist after restarting the phone and even after reset.
Emergency phone calls will work after blocking.
