You know better. People buy "safe" phones with a price much more sabzh. Whose filling and 100 bucks are not worth it.
Investigated commands transmitted from the SIM card to the phone? What do they contain? Until you filter this traffic, the phone will not be safe.
The computer connected to the network by RJ45 or Wi-Fi - becomes part of the network.
The phone connected to the network becomes the same part of the network. It doesn't matter if there is a sim card in it or not. 112 and 911 are called. So you are online. If you can call on one side, it means that you can call you on the phone. And the call is the connection = network.
Do you think CTOTO will filter all this traffic? They have nothing in the technical task (or business plan as I do not know) anything does not seem to say about it.
