Will communication work with a nulled IMEI on the phone?

Question

Information Security

There was an argument with a friend.
If I nullify IMEI (that is, put purely one 0000) - will the operator allow the device to be registered on the network? Or reject?

Answer 1

Will register.
As for the legality of the procedure, there is also no clear violation. In the situation of owning such a phone, the principle of the elusive Joe applies, while you and your friend are not interested in anyone and no one will find out what kind of device it is.
