Why does the mobile phone display an empty number?

It may be due to the following reasons: 1, the mobile phone number has been cancelled and the recovery is in a frozen period, or it is stored incorrectly, and the mobile phone number does not exist and is not enabled. 2. The other party's mobile phone is turned on, and the call forwarding function is set, which causes this number to go to an empty number. 3. The operator's network is abnormal, which leads to the regional and extensive empty number of users' mobile phones.
