Why does the mobile phone display an empty number?

1, maybe the other party blacklisted your number. I suggest you try to contact the other party in other ways, and you can dial normally after removing the blacklist.

2. It may be due to the following reasons: the mobile phone number has been cancelled and is in the freezing period, or it is stored incorrectly, and the mobile phone number does not exist and is not enabled. The other party's mobile phone was turned on and set with the call forwarding function, which caused this number to go to an empty number.

3. The SIM card you are using in your mobile phone is worn out, which makes the signal transmission difficult. The cell phone signal in your area is not good, or you call the other party's cell phone in a specific area, and the prompt is that the number is empty. The internal chip of your BBK phone is damaged.

4. The main reason why the mobile phone number becomes empty is the cancellation of the number. The reason why the mobile phone number is cancelled: I don't have to cancel the number voluntarily.

5. If the number of Unicom mobile phone users can be called normally, the empty number will be prompted during the call. You can try the following methods: Cancel the call forwarding setting of the mobile phone, and when the mobile phone is on standby, just enter ##002# and press the call key. Turn off the computer again and search the network. If your problem is still unresolved, it is recommended to contact local customer service for feedback.
