How to remove the mobile phone call barring?

Call barring on a mobile phone can be removed by the following methods:

1, mobile phone settings. Enter the "Settings" menu of the mobile phone, find "Wireless and Network" or similar options, select "Call Settings" after entering, and find and cancel the enabled call restriction function in the call settings.

2. Turn off the flight mode. Turn off the "Flight Mode" switch in the phone "Settings".

3. Turn off "Do Not Disturb" mode. Turn off the Do Not Disturb switch in Settings.

4. Check the call forwarding settings. In Settings, check the call forwarding option in Phone Settings to make sure it is not enabled.

5. Unfreeze specific numbers. Check Blocked Contacts or Call Blocking and Identification in Settings to find and unblock specific numbers.

6. Contact the operator. If the above methods can't solve the problem, it may be caused by the operator's settings or network restrictions. At this time, you can contact the operator, provide identification and mobile phone number, and request to cancel the call barring.

7. Dial a specific code. Some operators or mobile phone models allow call barring cancellation by dialing a specific code. The specific code may vary by region and operator, so you can consult your local operator or consult relevant documents to obtain it.

8. Reset the network settings. In some cases, resetting network settings, such as Wi-Fi passwords and VPN settings, may help solve the call barring problem. This will clear all network settings, so please back up important information before operation.
