I understand that you are experiencing issues with USSD codes not running on your mobile phone. This can be frustrating, but there are several troubleshooting steps you can try to resolve this problem. Here are some possible solutions:
-
Check Network Connection:
- Ensure that your phone has a stable network connection. Weak or limited network coverage can cause issues with USSD codes [3].
-
Restart Your Phone:
- Restarting your phone can help refresh the network connection and clear any temporary glitches that may be causing the issue [3].
-
Enter Safe Mode:
- Entering safe mode can help identify if any third-party apps are interfering with the USSD codes. Safe mode disables all pre-installed applications and services that came with the phone [3].
-
Reset Network Settings:
- Resetting network settings can sometimes resolve issues with USSD codes. To do this, go to the settings menu, select the network option, and click on the reset network settings option [3].
-
Activate SMS Over IMS:
- Activating SMS over IMS (IP Multimedia Subsystem) can help fix issues with USSD codes. To activate SMS over IMS, go to the phone dialer, enter ##4636##, select phone information, and click on the SMS over IMS option [3].
-
Update APN:
- Updating the Access Point Name (APN) settings can also help resolve issues with USSD codes. Go to the settings menu, select the network option, and click on the APN option. Then, select the new APN option and enter the details provided by your network provider [3].
-
Check Radio:
- Checking the radio settings and ensuring that the radio is turned on can also help resolve issues with USSD codes. If the radio is off, turn it on and try dialing the USSD code again [3].
If none of these solutions work, you may need to contact your mobile network operator for further assistance. They can provide specific troubleshooting steps or check if there are any known issues with USSD codes on their network.
