If the signal strength bar on your phone is low, then that might be the reason you’re unable to make phone calls. If your carrier doesn’t have network coverage in your area, then you won’t be able to make phone calls, but if they do, you would want to reboot your phone and see if things change. There is also a slim chance that the reason you’re unable to call is that the carrier is fixing things on the local tower, so giving it an hour or so might be what you need.

Fix 4: Update Your Phone Software

Running an OTA software update on your phone is one of the proven fixes to the “cellular network not available for voice calls” issue. The reason why this works is that phones have bugs that cause issues like making your phone forget its SIM, so the security updates work to fix this.

To do this, connect your phone to Wi-Fi >> go to Settings >> tap on About Phone >> select Software or System Update (depending on the phone) >> you would most likely find an update that you need to install >> install this, and when your phone completes the update and restarts, check if there is a software update remaining >> after all updates have been installed, the phone would work just fine again.

Note: If you check for system or software updates and your phone says there are none, shut your phone OFF, remove the SIM and try without the SIM. Continue rebooting without the SIM with the phone connected to Wi-Fi until you find and install all updates. You can re-insert the SIM when all updates have been installed and the phone rebooted the last time.

Fix 5: Remove and Re-Insert SIM Card

As simple as this seems, it has been the fix for many cellular/mobile network-related issues. Take out the SIM, reinsert it into the phone and see if that fixes things. If it doesn’t, you can try inserting your SIM into another phone and see if it works. Whatever results should tell if it’s actually a SIM issue or a phone issue.
