The “cellular network not available for voice calls” error is a common issue that can prevent users from making or receiving phone calls on their mobile devices. This frustrating error has several potential causes and solutions that users can try to resolve the problem. 


What Causes This Error Message?

There are a few key reasons why you may see the “cellular network not available” error when trying to make calls on your smartphone:

Network Outage or Poor Coverage

The most straightforward reason is that there is a temporary outage or poor coverage from your cell provider in your current location. If you move to a new area and can’t connect to the cellular network to make calls, it’s likely a coverage issue. You’ll have to wait until you get better signal reception.

Software Bugs

Bugs or glitches in the operating system software can sometimes disrupt access to the cellular network. Rebooting the phone or installing software updates may resolve this.

SIM Card Issues

Problems with the SIM card like damage or connection issues can prevent registering with the cellular network properly. Reseating the SIM card often fixes this.

Incorrect Network Settings

If the cellular data settings like the APN (Access Point Name) are configured incorrectly, it could block voice calls over the network. Resetting network settings to default can help.

Account and Billing Issues

If your cell plan expired or payment failed, the carrier may block access to voice calls while still allowing data. Updating billing info and your account can restore calling ability.

Solutions to “Cellular Network Not Available” Error

If you encounter the “cellular network not available” error on your iPhone or Android phone, there are a number of troubleshooting steps to resolve it:

2. Check for Network Outages

Make sure there are no widespread outages for your carrier in your area. You can contact your cell provider or check their service status online to confirm.

3. Try Airplane Mode On and Off

Toggle airplane mode on, wait 15-30 seconds, then turn it off. This forces the device to re-establish the cellular network connection.

4. Remove and Reinsert the SIM

Eject the SIM card, check it for any damage, then reinsert it carefully and firmly to make sure it’s making full contact.

5. Reset Network Settings

Go into settings and choose the option to reset all network settings back to default. This fixes incorrect network configuration.

6. Update Software and Carrier Settings

Install any pending OS and software updates. Also update your carrier settings by texting a special number provided by your cell provider.
