Need to make a phone call but your phone isn’t working? Maybe you should obtain a decent-budget phone to make calls without any issues. Here are several quick fixes for the “cellular network not available for voice calls” error notice on your phone.

1. Remove the SIM Card

A mobile network is not the same as a wireless network. On the one hand, a mobile network is a communications network that is spread across an area and is linked wirelessly via transceivers such as cell sites.

Cellular carriers have cell sites located around the country, allowing them to offer mobile carrier signals and mobile networks. Herein lays our first solution: if your phone is connected to a mobile network via a SIM card, it can send and receive texts and calls.

As a result, if you receive the “cellular network not available for voice calls” error notice, one place to start examining is whether you were able to properly insert and put your SIM card into its slot. Modern smartphones have a SIM tray that may be accessed by inserting a pin into a small hole to eject the tray. Before placing the SIM card back into the tray, be sure it is securely in place.

2. Restart SmartPhone

After re-inserting your SIM card, perform a quick restart to ensure that any improper background processes that may be interfering with your ability to make or receive calls and texts have been erased.

Long press the lock button on the right side of the iPhone and push the power slider to the right when it displays.

Long-click the lock button on the right side of your Samsung phone, then tap Restart.

After rebooting your device, check to see whether you are still seeing the “cellular network not available for voice calls” error message. If so, you can proceed with the next steps.

3. Update Smartphone Software

It is well known that bugs may wreak havoc on how your phone performs. Bugs can also be the source of the “cellular network not available for voice calls” error message. Fortunately, when consumers report concerns like this, both iOS and Android developers respond appropriately. As a result, developers release updates as soon as possible to solve this and other serious concerns.

Simply open the Settings app on your iPhone and then hit on General. Then, choose Software Update. Tap on Download and Install if an update is available.

The same technique applies to Samsung/Android smartphones; enter the Settings app. Scroll all the way to the bottom of the window and then click Software Update. Select Download and Install. Any available updates will be scanned by the device.

4. Change the network selection to Automatic

Sometimes, due to bugs or strange occurrences, your phone’s network selection is incorrect. This implies that even if you have an AT&T sim card, your selection is set to Verizon. The best approach to resolve this is to set your network selection to automatic and resume using your carrier’s services.


  1. Launch the Settings app and navigate to Connections.
  2. Select Mobile Networks, then Network Operators.
  3. Make sure the Select Automatically switch (in blue) is turned on.


  1. Launch the Settings app, then select Mobile.
  2. Choose Network Selection.
  3. Make sure the Automatic switch (in green) is turned on. Otherwise, go ahead and tap it.

5. Inspect the SIM Card for Damage

Faulty SIM cards could also be the cause of a cell network not available error message, which prevents you from making or receiving phone calls. Damaged SIM cards are easy to identify; you’ll know your SIM is no longer functional when you check your phone’s status bar and it says No SIM Card despite having one in the tray.

Simply remove the SIM card from your SIM tray and insert a new SIM to pinpoint the problem. When it resolves the issue, it is time to make a changeover to resolve the issue.

6. Inspect for cellular network Maintenance

Carriers occasionally, but not always, execute maintenance that causes their services to be briefly unavailable. This could very well be the reason you were receiving the “cellular network not available for voice calls” error message and were unable to make or receive calls at the time.

Fortunately, you may easily determine whether your carrier is undertaking system maintenance. Simply go to their social media accounts preferably their Twitter or Facebook pages and see if there is an update on their pages. Typically, they do this to make it easier to reach their customers and avoid irate customers.
