How Do You Fix “Cellular Network Not Available For Voice Calls” Error Message?

There are many fixes to try:

Solution 1: Improve Your Signal Strength

You won’t be able to make phone calls, send texts, or access data roaming if you’re in an area with bad coverage. This is the first thing you should rule out whenever the “cellular network not available for voice calls” error appears. Simply check the top of your phone screen. You should have 3 or more bars if you have decent signal strength. Or, walk around until you are in a spot with good network coverage. Related Reading

Solution 2: Set Phone’s Network Selection to Automatic

Your phone searches for network operators automatically. However, you can disable this, which most advanced users do. You’ll need to manually select your network operator. Or else, the error will appear. To make things easy, change the network search back to automatic. On Android phones:
  • Go to Settings > Tap Connections > Find Mobile Networks
  • Go to Network Operator, then choose Select Automatically
On iPhones:
  • Go to Settings > tap Mobile Data
  • Click on Mobile Network
  • Toggle the Automatic option on (should turn grey to green)

Solution 3: Disable Flight Mode

The issue can also appear if Airplane Mode is switched on. When it’s running, it will prevent you from connecting to cellular towers, which means you can’t make phone calls or even access the internet. To fix this on Android devices:
  • Open Settings > Network & Internet
  • Toggle Airplane Mode off
On iPhones:
  • Go to Settings
  • Toggle the switch next to Airplane Mode off

Solution 4: Reboot Your Phone

Software glitches can cause various issues, including the voice calls error. If it’s a minor glitch, you should be able to switch your phone off and back on to take care of it. Otherwise, you will have to do a force restart. This is essentially a regular reboot but more comprehensive. The process you need to follow on Androids differs depending on your model, but you can press and hold the Power and Volume Down button for around 10 seconds to get the job done. On iPhones, it gets a bit more complicated. Follow this guide by Apple.

Solution 5: Software Update

The error message can appear when your operating system is bugging out. If you don’t regularly update your OS, this could be the issue. If it’s an outdated OS that you’re facing, you will face various problems and not just the cellular network error. To update an Android:
  • Open Settings > About Device > System tab
  • Tap System Update and click Check for Updates
To update an iPhone:
  • Open the Settings app
  • Go to General > Select Software Update
  • Tap Install Now

Solution 6: Reset Network Settings

Faulty network settings can also cause your cellular network to act up. You may have downloaded an OS update that accidentally changed these settings. To fix this and get phone calls to work again, you need to reset your network’s settings. It’s easy to do, but keep in mind that your saved Bluetooth pairings and WiFi passwords will be lost in the process. On Androids:
  • Go to Settings > Tap System
  • Select Reset Options
  • Click on Reset WiFi, Mobile, and Bluetooth > Reset Settings to confirm
On iPhones:
  • Open the iPhone Settings menu
  • Go to General > Transfer or Reset iPhone
  • Reset > Reset Network
  • Enter your device passcode to confirm

Solution 7: Factory Reset Mobile Phone

You might be dealing with a complex software problem that only factory resetting can clear. To make sure your personal files and data are not lost, back up your files before proceeding. To factory data reset an Android:
  • Open Settings > General & Backup and Reset
  • Tap Factory Reset > Reset Device > Delete All
On iPhones:
  • Open the Settings app > General > Transfer or Reset iPhone
  • Tap on Erase All Content & Settings
  • Enter your Apple ID password when asked

Solution 8: Change Your SIM Card

Your SIM card needs to be in good condition to connect to your network operator. If it doesn’t work properly, you may have damaged it. Eject your SIM tray and examine it for any damages. You can contact your carrier and ask them to change your SIM.

Solution 9: Contact Manufacturer

Hardware issues can also lead to the voice calls error message. The antenna switch could be damaged. Contact the store you bought it from to get it fixed. Depending on your device warranty, you can get the damages fixed for free.

Solution 10: Contact Your Cellular Carrier

If all else fails, there’s a chance that your carrier is facing an outage. You’ll have to wait for the carrier to sort it out. If this is the cause of the voice calls error, you will see other users complain about this error message online. Your carrier will probably put out a notice on their server status page, or social media accounts.
