“Cellular Network not Available for Voice Calls” error

This error can be a result of either the software or the hardware issue. Sometimes the root of this is so minor that you might feel embarrassed after knowing it. However, the ways to fix this can slightly differ for Androids, iOS, and also from brand to brand. Regardless, once you get to know the root cause, you can surely figure it out after reading our article. 

The types of Mobile Networks

Before everything, we need to have a slight overview of the different types of mobile networks. This is the only thing responsible for each and every interaction you do on your phone. Without a network, a phone is nothing more than a toy, isn’t it?

But haven’t you noticed sometimes a difference in the nature of the network? To be specific, there are different types of networking technologies. Not all service providers implement the same kind of network technology. One might not be compatible with the other. People subscribe to any of them as suitable and enjoy the benefits that each service provider provides.

The most common four kinds of the network are:-


It stands for “Global System for Mobile network”. Most service providers all over the world implement GSM. It is more frequently found on “T-mobiles” and “AT & Ts”. Faster data over 2G networks are provided by GSM using GPRS and EDGE technologies. It is termed as HSDPA or the High-Speed Downlink Packet Access


This stands for “Code Division Multiple Access”. CDMA has a greater rate of transmission of data. Service Providers like Sprint Nextel and Verizon mostly work using CDMA. EV-DO or Evolution-Data is the technology used to operate 3G CDMA. 


It stands for “Long Term Evolution” and is the latest cellular tech. It has more speed and data transmission capacity over 3Gs and is commonly referred to as the 4G network. 


Communication technology for wirelessly delivering high-speed cellular service to rough geographical areas is under WiMAX’s expertise. Based on the IEEE 802.16 set of standards, it provides physical layer and media access control options. It can be considered an equivalent of a 4G network.

So, these are all four types of cellular networks. Before moving on to the solutions for the “Cellular Network not Available for Voice Calls” error, a grasp of these are necessary. This is because one device compatible with a certain network configuration may not run on the other.

How to fix “Cellular Network not Available for Voice Calls” by using General methods

There are many solutions in general to resolve this issue. Let’s go over them one by one. Check your network type and work on it accordingly.

Toggle between the Airplane Mode being On and Off- 

Switching on “Airplane Mode” and then again turning it off refreshes the cellular network of your device. Just execute the following:-

  1. Find the “Settings” option on your phone.
  2. Navigate to the “Network & Internet” bar. In a different model, it can also appear as “Connection & Sharing”.
  3. Now select “Airplane Mode”. Toggle the bar sideways to activate “Airplane Mode”. You will see the network has been cut off from your device and an “Airplane” symbol appears. 
  4. Then again toggle the bar to deactivate the “Airplane Mode”. 

You should have your cellular network back to normal again in this way. Either way, you can also swipe down the notification bar from above and toggle between the “Airplane mode/Flight Mode”.  

Reboot your Device- 

Toggling “Airplane Mode” may or may not fix the issue. This is because background applications might have hindered the cellular network from making calls or texts. Better try rebooting your device. Android users can just press and hold the “Power” button for a few seconds. Once the “Restart” option appears, tap it to perform a reboot. 

If you are an iPhone user, you should find the lock button on the right-hand side of your device. Long press it and when the “power slider” appears, pull it rightways. This will give your iPhone a reboot. 

After completion of this rebooting process, check if the error is fixed. Wait a minute or two, and then try making a call. If the problem persists, we have other solutions for it as well. 

Remove the SIM card and place it back-

 To be specific, the underlying concept of the phone’s cellular network and a wireless network is not the same. Cellular networks are experts in sending signals over land wirelessly by having certain cell sites as transceivers. These sites carry out everything over the cellular network. Your SIM card plays an important role in receiving and delivering carrier signals over networks. With no SIM card, you can’t get access to a network or communicate. 

Check if the SIM card is placed appropriately. Just pull out the SIM tray using a pin. Pull out the SIM card, rub it with your cloth, and place it back. Proper insertion also needs care. Improper placement can hold back the SIM from working neatly. 

Check if the SIM card is in good condition- 

Always check if your device has suffered any form of damage or not. A SIM being worn out at the edges can also prove faulty. You will never be able to operate on it in that condition. Just open the SIM tray and closely monitor it. If the chip is damaged, rush to your nearest network retailer. They will replace your SIM with a new one. Then place it back in your phone’s SIM slot and check if it works correctly. You should no longer encounter the “Cellular Network not Available for Voice Calls” error.

Update the Firmware-

Always keep your device software updated to the latest version. In older software versions, certain bugs can be present. This can also cause you to get the “cellular network not available for voice calls” error message. Connect your device to Wi-fi if your regular data pack is limited. Now for Android users, the steps to update are:-

  1. Open the “Settings”.
  2. Scroll down to the “About Device” option.
  3. Tap on “Download Updates Manually”. Check if there is any possible update pending.
  4. Update your device.

iPhone users can update their software by:-

  1. Open the “Settings”.
  2. Tap on “General”.
  3. Find the “Software Update” option.
  4. Select “Download and Install” to update your device to the latest update. 

Data Roaming should be turned off-

This particular network mode helps when you are outside your local service provider’s network coverage. This allows you to work on the network of the place you are in that instance. However, the service provider charges a higher bill for using a roaming connection. Although, sometimes people report that even if they haven’t moved out of their locality, the roaming mode gets enabled. And this is why you should disable it. To do this, run over the following steps:-

  1. Open the “Settings” on your phone.
  2. Go to “Network & Internet” / “Network & Connections” (according to your device)
  3. Navigate to the “Mobile Networks”.
  4. When you see the “Roaming slider”, slide it to switch it OFF.

The cellular settings will restore to normal and should work perfectly as they did before. 

Change your position-

In a place where the signal reception is poor, you will definitely face a “Cellular Network not Available for Voice Calls” error. Remote and abandoned places may not come under your service provider’s network coverage. 

Better try moving to a different spot where there is a better signal reception rate. This change of position will surely help you get rid of this issue. You can also change your SIM to another service provider. It might be possible that a certain SIM isn’t compatible with a particular place. If you have a “Dual sim” facility on your device, just switch your SIM to another to check if it helps. 

Check if your cellular network is in Maintenance mode-

Sometimes network carriers undergo a temporary shutdown for performing maintenance. This is very rare and few people encounter it. At that moment, you will be unable to make any calls or texts.  

There is no general solution to bring your network out of “Maintenance mode”. Don’t panic since this issue is short-lived. You can just check if the carrier is in Maintenance mode by looking at their Twitter account. The company will surely put an update if they have rendered their service into maintenance.

So, these were some of the basic and general ways to fix the “Cellular Network not Available for Voice Calls” error. As discussed previously, there are also some Advanced methods to resolve this. If the general solutions won’t work, you can simply try out the advanced methods. So, let’s talk with them.
