Fix problem: How to change cellular network not available for calls?
Android is popular because it is perfect for beginners as well as advanced users. But it is prone to bugs because its Achilles is the network problem.
You might have seen a message like “Non-phone mobile network available” when you are trying to make a call if you come back from a long journey. It happens a lot and lasts for a very short time in most cases. If the problem persists, even so, here’s a list of what this message can do and a list of what can be done.
Causes of these error
In particular, this error message is a common result that there is no mobile network signal. Most phone models show this when it happens. Samsung Galaxy phones, in particular those that use T-Mobile or Verizon, are however notorious for them.
Getting this message may just be a small bug, but it might actually be a sign of a malfunctioning operating system if the problem doesn’t solve itself quickly. In addition to the wrong or no signal, the coverage of your phone, your current location, and a wrong or corrupted SIM card could cause the problem.
How to Fix this issue?
Check Flight Mode
Make sure that it is not only flight mode enabled and prevents phone calls before you take any further taken care. Go to your home screen, and then go down the top of the screen to check this. One of the settings included should be flight mode (or airplane mode).
Choose a Network Operator
Your smartphone will change your network operator when you go abroad. Network operator search is set to automatically on many phones by default, but some advanced users like to disable and manually search. You may have forgotten to select an operator if you belong to the second group, or your phone will not allow you to do so since it cannot update your location. Anyway, you may want your phone to be searched for the network automatically. So on most Android devices, this is how to do this.
- Go to the “Settings” menu.
- Tap “Wireless and networks.”
- Find “Mobile networks.”
- Enter “Network operators.”
- Choose “Select automatically.”
Update Your Device
A system update helps to solve many problems with the operating system. So give the update a shot if you think the OS is to blame. The current location may vary, but the overall process is quite the same.
- Go to your phone’s Settings.
- Find the “About device” or “About phone” option. It is under the “System” tab on many phones.
- Find and tap the “Software update” option. Some devices might have this option directly under the “System” tab.
- Tap “Check for updates.”
- If there is a newer OS version available, install it.
Replace the Battery
Android device batteries can very quickly be damaged due to the heat generation of your phone while being used excessively and for a long time. The battery can also be damaged if your phone is left on the charger longer than necessary. If the battery of your phone can be removed, try this way. If you suspect your battery is damaged, please take your phone to an authorized repair shop.
A power cycle may solve your problem as it resets and restores your network provider connection. If your phone battery is removable, it is a good way to fix failures. To power, your device, remove the SIM and the battery. You have to turn off your device. Just remember that you should do so as carefully as possible.
Check the Verizon APN Settings
Try updating the APN settings if you use Verizon, but nothing works so far for you. So are the values: The values:
- Name: Verizon
- Port: Not set
- APN: internet
- Username: Not set
- MMS proxy: Not set
- Password: Not set
- Proxy: Not set
- Server: Not set
- MCC: 310
- MMS port: 80
- MNC: 012
- MMSC: http://mms.vtext.com/servlets/mms
- APN type: Not set or Internet + MMS
- APN Protocol: Default
- Authentication type: Not set
- Bearer: Not set
Perform a Factory Reset
Another potential solution to OS problems is to reset a factory if your device OS is up-to-date. Make sure you back up important information in advance, as it clears all your phone settings, applications or even personal files sometimes. To reset a plant:
- Go to “Settings.”
- Look for the “Reset and Backup” menu. The name of the menu may vary but the word ‘backup’ should be included.
- Search for a “Factory Data Reset” option. Do it every time you’re ready.
