How Do I Fix the Mobile Network State Disconnected Error?

Just follow these fixes to resolve the sim card status mobile network state disconnected issue. 

Insert SIM Card Properly

As we have mentioned before, SIM cards are one of the core reasons behind this issue. So make sure your SIM card is properly inserted and functional. If the SIM card is not properly inserted, your device will not be able to read it.

Replacing Your SIM 

If the SIM is properly inserted, you have to understand whether the problem is with your SIM or device. Remove your old SIM card and replace it with a new one; if the mobile network state is connected, the problem is with the SIM card. 

Replace your SIM card permanently to avoid this issue from occurring again. 

Replacing SIM card

Network Reset 

Next, if your SIM card is 3G, you must change the network state priority of your device from 4G/5G to 3G. If your device finds a 4G network, it will try to connect to it repeatedly, which will be rejected by the SIM card. This will result in a technical conflict, and thus, the problem occurs.

Changing the network setting priority from 4G/5G to 3G will direct your device to only connect to a 3G network. 

Check APN Settings

If your APN (Access Point Name) is misconfigured, it won’t be able to connect to any network. You have to reset the APN settings to resolve this issue.

Follow the steps to reset your APN settings. 

  1. Go to Settings and select Mobile Networks. 
    Resetting APN
  1. If you have multiple SIM cards, then select the target SIM and click on Access Point Name (APN)
    Click on Access Point Name
  1. The last step is to click on Reset to Default, and you are done with the process.

Check The Airplane Mode Status

This fix is much simpler than the other and only takes a few seconds of your time. Just go to settings and locate airplane mode to ensure it is turned off.
