Recently, many Android users reportedly got an unusual error message that reads ‘Mobile Network State Disconnected’. When the error appears, the network symbol icon disappears.

So, if you recently got the Mobile Network State Diconnected error message on your smartphone, check out what the error means and how to resolve it.

What is ‘Mobile Network State Disconnected’ Error?

The ‘Mobile Network State Disconnected’ is a network-related error that appears when your SIM card fails to register with the network.

The problem is mostly faced by those who purchase a new SIM card. If the ‘Mobile Network State Disconnected’ error message appears, your SIM card fails to register with the network.

It will also appear if you have set your phone’s network connection mode to the wrong network. For example, if you have a 4G SIM and select 2G/3G in your phone’s network mode, your phone will attempt to connect to the 2G/3G network instead of 4G.

This creates a network conflict because the SIM is supposed to connect with 4G only. This leads to the ‘Mobile Network State Disconnected’ error message.

Yes, there could also be other reasons, like a network problem or hardware fault. Below, we have shared a few of the best methods to fix the ‘Mobile Network State Disconnected’ error message.

If your Android phone receives the error message due to a network error, you can’t do much in that case. However, you can try the following method to check if the error message can be fixed.

1. Make sure your SIM card is activated

Before you try the troubleshooting, you must ensure that your SIM card is activated. If you just purchased the SIM card, you must wait a few hours for it to be activated.

Network operators usually send a confirmation message after a successful activation. You can try checking your SMS inbox to confirm that the SIM has been properly activated.

You can call them and ask for the activation status; they may ask you a few questions for authentication but will give you the proper reason for the ‘Mobile Network State Disconnected’ error message.

2. Restart your Android smartphone

Network congestion is often the main cause of the Mobile Network State Disconnected error message. You can also restart your Android smartphone to refresh the network connection.

After the restart, your phone will try to make a new connection, possibly ruling out all network congestion. So, before following the next methods, restart your phone.

3. Set the correct network type on your phone

Android smartphones allow you to choose network settings between 2G/3G, 2G/3G/4G, or 2G/3G/4G/5 G. So, if you have a 4G SIM card but the network mode is set to 2G/3G, the SIM card will fail to connect to the network and throw errors.

So, you need to make sure that you have set the network state on your phone that your SIM card supports. If it supports 4G, switch to 2G/3G/4G.

You can also force 4G LTE Mode only on Android smartphones. We hensureuide – How to Force 4G LTE Only Mode on Android Devices.
