We have entered an era where we can’t survive a day without our smartphones. We use our smartphones for various tasks, such as sending SMS, making/receiving calls, playing games, watching videos, etc.

Upon all features, a smartphone is mainly known for its ability to make/receive calls, send SMS, and use the internet. If these three things create a problem, our lives can become problematic.

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 faced mostly by those who purchase a new SIM card. So, 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 the wrong network connection mode on your phone. For example, if you have a 4G SIM and selected 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, hardware fault, etc. Below, we have shared a few of the best methods to fix the ‘Mobile Network State Disconnected’ error message.

Before you try the troubleshooting, it’s important to ensure that your SIM card is activated. If you’ve just purchased the SIM card, you must wait a few hours until it’s activated.
