How To Fix Mobile Network State Disconnected Issue on Android

Mobile Network State Disconnected issue is one common issue most Android users are facing all the time. But at the same time, it doesn’t mean that all the Android users are getting the issue.

To make it clear, we can say that the mobile network state disconnected issue comes once the SIM card fails to register to the mobile network. Once the SIm card registration fails, the user can’t make calls, send SMS, or even use the mobile internet.

What is a Mobile Network State Disconnected Issue?

As said above, it is an issue that occurs when the SIM card registration to the network fails. To make it more precise, let us explain the scenario. If you use a 3G SIM on a 4G enabled handset/smartphone, the carrier supports 3G and 4G in your area.

Since your carrier and mobile device supports 4G, the SIM network on your device will connect to the 4G network because the priority in the network connection is always for 4G by default. Once it tries to connect to the 4G network, there will be a network conflict because the 3G SIM card on your device is trying to connect to an unsupported 4G network.

Why Mobile Network State Disconnected Issue occurs on Android?

Mostly we saw that the issue regarding the Mobile Network State happens on Android devices. On Android, there is a mechanism to automatically identify each network and provide the SIM card with the appropriate signal. However, in some cases, it might now work due to some network conflict, and you may end up with the Mobile Network State Disconnected Issue.

How to Solve the Mobile Network State Disconnected Issue?

Following are the different ways you can try to fix the Network State Disconnected Issue.

Restart your Device

The first and foremost step that you can do in any issue related to the smartphone is to restart the device. Restarting the device will help you stop all the previously opened apps and services that can help you solve most of the issues. Regarding the network state issue, we are just doing this as a primary step only.

Setting the Network State to 3G From 4G

The next step we need to do is to change the network state from 4G priority to 3G priority. Since you are using a 4G enabled handset, the network priority will be as follows

  • 4G/3G/2G
  • 3G/2G
  • 2G only

By default, the device will have the 4G/3G/2G priority in which the mobile will search for 4G first, and if no 4G available, it will search for 3G and then 2G.
Here, in the issue regarding mobile network state, both handset and network supports 4G and hence the smartphone will look for 4G and it is available, but SIM card rejects it and result in the issue.

So change the network selection priority to 3G/2G so that the device will skip the 4G network and only look for 3G and 2G.

So, in most cases, this will solve the issue.

Resetting the Network

If the above step didn’t fix your issue, we could recommend resetting the network settings on your device (No need to factory reset the device).

Once the network is reset, you can use the above method (method 2) to fix the Mobile Network State Disconnected Issue.

Upgrade your SIM Card to 5G or 4G

The steps above mentioned are for some quick fix but always recommended to update your SIM card. If you are still using a 3G SIM card, please upgrade it to 4G at least. But if you can get a 5G SIM card, it will be the best choice since most of the telecom operators in the world are already using 5G technology, and the rest are on the path to implement soon.

So getting a 5G SIM rather than a 4G SIM will be the best choice in 2021 if you can find one. So that you can avoid the further SIM upgrade in the next 1, 2 years.
