Mobile Network State Disconnected issue is one common issue most Android users face where your phone is not registered on a network. But at the same time, it doesn’t mean that all Android users are getting the issue. Once the mobile network is disconnected, users think the connection is blocked. In this article, we will look into the issue of Mobile Network State Disconnected on Android Phones.

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.

How to Solve the Mobile Network State Disconnected Issue?

The Mobile Network State issue happens mainly on Android devices; you may not find any such problem if you are an iPhone user. So, we can have a few ways to fix the issue on your Android device. Following are the different ways you can improve the Network State Disconnected Issue.

1. Restart your Device

The first and foremost step you can do in any smartphone issue 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 problems. Regarding the network state issue, we are just doing this as a primary step only.

2. Debug the Mobile using Some Other Network SIM card

Even after restarting the mobile, if you are experiencing the issue, you need to check whether your handset is working properly. To find it, the best way is to insert some other network SIM card (if you have any). If the mobile state is connected, you can confirm that the handset works fine and proceed with the other fixed. Ensure to replace the SIM card and use the SIM to resolve the issue before proceeding further.

3. Setting the Network State to 3G From 4G or 5G

In the next step, we need to change the network state from 5G or 4G priority to 3G priority. Since you are using a 5G/4G enabled handset, the network priority will be as follows

  • 5G/4G/3G/2G
  • 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 is available, it will search for 3G and then 2G.

Here, in the issue regarding mobile network state, both the handset and network support 4G; hence, the smartphone will look for 4G, and it is available, but the SIM card rejects it, resulting in the issue.

So change the network selection priority to 3G/2G so the device will skip the 4G network and only look for 3G and 2G. So, in most cases, this will solve the issue.

4. Reset the APN Settings on Your Android Phone

Resetting the Access Point is also a troubleshooting method to fix most Android Phone’s Mobile State Disconnected Issues. To reset the APN settings, Goto Settings, then select Network & Internet. Then tap the SIM card & mobile network option. Next, you need to click on the SIM card listed. For example, if you use two SIM on your device, you may find two SIM cards. Next, click on the desired SIM card.

Now, you may find an option called Access Point Names (APN); tap on that. Next, click the many icons (3 dots at the top right corner). Finally, click the Reset to default option.

After the above steps, restart the device to check whether the Mobile Network state disconnected problem is resolved.

If the above step didn’t help you fix the issue, we could recommend resetting the network settings on your device. Network resetting is only needed here, and there is no need to do the factory reset. For almost all network-related issues, the ideal solution to fix the problem is to reset the network on your mobile. The good thing about resetting the network alone is that it won’t do the phone’s factory reset. Instead, it will clear all the network settings within the phone.

In most cases, the mobile state disconnected issue might get resolved once you finish the reset network process. If, in any case, the problems with the network are not get resolved, you can try the below troubleshooting steps also.

6. Upgrade your SIM Card to 5G or 4G

The steps mentioned above are for some quick fixes, but always recommended to update your SIM card. So if you are still using a 3G SIM card, please upgrade it to 4G. 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 decision in 2023 if you can find one to avoid further SIM upgrades in upcoming years.

7. Re-insert the SIM

If you still face the mobile state network disconnected issue, try reinserting the SIM card. Switch off the mobile, remove the SIM card from your handset, insert the same SIM card, and turn off the mobile. Now check whether the network state disconnected issue is fixed or not.

8. Use a Network Signal Booster

In that case, you can use any external network signal booster device. For example, you can install the device outside the building with a decent network signal. In addition, the network booster will improve the signal on Android and iOS devices.

Using Signal Booster is a good choice if you get a poor signal inside the building, such as at home, office, etc. Most signal boosters available in the market are compatible with almost all regional mobile carriers.

9. Uninstall Security Apps From Mobile

Some Android users install security software such as Mobile Antivirus and some Malware scanning apps. Some of these applications can cause issues with mobile networks. For example, some applications might block network settings and low signal reception and your phone gets disconnected from mobile network. If you are using any applications like that, uninstall them. On the other side, Android device doesn’t need antivirus software. Android is a Linux-based Operating system that doesn’t need any antivirus software for its security.

10. Make Sure that Any Default Network Settings is Not Altered

If the Android device is rooted, you can alter the network settings and reception methods. So, revert all those changes if your device is rooted and has done any network modification. Getting the proper signal might be an issue if the setting gets changed. So always make sure to revert any modified network option in the case of a rooted android device, if any.

Let us think you are using a 3G SIM card on a 4G/5G enabled handset/smartphone where your carrier supports all the networks, such as 3G, 4G, and 5G, in your area.

This is because the priority in the network connection is always for 4G or 5G by default. However, once it tries to connect to the 4G network or 5G network, there will be a network conflict because the 3G SIM card on your device is trying to connect to an unsupported 4G network / 5G network.

The reality is that even though the handset can connect to 4G and 5G, the SIM card you are using on your device will only connect to the 3G network, not the 4G and 5G. This conflict causes the network issue, and you may experience the Network State Disconnected Issue.
