The article provides a comprehensive guide on resolving the mobile network disconnection problem that many Android users face. It outlines 11 simple steps, such as restarting the device, debugging with another SIM card, adjusting network settings, resetting APN, upgrading the SIM, re-inserting the SIM, checking network quality, using a signal booster, and ensuring default settings are not altered, to help users troubleshoot and fix the issue effectively.

Mobile Network State Disconnection is one common issue most Android users face when their phone is not registered to the network. In this article, we will look into the issue of mobile network states being disconnected from Android phones.

What is Mobile Network State Disconnected Error?

We can say that the ‘mobile network state disconnected’ issue occurs once the SIM card fails to register with 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 Fix the Mobile Network State Disconnected Error?

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 Error.

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. We are only doing this as a primary step regarding the network state issue.

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 fixing the other. 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.

Regarding the mobile network state, both the handset and network support 4G; hence, the smartphone will look for 4G, which 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. 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 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 SIMs 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.

5. Reset the Network

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 be resolved once you finish the reset network process. If, in any case, the problems with the network are not resolved, you can try the below troubleshooting steps.

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

The steps mentioned above are for some quick fixes, but it is always recommended that you update your SIM card. So, if you are still using a 3G SIM card, please upgrade it to 4G. However, 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 implementation 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 are still facing the mobile state network disconnecting 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. Check the Mobile Network Quality By an Expert

Even after the network reset and all the troubleshooting steps, the mobile network state disconnected issue persists on your mobile; you need to check the signal reception on your mobile. If you are sure the mobile coverage is available in your area, then you can take the mobile to an expert. Sometimes, the signal reception issue happens due to software glitches or hardware issues like the network antenna complaint. A technician can identify those issues, which can be fixed if possible.

9. Use a Network Signal Booster

In some cases, if you are experiencing a weak network signal in your area, it can cause the mobile network to state disconnected issues. 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 a Signal Booster is a good choice if you get a poor signal inside the building, such as at home or the office. Most signal boosters available in the market are compatible with almost all regional mobile carriers.

10. Uninstall Security Apps From Mobile

Some Android users install security software such as Mobile Antivirus and 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 might get disconnected from a mobile network. If you are using any applications like that, uninstall them. On the other hand, Android devices don’t need antivirus software. Android is a Linux-based operating system that doesn’t need any antivirus software for security.

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

You can alter the network settings and reception methods if the Android device is rooted. 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, if any, in the case of a rooted Android device.

What Does Mobile Network State Disconnected Mean?

Mobile network state disconnected issue (cellular network state disconnected) – Let’s see if you have questions about the mobile network state and the issue. As said above, an issue occurs when the SIM card registration to the network fails. Let us explain the scenario with an example to make it more precise.

Let us think you are using a 3G SIM card on a 4G/5G enabled handset/smartphone, and your carrier supports all the networks, such as 3G, 4G, and 5G, in your area. So, in this case, since your carrier and mobile device support 4G and 5G in the regions, the SIM network (within the SIM Card, 3G SIM in your case) on your device will connect to the 4G or 5G network.

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 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 / 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.

What are the different mobile network states, and why are they important?

Mobile network states tell you how your phone is connected to the mobile network. The main states are connected, disconnected, and roaming. When your phone is connected, it can make calls, send texts, and use mobile data. If it’s disconnected, there might be a problem with your phone or the network. Roaming means you’re using another carrier’s network, which can happen when you travel.

When should I reach out to my mobile carrier for assistance?

If you’ve tried all the troubleshooting steps and your mobile network is still disconnected, it’s a good idea to contact your mobile carrier. They can help you figure out if there are any problems with your account, the network, or your device. They might also be able to give you more specific advice based on your situation.

Can turning off Wi-Fi or using Airplane Mode help with mobile network issues?

Yes, sometimes turning off Wi-Fi can help your phone connect to the mobile network better. If your phone is trying to connect to a weak Wi-Fi signal, it might not switch to the mobile network when it needs to. Airplane Mode can also be useful for troubleshooting. When you turn on Airplane Mode and then turn it off again, it can reset your phone’s connection to the mobile network.

What are APN settings, and how can they affect my mobile network connection?

APN stands for Access Point Name. It’s like a gateway between your phone and your carrier’s mobile network. If your APN settings are incorrect or outdated, you might have trouble connecting to the network. Resetting your APN settings to the default values provided by your carrier can sometimes help fix connection problems.


The mobile state disconnected issue may not happen for any specific handset or with any operator. Whatever your mobile operator is, whether Sprint Mobile, AT&T, T-Mobile, etc., or a handset like Samsung Galaxy, Motorola, Nokia, or Xiaomi, the issue can happen randomly for multiple reasons. As mentoned before, if you have tried the above steps and the problem still exists, we recommend contacting your mobile service provider.
