Mobile Network State Disconnected Issue on Android [Fix & Solution]

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

To clarify, 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. If you are an iPhone user, you won’t find such an issue while using the mobile network.

What is Mobile Network State Disconnected Issue?

If you have a question about the mobile network state and the issue, let’s see. As said above, it is an issue that 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 that 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. So, in this case, what happens is, Since your carrier and mobile device support 4G and 5G in the regions, the SIM network (within SIM Card, 3G SIM in your case) on your device will connect to the 4G or 5G network 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.

Why does Mobile Network State Disconnected Issue occur on Android?

We mostly saw that the Mobile Network State issue 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, it might now work in some cases 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?

The Mobile Network State issue happens mainly on Android devices, and if you are an iPhone user, you may not find any such problem. So, on your Android device, we can have a few
ways to fix the issue. Following are the different ways you can 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 issues. Regarding the network state issue, we are just doing this as a primary step only.

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 is working fine and proceed with other fixed. Ensure to replace the SIM card and use the SIM to resolve the issue before proceeding further.

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 handset and network support 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.

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 Issue. To reset the APN settings, Goto Settings, then select Network & Internet. Then tap on 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 on the many icons (3 dots at the top right corner). Finally, click on the Reset to default option.

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

Reset the Network

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

In most cases, the mobile state disconnected issue might get resolved once you are done with 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.

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. 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 choice in 2022 if you can find one. So that you can avoid the further SIM upgrade in the next 1 to 2 years.

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 state disconnected issue. In that case, you can use any external network signal booster device. For example, you can install the device outside the building where a decent network signal is available. The network booster will boost the signal to better signal quality on your Android and iOS devices.

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

Uninstall Security Apps From Mobile

Some Android users install security software such as Mobile Antivirus and some Malware scanning apps on the phone. Some of these applications can cause issues with mobile networks. For example, some applications might block network settings and low signal reception. 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, and it doesn’t need any antivirus software as a part of its security.

Conclusion

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 due to multiple reasons. If you have tried the above steps and the problem still exists, we recommend contacting your mobile service provider. Before contacting the service provider, make sure your handset is working fine. You can insert some other network SIM on your mobile to check whether it is working.

  1. Could this be the cause of SMS (text and/or pics) to fail sporadically for a given period of time (usually short) & not necessarily from message to message? Also, can it effect connectivity of my “Your Phone” App & “Link to Windows” App between my Android (Samsung Galaxy 9+) & Windows 10 laptop, although I believe they rely strictly on Bluetooth. ( BT itself has become a whole other issue with Win10)
    All from same location & modem/router proximity is not an issue.

    Thanks
