Fix “Mobile network state disconnected” problem

Smartphones and the Internet play very crucial roles in our day-to-day life. You can easily view the network state of your device while using it. So, what is a Mobile Network State? A mobile network state helps you to know the current status of your device’s network connection. It helps you to determine whether your device is connected to a cellular network.

Your device can be in any of these states:   

1. Searching
2. Connected
3. Emergency only
4. Denied
5. Disconnected

Sometimes, you might come across the “Mobile Network State Disconnected” problem. It is one of the most common network issues faced by an Android user. This problem can become very frustrating as you are unable to make or receive any phone calls. Also, you cannot even use the internet unless you switch to a Wi-Fi network.

So, why are you facing the “mobile network state disconnected” issue? You may face this issue when your device is out of range. Sometimes, issues within your device or the network can also cause this problem. There are many reasons which can lead your device into a “disconnected” state. 

Reasons for a “disconnected” mobile state

• Your device may be out of range: You are currently using the device in an area that has very weak or no cellular coverage. 
• Network congestion: The network might be facing heavy traffic in your area. This leads to a network jam and causes a temporarily disconnected state. 
• Device settings: Some settings in your device can also cause connection problems to the network. 
• Damaged Hardware or SIM: Your device’s SIM card slot or the SIM itself may be damaged. This can also lead to a disconnected network state. 
• Software issues: There may be some glitch or bug in your device’s software that is causing this problem. 
• Power-saving mode: Switching to a power-saving mode can reduce the connectivity or completely turn it off. 
• Battery level: Sometimes, the low battery level of your device automatically disconnects you from the network by entering a low-power mode. 
• Network maintenance: Your network may be under maintenance. 

Using a 3G SIM card in a 4G or 5G device may also be the reason behind the mobile network state being “disconnected”. This happens when your device is unable to connect to a 4G or 5G network by using a 3G SIM.

Let us first have a look at some simple methods to solve your “mobile network state disconnected” issue. You can try these methods before jumping to any lengthy methods. 

Simple Methods to fix your “disconnected” mobile network state

• Restart your device: Most issues related to network connectivity can be easily solved by simply restarting your device. 
• Check the network coverage: A weak signal can also cause this problem. Hence, make sure you are using the device in an area with good network coverage. 
• Airplane mode: Sometimes, network connectivity issues can be solved by simply using airplane mode. Turn the Airplane mode on and wait for 30 seconds. Turn it off and check your connectivity status. 
• Check your SIM card: Make sure you have inserted the SIM card properly. Also, check if the SIM card slot of your device is working by inserting another SIM. 
• Mobile data: Reset your network connection by turning the mobile data off and on. 

If you are still facing the issue, there may be some network settings on your device or other factors causing it. Let us have a look at other methods that can fix your “mobile network state disconnected” issue.

Remove Unwanted Apps

Any app using a network connection or that changes the device’s network settings can potentially lead the mobile network into a disconnected state. Removing these apps from your device can solve your problem. Let us have a look at some apps that are responsible for such problems:

• VPN (Virtual Private Network) apps: VPN apps can change the device’s network connectivity by redirecting network traffic through a remote server.
• Battery saver apps: Some battery saver apps turn off network connectivity to save battery. This leads to a disconnected mobile network state. 
• Security apps: Like battery saver apps, security apps like firewalls or antivirus can also lead to this problem. 
• Network optimizer apps: Some network optimizer apps modify the device’s network settings without your knowledge and causing the problem. 

Note: It is not necessary that these apps always lead you to such network problems. Many other factors are also responsible. But, if you suspect that any app is causing such network issues, try disabling it or uninstalling it from your device. 

Use a Signal Booster

A weak mobile signal can also cause the “mobile network state disconnected” problem. When you use your device in an area that does not have good network coverage, it becomes difficult for your device to maintain a stable connection.

You can use a signal booster in this case. A signal booster amplifies the mobile signal to establish a strong connection with the network. 

• Install a signal booster at your home: Signal boosters are available in different forms. It ranges from small portable devices to large systems.
• Connect the signal booster by using a power source and an external antenna: The external antenna helps in capturing the mobile signal from the nearby cell tower. It will then be passed to the signal booster. The signal booster will amplify the signal and send the modified signal to your device.
• Use your device in the area covered by the signal booster: Using amplified signals will help your device establish a strong network connection. This will reduce any disconnections due to weak signal strength. 

Note: A signal booster can solve this problem only if it is due to weak signal strength. Also, signal boosters may not be compatible with all devices. Hence, make sure to check the manufacturer or your service provider before installing a signal booster.
