[Solved] No Network Signal Problem Available on Android | androidbasement - Official Site

The problem "no network signal"Or"not registered on the network"Or"Emergency calls only”Is a problem that can happen to anyone. We have already seen what to do if there is an error no service on iPhone and below we are going to try to understand what to do if we have a similar problem (no signal and / or connectivity) even on an Android phone.

This is perhaps the worst problem that can happen because it prevents you from using the basic function of a mobile phone: make and receive calls. It is true that some areas have connectivity problems, and in this case we can hardly do anything but it is also true that the “no service” problem can also happen where the network is available. In that case it's definitely a phone-related problem and we can't blame it network.

Some of our readers, especially Samsung users, have often complained about these signal problems on their phones. When you try to make a call you discover that there is no signal and an error message such as "Not registered on the network". These problems of network unavailable they can be addressed if they are rare and don't last long, but if this happens very frequently, it can become extremely annoying.

Other types of similar errors you may see are: "No network signal available" or "Error searching the network", "Your SIM does not allow connection to this network" or "Automatically search the network" or "Emergency calls only"

Solve No Network Signal Problem

Before we see how to fix the network problem on your phone, we recommend that you check the SIM works fine on another device. You can use a friend's phone or another family smartphone or tablet. This will help you figure out if the problem is on the network or on the phone. If your SIM is working properly and you are able to make and receive calls smoothly from another device, the problem lies with the device you are using. Otherwise the problem is related to the SIM and in this case it is advisable to contact the telephone operator (Wind, Tre, Vodaone, Tim, etc.)

This is a crucial step to help you figure out if the problem is with the phone or not. Once you have identified the phone as the cause of the problem, you need to figure out if it is a phone software or hardware problem. However, here are the possible solutions to fix this problem.

Solution 1: Restart your Android phone

The fastest solution to this problem is restart the device. Once the device restarts, the system will search for the network again. This is usually helpful, although the problem can only be fixed temporarily and can recur at a later time. For those who experience this problem only sporadically, a reboot can be a quick and easy solution.

Solution 2: Turn airplane mode on / off

Many users have found this solution useful for quickly solving the problem "No signal available". To turn on airplane mode, pull down the notification panel on your phone and look for the airplane mode icon. Touch the icon to activate the mode. Wait 30 seconds and tap the icon again to deactivate the mode.

Once the phone exits airplane mode, it will try to search for networks again.

Solution 3: Check SIM card

Sometimes, if the SIM card is not inserted correctly, you may encounter the problem of theno signal or an error that appears on the screen. To solve this problem you need to turn off the phone and remove the SIM card. Then you have to reinsert the card and make sure it is inserted correctly. If you feel that the SIM card is moving inside the metal bracket then there is a possibility that the movement will cause the connection to be lost and you will get a problem with no signal.

If you notice the SIM moving, take the phone to the manufacturer to see if something can be done (if the phone is under warranty) or have a replacement done. You can also try using a piece of paper on top of the SIM to hold it securely in place.

Solution 4: Choose Network Automatically

All Android devices have the automatic network search function. The mobile network will be chosen automatically by the device and should help you solve the problem. To choose the mobile network automatically, here's what to do:

1. Go to the menu Settings of your mobile
2. Search Other networks and touch it
3. Now touch Mobile networks on the next screen
4. Toccata Network operators and choose Automatically select from the next screen

The device will automatically start searching for networks and will try to connect to the network after identifying one. This should help you solve the problem.

Sometimes, the phone may not receive any signal or service when the radio signal is not broadcast as expected. To fix this, try the following steps:

1. Open the phone dialer and type * # * # * # * # 4636. Dial this number and wait for the results.
2. A test menu will appear on the device screen. Click on the phone / device information from this menu.
3. Run the ping test and then select GSM Auto (PRL) from the drop down menu.

Once this step is complete, restart your phone and see if you can now connect to the network and use the phone to make calls and send messages.

Solution 6: Update phone software

The software of your phone or tablet needs to be updated on a regular basis to avoid problems. When the device is updated, the new software will go on to make various fixes for known bugs or problems in the current software. To update the software on your device here's what to do:

Solution 7: IEMI canceled

There are situations where the number IMEI of the device may have been canceled or there may be a problem with IMEI unknown which can lead to the problem of no signal on the phone. You have to check if your IMEI number has been canceled or damaged by any chance. And if the problem lies in the IMEI number, then it is imperative to reset the IMEI.

1. Log into your phone's dialer and enter the code * # # 06 which will display the IMEI number of your device. If the result is displayed as zero, the IMEI number of the device has been corrupted and you need to take the necessary measures to solve this problem.
2. To solve the problem, dial * # * # * # * # 197328640 from the device dialer. Alternatively, you can also dial * # # 197328640. By dialing this number, you will enter command mode on your phone.
3. Make sure you select Common on your device.
4. Choose the first option that needs to be Field Test Mode (FTM). If you find FTM active, turn it off. Once FTM is disabled, press the Menu button and the IMEI number should be reset.
5. To disable FTM, you must press option 2 using key entry.
6. Remove the device's battery (if you have a removable battery) and remove the device's SIM card as well.
7. Wait two minutes and put the battery back in, but don't insert the SIM yet.
8. Turn on the device and enter the number again from the dialer * # # 197328640
9. Access the screen menu Debug and tap Phone control.
10. Next, you need to click Nas Control and then RRC. The last step is to tap the RRC review and tap Released.

After completing these steps, turn off your phone and put the SIM card back. Turn on the phone and check if the problem is solved.

Solution 8: Factory reset

If none of the previous solutions worked, then all that remains is reset the phone to factory settings. When you reset a device to factory settings, it returns the software to the same state it was in when the phone was purchased. This step deletes all data from the phone and also deletes any apps that may have been downloaded to the phone. So it is necessary backup your mobile before resetting.
