Troubleshooting Lost Signal on a Smartphone. After in the previous post Things that Makes Smartphone Signal Lost That You Should Know, we discussed the things that can cause your smartphone to not get a network signal, so this time we will provide information on ways to resolve the issue. When the signal on your cellphone suddenly disappears, you have to find the point of the problem.
To solve the problem of a signal that suddenly disappears the first thing you need to do is to try to check the condition of your SIM card. Try to check the active period of your SIM card first, because sometimes we often forget to pay attention to the validity period of the SIM card because it uses the wireless signal too often. If you have confirmed that your SIM card is still active, then try to move your SIM card temporarily to another cell phone to see if the other cellphone also does not get a signal.
If after you move the SIM card to another cellphone / smartphone you still don’t get a signal then that means your SIM card is in trouble and you should immediately go to the customer service provider office to take care of the SIM card replacement process with the same number. However, if on another cellphone / smartphone you get a signal it means that the problem is on your smartphone and for that let us discuss some ways to solve it:
1. Restart the Smartphone
Restarting a smartphone is the easiest way to solve the problem of not getting a signal. By restarting, all programs will run from the beginning again so that if there is a program error when running it will be resolved by restarting. This method only applies if indeed the cause of the lost signal is due to a crash on the system running on your smartphone.
2. Airplane Mode Method
The way to solve the problem of missing signal that goes forward is to activate the airplane mode on your smartphone for a few moments and then deactivate the airplane mode. By doing this, the smartphone will scan the network around you that is compatible with your operator’s SIM card provider.
3. Perform a Manual Network Search
Not infrequently smartphones that experience problems do not appear due to the inability of the device to lock the signal from the operator automatically. If this happens then of course your smartphone device will not be able to receive signals, and to overcome this you can try to do a signal search manually and then lock the signal operator that matches your provider that has been found from the search results.
4. Bad Radio Signal
The lost signal can be caused by our cellphone not emitting the correct radio signal. Therefore, to overcome this you must enter the code *#*#4636*#*# in the dial pad of your cellphone. Then a menu display will appear, and select Phone Information. After that click Run Ping Test then scroll down and select LTE / GSM auto (PRL). Then tap on the Turn Off Radio button. When all processes are complete, restart your cellphone and see the changes.
5. Check SIM Card Installation
Cases of signals that are lost or appear but then disappear and reappear are also sometimes caused by the SIM card installation not quite right on your smartphone. Therefore it does not hurt if you check and fix the SIM card installation position on your smartphone.
Even so, such cases can also be caused by problems from the signal equipment of the provider, so it never hurts you to contact the customer service to interpret it.
6. Replace the Damaged Hardware
If the previous methods cannot solve the problem of your lost smartphone signal, it can be ensured that there is hardware on your smartphone that is having problems or is working. If this happens then you have to replace the problematic hardware component. We recommend making a replacement by someone who is experienced in repairing smartphone devices. If it feels quite troublesome or feels expensive then you better replace your smartphone with a new one.
Well hopefully some of the ways above can solve the problem of the signal on your lost smartphone, so you can smoothly communicate with your family or office at work. Thank you and also don’t forget to read Secret Codes for Samsung Smartphones that are very useful
