No Network Signal in Mobile Phone Problem and Solution
Mobile Phone No Network Signal Problem and Call Drop Problem and Solution – No or week network signal or call drops. Learn how to solve and fix this problem
No Network Signal in Mobile Phone, Network Not Available, Week Network Signal or Call Drops are some of the very common problems faced by many Mobile Phone Users of AirTel, Vodafone, Idea, Jio etc. Here we will learn how to solve and fix this problem.
Sometimes we observe that there is no Network in mobile phone or Android Smartphone even after inserting a new SIM card or SIM card is there but there but Network is Not Available or it is too Week. Sometimes it also happens that the signal keep fluctuating.
Here I will explain some possible reasons and their solution.
No Network Signal in Mobile Phone – Problem & Solution
There can be different symptoms, reasons and solutions to identify, solve and fix this problem.
- Check the SIM Card. See if the SIM is OK or not. Insert the SIM Card in other mobile phone and see if the Network Problem and Call Drop Problem is still there or not. I have personally observed that sometimes the SIM card itself gets faulty for some reason and needs to be replaced with a new one. I have myself replaced my Airtel and Vodafone SIM card two times to solve this problem.
- Also try to insert another SIM Card in the Same Mobile Phone which is giving the problem.
- If there is problem with the SIM Card then try to change or replace it.
- If the problem is still not solved then upgrade the Software / Operating System (OS) to the latest version. Also Rewrite the IMEI Number of the Mobile Cell Phone.
- If the problem is not solved then you may have to change the Mobile Phone PCB.
Other Possible Solutions on How to Fix Mobile Network Not Available Error on Android, iPhone or Any Feature Phone
- Check Airplane Mode: Is your phone in Airplane Mode? Go to phone settings or Swipe down the notification panel on your phone and Turn OFF the Airplane Mode. Wait for the network signal to return.
- Remove and Reinsert SIM Card: Make sure that the SIM Card is NOT loose and is properly inserted. Turn off your phone, remove the SIM card, and carefully reinsert it. Make sure it is securely in place and then turn you phone back ON.
- Check Signal Strength: If your phone signal strength indicator showing weak signal? If it is low or fluctuating, move to an open area away from obstacles like trees or buildings. Sometimes, a weak signal is due to environmental factors like cloud, rain or other harsh condition. Move to a cleaner location and check the connectivity.
- Network Settings Reset: Sometimes resetting network settings can resolve issues related to connectivity. Go to >> Phone Settings >> “Network” or “Connections” >> Reset Network Settings. Note that this action will remove saved Wi-Fi passwords, so be prepared to re-enter them.
- Restart Your Phone: Restart your phone. Power it OFF, wait a few seconds, and then turn it back ON. This can resolve most small and temporary glitches and phone issues.
- Update Your Phone Software: Outdated software can also lead to various problems, including network issues. Check for available software updates in your phone’s settings and install them if any update is available. Regular updates often include bug fixes that can improve overall performance of your phone.
- Contact Your Service Provider: If the problem still persists after trying the above steps, the SIM Card might be corrupt or it may be a network-related issue. Contact your mobile service provider and inquire about the issue. They can provide further assistance and troubleshooting steps

Hellow Mr. Santosh,
I have an issue with the Samsung Galaxy Note 8. Firstly 2 days back the network went off but after restarting a couple of times, it came back in like 40 mins. And Yesterday the network again went off. Even after restarting and waiting for hours, it did not solve. Soo i tried a couple of things and then finally Factory Reset the phone. Now when i checked and tried to update, it says Processing Failed. And on the IMEI Slot section in About Phone, it is showing as “Unknown”. When i try to check the IMEI by *#06#, a black screen appears and it hangs. I am not getting any signal. When i try to open the Sim Card Manager, a black screen appears and it hangs. Kindly advise what should be done?? What can the issue be?? Thanks.

I keep using Airtel network. I am not facing issues with android or iphone but only in small phone. What can be a rootcause? Support pls.
This is very strange problem. I don’t think there is any Hardware or Software Issue. I think it has to do something with frequency of the Towers. Try to Use a Small Phone that supports 4G.

Santosh Sir, Thank you for this helpful article. My query is that, I just replaced my broken display of my mi max, before that I used to get 1-3 mbps data speed but after the display repair my network speed is reduced to speed of 2g network, I tried flashing my rom again but the issue persist, so is there any part damaged during the repair? What should I do now? Please help!
I don’t think any part is damaged. If any part related to network was damaged then you would not get even 2G. Just check if the Internal Network Antenna are Inserted properly or Not. Try to Check the Antenna Connector with IPA. Also check the Network Settings.

Sir , recently i got my micromax android a1 AQ4502 flashed to stock ROM , android 5.1..SINCE THEN MY PHONE ISN’T SHOWING ANY NETWORKS AT ALL . However it is reading the sim card..i’ve tried everything possible like checking my tata docomo sim in different phone (it’s working) , putting another working sim in my phone ( no networks again), Factory Reset, upgrading my phone to android 6 , got the phone’s antenna checked but nothing has worked . also Jio4gVoice app which was working prior to flashing is now not been able to configure with jiofi device after that..To sum up I would say i’ve not been able to place/receive calls neither from android calling app nor from jio4gvoice .
Please help me solve the issue.
Thank you
You have to change the NETWORK IC.
After flashing my phone also don’t show the IMEI no. for both the sim slots .
Is flashing done properly?
Yes, that was the issue..flashing wasn’t done properly.. So I got it reflashed..
Good news: I got the IMEI’s back.
Bad news :my phone’s internal memory got reduced to 4gb , which was 8gb initially .
What should be done now?

HeLLO sir
I’m facing network problem in my Lenovo P2, The signal is going blank completely and coming back after 1 to 2 mins and this is happening only on sim slot 1 and sim slot 2 .There is no network in the mobile phone.
There is less or weak network signal.
Sometimes there is signal and sometimes there is no network signal.
There is network signal for some time and then there is no signal at all.
Clean the SIM connectors with IPA or Alcohol or Petrol and let it dry and insert the SIM back and check. If the problem is still there then change the SIM to another Service Provider and check. If the problem it still there then get the software updated.
Most of the time mobile network problems occur due to the technical faults in your mobile network service provider.

I have an Optimus 2 zone that has a broken antenna connection inside the phone itself. There are the two tabs that touch when putting the phone together that are for the antenna. I have found that hooking a wire to a tab and touching a leg on one of the circuits in the bottom left corner when looking at the back of the phone will make the 3g come on. Tried to solder it but it won’t respond now. Didn’t burn anything and the WiFi works perfect. I am using the phone now on WiFi. Do you happen to know where exactly I need to make this link so it will respond on this phone? Thank you.
Have u any teaching batch.
No. I had a Training Center but closed it because of other important projects.
