- Secondary antenna (Point 1 or Point 2 or both) might be faulty. Antenna wire might also be faulty. (Antenna wire connects secondary antenna Point 1 and Point 2).
- Antenna Switch or Power Amp IC might be faulty.
- Restart your phone and check.
- Remove, clean and reinsert SIM card and check, as sometimes this also gets the job done right.

- The very first thing that you need to do is to clean primary antenna and primary antenna contacts and check.
- Replace antenna contact pins and check, as sometimes the spring of antenna pins become loose and are not able to connect primary antenna with antenna contacts hence causing network problems in your phone.
- Check Coil as mentioned in figure and replace it if it is found to be faulty. Besides that, if you don’t have a coil along with you at the moment, you can also replace it with a jumper wire, as it acts exactly like coil.
- Check Point – 1 and Point – 2 of secondary antenna, if any of them is found to be faulty re-solder or replace them.
- Replace antenna wire if it is faulty, as sometimes a faulty antenna wire is also the cause of this problem.
- Now gently heat Antenna Switch and check, if it is found to be faulty replace it.
- Now the next thing that you need to do is to check Capacitor – 1 and Capacitor – 2 from the positive terminal of the battery, if they are faulty then replace. In case there is no connection than you need to use introduce a jumper in this system.
- Check all the surrounding components of Power Amp IC and Check. Replace any of the faulty components.
- Finally heat Power Amp IC, replace it if it is found to be faulty.
