Hi, So the other day my iphone 6s has been displaying “No service”, and therefore I can not make phone calls, text messages, and access the internet. I have tried all the known basic fixes, such as,

  • Time and date issues.
  • Switching the phone on and off.
  • Removing the sim card.
  • Putting the phone in and out of airplane.
  • restoring the phone.
  • I have even taken the the phone to an apple store, for a software restore.
  • Network coverage, and the network coverage is fine. Another thing that I tried was to swap sim cards over with my girlfriend. Her sim card did not work on my phone, but my sim card worked on her phone. Therefore I have concluded that this must be a hardware issue. When I dial *#06# I get my IMEI no. displayed on screen, and it also shows up in the settings. Any ideas as to what the problem might be or where the problems might lie, and can it be fixed? Cheers, Matt

Your troubleshooting has been very good and you have eliminated quite a few things. Has your phone been dropped, repaired or even opened out of curiosity just shortly before you had problems? Did it come in contact with water or high humidity? My thinking is that one of the internal antenna connections may have come loose. The fact that your phone sees the IMEI generally rules out a baseband IC issue. If you’re comfortable, you could open up your device and look for anything out of place such as disconnected connectors, red water indicators etc. However, tread carefully, disconnect the battery first (especially on the 6S) and don’t force anything.

Try this: Hold down the power and home buttons to turn of the phone, and keep them depressed until the phone restarts itself. Continue holding these buttons down until the phone then turns itself back off. Wait a few seconds, then depress them again until it starts up, then let go of the buttons. I’ve heard this has worked for some people. I have also read about the “drop technique” where people put the phone in a case then drop it from about 6 or more inches onto a hard surface with the screen facing towards the ceiling. I wouldn’t personally do this until I’ve tried everything else but many people have backed this technique.

I fixed and solved 90% some of those iphones (around 100 iphone I worked)by replacing cellular cable which is located inside logic board.

Hi my new iPhone keep saying no service then it works but it says no service again it usually works when I use it and says no service when I put it down I have tried all the methods from power on to power off to factory reset but still the same how do I fix this
