Hello! My iPhone 4 keeps saying there is no service even after trying every single possible way to fix this issue. I tried turning on and off airplane mode. Resetting network settings and when it didnt work I restored phone to factory settings. (deleted everything). Tried switching sim cards and also switching on/off other cellular settings. The phone seems to know that sim card is inside as when I take it out it says No SIM and when I put it in I see No Service or Searching. Please help me I am really desperate to get this phone to work.
Maybe you can upgrade your iPhone system
check date & time dial emergency in your country if u get response then check antenna
