My iPhone 6 keeps saying no service and my brother who is on the same contract and has an iPhone 6 plus gets perfect connection in the same house!!!! Please help do I need a new SIM card? Or a new phone?
Ok I factory reset and it fixed all the problems!!
Have you tried resetting, resetting network settings, restoring (last resort)? Have you tried swapping SIM cards with the iPhone 6+ just to see if it works? If putting their sim in works with your phone then you immediately know it's a sim problem. If not, then you'll need to try some troubleshooting steps (or contact Verizon to have them troubleshoot with you). You could also try contacting Apple for support (recommended).
Well I reset my network settings now it says Searching... And my brother left so I can't use his SIM card!!!! And I don't want to factory reset my phone!!!
Honestly you may have to. Even after troubleshooting with Apple or Verizon you may be told to do so after trying other things. You can wait until your brother comes back or you can contact Apple or Verizon for further assistance to see what they can come up with.
As long as you've backed up to iTunes or iCloud then performing a factory reset shouldn't cause to much heartache.
