My iPhone 6 recently started having cellular issues, I put my sim in and it says no service, so I repeatedly take it out and put it back, which then displays my network with no signal bars. I try to make a call and it says failed. Any ideas thanks

Have you restarted the phone? If you haven’t, try that. You could also try a hard reset, hold the power and home buttons until the phone shuts off and keep holding until the Apple logo comes back on.
