No service, No ICCID, carrier settings flashing up intermittently
Hi there,
I've been having a problem recently with my phone 6s, one night it stopped having cell service. Many reboots, refreshes and resets later, it came back. Unfortunately it's happened again and my phone is once more useless.
Normally when I open settings, I have airplane mode, wifi, bluetooth, mobile, data and carrier; now, the carrier option is missing, however occasionally flashes up. (iPhone problem - YouTube) When I open settings -> general -> about, there is no ICCID number, this however reappears when I put the phone into airplane mode.
IOS is up to date, tried with both current public release and the beta 11.2.5.
Carrier setting are up to date.
Sim card works no problem in other iPhones, both same model and 5/5s
iPhone 6s, iOS 11.2.2
