Is anyone else not able to send/receive calls after updating iPhone 4s to iOS 9.1?
Hello everyone,
I just updated my iPhone 4s to the latest iOS, iOS 9.1. Since doing so, I have been unable to receive or send any calls. I am told by callers that when they call me, they hear two rings, and then their calls go to voicemail. I do not hear any of these rings and do not get a "missed call" notification, but I can receive the voicemails. Likewise, when I try to make a call, my phone ends the call before it has a chance to ring. I have tried all traditional troubleshooting, such as ensuring that call forwarding, airplane mode, and do not disturb are off, as well as doing a hard reset. I doubt a factory reset will resolve the issue as it occurred exactly after downloading the new iOS. Is anyone else experiencing this? What can I do to rectify this issue?
Thank you!
iPhone 4S, iOS 9.1
