iPhone 6s sometimes will not ring. My phone is not on silent or in airplane mode. I don't even get a missed call notification, what is happening?
Since the first day I had my phone, it's been very selective about the calls it will ring for. At first I thought it was because the phone was new and that the glitch would work itself out. I've had my phone now since Black Friday of 2015 and the problem persists. My phone sometimes simply will not ring whether it's on loud or silent. I also don't get any notifications of missed calls and only find out when the person trying to call me lets me know by some other means. My husband tried to call me 7 times the other day, and only on the 7th time did my phone actually ring. I didn't even believe him until he sent me a screenshot of his outgoing calls which indicated that he had indeed called me that many times. This is getting really frustrating for me and for the people who try to call me. My phone is not on airplane mode or set to "do not disturb," the software is also completely updated. It simply decides when it wants to ring or not. What can I do? Is this a network issue? My husband has the same network and his phone works perfectly (although I have no knowledge of how networks work haha). Does anyone have a similar problem, or can offer some advice? Thank you.
