Hello, Rdmoore3814. Sorry to hear that! We'd like to look into this for you. Can you send us a private message with your phone number, pin code, and complete address?
I am having the same exact issue (for like 5 months now) I have an IPhone SE as well. Do you know the fix? I am trying to figure out if I need to get a new phone or new carrier. Very frustrating. People call me and I have no idea they have called unless they leave a voicemail or text me saying they have called. I also randomly get call failures every now and again when I have full service coverage. I have tried resetting my network setting, resetting service, checking through all my settings. Any advice would be awesome!
