Just looking to see if anyone else is having this problem. Activated my 6 Plus yesterday with no problems at all. Data is working perfectly so never thought there was an issue. I just went to call my dad and the call doesn't go through. Tried the house phone and it goes right to voicemail. Phone switches from LTE down to 4G but just sits on "calling". No sign of any connection. Turned off iMessage and regular texts don't go through either. Sent one to myself and it didn't come right back. Visual voicemail can't even be selected at all either I put my SIM into my old 5S and same exact thing. So I know it's not the phone at all.
