adjust the number of rings?
I'm on the phone with cell phone carrier to adjust the number of rings.....She is unaware of this? I currently have a 6S but on my original iPhone my 5 - in the phone settings there was an option to adjust the number of ring 3: 5: or 10! I want to know just for me - is the carrier disabling the feature? or did it go away? Plus I buy my phone from the Apple store not thru the carrier. Also disabled, is the feature to give back a text message when it rings: Sorry I can't take your call, Can I call you later, etc. My carrier is Verizon. I do not have Caller ID Blocking.....and don't know what else is missing. Any help greatly appreciated.
