My iPhone voice mail stopped allowing callers to leave a message.
I have an iPhone 7 with Apple Care. About 3 weeks ago callers to my phone number: heard a message that my voice mail was not set up. They were told to try a second time. Same
message. The third time the phone hung up on them. I've tested this several time myself using both my iPhone 5SE and home phone. It continues to do the same thing.
CREDO (my carrier for this iPhone) spent almost 2 hours on the phone with me last Friday. Three different agents worked with me to try to solve the problem. Nothing worked. They gave up and told me I needed to take the phone to Apple. Do you have any advice that I can try before that or do I have to take it in?
