Question: Input Billing Info in Itunes
My wife has her own Apple ID and a Apple 5C iPhone. She wants to get on Messenger, so I went to the App store, found the app and was instructed to sign in iTunes with credit card info. This I did I filled out all the info until a phone number was requested. In the phone number box there were some grey numbers. I was not able to put in my phone number. After trying for an hour or so I gave up. What can I do?
