We both have iPhone 4's on Verizon. She got hers as a Christmas present. When I first send her a text it tries to send it as a iMessage, but then sends it as a text message. Or when I call here I get her voicemail. It really frustrates me been happening for about a week... Would call Verizon but where I live we don't have good reception, even though there's a tower a couple miles away...
Hello Dakota5525! I'm sorry to hear about the problems you've encountered contacting your friend. I'm confident that I can help you find a solution.
In regards to iMessage, please have your friend ensure that iMessage is turned on. Otherwise, messages sent between the two of you will be sent via standard text messages.
I'm not sure why your calls are being routed to her voicemail. Are you able to make calls to other contacts? Does the phone ring when you call? Please provide me with a few more details. Have a great day!
