Unsuccessful Activation
I bought a IPhone 13 yesterday. everything was going well until I got the error Unsuccessful Activation for my IMessage, and FaceTime. I tried all the troubleshooting options on the Apple Support page. Including resetting network settings. Nothing was working so went into my new carrier Verizon to get help and they told me I needed to go to Apple. So I am currently stuck because I haven't got anything to work.
iPhone 13, iOS 15
