Hello - I have been a AT&T customer for for over 10 years. I have swapped out countless phones with my SIM card to new upgraded phones. I just noticed when I checked my online account, it shows that I have an Iphone, so I cannot make any changes to my account. I am required to call AT&T to make any changes to my account. I changed the model on the website to my old phone, but it keeps updating back to the IPhone. Before, my online account would show my original phone that I had with my account. Now, it shows that I got an IPhone even though I did not go through AT&T to upgrade my hardware. Does the IPhone send out outbound traffic to AT&T? It's no big deal that they know because I have a active account. I just never experienced this before after many hardware changes.
