My iPhone should arrive tomorrow.
I am currently a ATT member and have been for years. Furthermore, I am on a family plan with four other phones. I also have unlimited texting on my plan as well but it's only for me and not the other phones.
My question is with activating the iPhone, can I keep my current package and just add the 20 dollar data plan and that's it?
Any help will really be appreciated.
