Hello, I am new here and plan on switching from Verizon to AT&T and getting an iPhone. Just about all of my friends are on Verizon however, and I'm wondering if there are additional charges when texting to different providers? I plan on getting either 1500 or unlimited text packages. Thanks for any help that can be provided. I've looked thru the AT&T terms and conditions, I do not see anything regarding this but I wanted to make sure before I switched.
