Well, if this will help you out, if you have ATT, you get NO reception inside of drexel. If you have verizon, you have 5 bars.. I don't know the difference between the 2 ATT services, but I can't imagine it's going to be remarkably different. If you choose ATT and decide to attend drexel (which i notice you are), you do so at your own risk. Verizon is without a doubt, better no matter where you go and has plans that are comparable to all ATT plans. All I know is that all the people who have/had ATT, have all been frustrated (and we even tried to get a petition to drop our contract w/o penalty, which obviously didn't work) and dropped our plans. I repeat, ATT sucks and I wouldn't take your chances with any "fancy" or "upgraded" ATT service.
