I guess it depends where you are. I have to say at my shop t-mobile is the only carrier to work in the store.
And to be honest the only place I go that my phone does not have service is Kissing Bridge. And like I really want to be bothered there with phone calls anyways. But it must be reassuring to know that your CDMA phone is only good in N.America. If you plan on going over seas and want to borrow a phone from verizon, wait until you see what they want to charge you LOL* Better go take a loan out.
Again fuck Verizon the Nazis of cell phone service.
