Here's the short version: I switched from the Blackberry Torch on AT&T to the Samsung Galaxy S3 on Verizon. The Galaxy S3 drops calls like a motherfucker. I can't place calls or check voice mail from my house, which, ironically is two blocks away from the goddamn Verizon store. SO I gotta go back to AT&T. I'm within the 14 days window, so I should be all good. BUT how do I make sure I keep my cell number? Do I go to AT&T first and change back? Or go to Verizon first and cancel? Srs answers only.
