I have some quick questions regarding number portability. My old cell phone plan is under my mom's name, address, and SSN. I want to keep the same number but I want to do my name, address, and SSN, which are all different from hers. Is this possible or do I have to keep the same info? This will be going from Alltel to Tmobile. Oh, also, my old account is not active, meaning I don't have a cell phone right now, but I called Alltel and they said they would hold my number for 6 months. My mom still receives bills from Alltel every month for $0.00. Thanks.
