It does if you want to transfer your number.You can switch your service at anytime. Your contract does not need to end for you to switch to another service. You will just have to make the payments on the contract until it is ended, but it doesn't prohibit you from using another service.
And there lies my problem.It does if you want to transfer your number.
I don't remember what the exact date was that I signed the contract and I'm not overly sure where the paper work is to go look...Did you sign your contract on August 5th, 2005 [2yr] or 2006 [1yr]?
If so, you ought to be able to change on the 5th this year, as technically that is 1 day beyond the contract date. That whole 'which is the real millenium year' argument again...
Yep, it's been possible for the past few years to keep your number when you switch carriers. It's called number portability. You can also port a landline number to a wireless carrier, but I think that's a bit more involved. Wireless->Wireless ports usually only take a couple hours. It's definitely one of the only few good things the FCC has doneDidn't know that. When I changed providers I just got a new number. Didn't think of transferring a number over.
