I know T-Mobile, as a company, doesn't offer much in the way of support to prepaid customers. However, I have a prepaid acct that I have had for probably 6 years (started w/ Powertel, taken over by Voicestream, then to T-Mobile) along with my post paid acct. I'm considering dropping my post paid acct for another prepaid. However, I wonder... will I be able to activate another line on my current prepaid acct so that I can get the airtime deals on a new line that my old line enjoys?
