I was wondering if anyone has ever changed their rate plan online to one of the business rate plans. When I log into my account and go through the motion of changing my rate plan I have the option of selecting the business rate plans. My friend just switched his online and got the message it'll take effect at the start of the next billing cycle. Will Tmo contact him for a the Business Tax ID? The plan seems to be pretty good and I would like to switch also. T.I.A.
