I am no longer under contract at T-Mobile. I am planning to change carriers to Verizon. If I cancelled my T-mobile phone line let's say sometime next week would I still be charged for the rest of the monthly bill or would it be prorated? I was also planning on keeping my current number when I change carriers. I understand that I have to keep my T-mobile account active so that when Verizon brings my number over they will cancel my T-Mobile account? Can anybody else clarify this for me?
