Default [Q] Hello transferring phones T-Mobile no contact into Vzw with contact

Hello, I have a friend who has 2 S2's, one is a working T-Mobile phone, but no contract, thus no data...she just uses it for music and pictures. Her other is a VZW S2 with her data plan, however the screen is shattered. Is there a way to get the T-Mobile S2 working with the VZW contract? Neither phones are rooted.

Thank you for any suggestions
