will a samsung sgh f700 work......?

My question is if a brand new unlocked Samsung SGH F700 will work on the T-mobile network... To be more specific... Will it work with the sidekick unlimited plan which is like 500 minutes and evrything else unlimited like txt, pic msg, IM and the internet all unlimited.... Will that type of plan work with the Samsung SGH F700 without any problems or restrictions?????
Because I just wanna get the phone and put my sidekick SIM in it and keep the same number....
