From my understanding you can only use an unlocked sprint iphone 5 on tmobile with edge network connection. Here is the info that I have found. 


  Sprint/Cricket/Virgin Mobile iPhone 5 can only be unlocked for T-Mobile / Simple Mobile and may only get Edge. It may also have issues with data/mms so you may or may not get internet or MMS (picture messaging). This is happening to some Sprint iPhone 5 devices and we are working on a fix. THERE ARE NO REFUNDS IF YOU HAVE A SPRINT iPhone 5 and experience issues with data/mms.
