No Data Service after Unlock [Q]

I successfully unlocked my 4G to use in Guam on a network that currently has the 3GS. I can make calls and receive texts..etc.. only problem is that the data isn’t working. it keeps telling me that data roaming is turned off and I need to enable it. is there another patch I need to get the data working ?
