[Q] Network Issue

[b14ckd34th]

Is it possible for my Sensation on TMobile..to gain access to ATT signal..My issue is this, when I'm at work I have a really terrible signal but any ATT user in my building gets great service..When I try to manually switch network it says not allowed, is there anyway around this?
thanks for any response

Sim unlock your sensation and then buy an att Sim card. But you may not get 3g or hspa as att 3g or hspa band is different from Tmobile.
