that is what i meant, this 7100 is not a 4G phone, another word, if you get t-mobile 4G prepaid plan with this 7100 phone, i don't think you will utilize t-mobile 4G speed but only at 3G speed.
I'm not sure entirely, but depending where you live you may be able to get tmobile's 4G. But the HSPA+ variety and not LTE. Some cities have been re-farmed and are using AT&T's band but I don't know if this phone will take advantage of that.
My best guess is don't buy this phone to use on t-mobile. At this point look for a LTE phone that works with tmobile's LTE.
I've blacklisted rebates! Except eβates, they blacklisted me!!
