It looks like the T-Mobile and AT&T Galaxy Note II’s are pretty much identical: They both use the Qualcomm 9215M network chip. It makes sense for Samsung to create one phone without drastically modifying it for each carrier. The side effect is of course that the T-Mobile Note II is capable of LTE connectivity. Sounds great, right?
Well, the first thing you should remember is that T-Mobile doesn’t have an LTE network, and it won’t for a while. Second, T-Mobile disabled those radios anyway, so even if we wanted to use them on AT&T, we couldn’t. Maybe some hackers could find a way, but for now, there isn’t one.
Still, there is the possibility that T-Mobile will unlock access to those radios with an OTA update when their LTE network is finally out. That would be a fantastic move, and would future proof the device for quite a while. But no matter what happens, this is some interesting news and a good look at how little Samsung modifies their phone for each carrier.
