It will function and make calls, but you will not be able to connect to att's LTE network. The i9500 does not have LTE radios at all, AFAIK. Your best best for connecting to at&t LTE on anything that is not an i337 is either the Canadian(Rogers, etc.) i337M, or you might want to check the T-mobile gs4 forums to see if there is a hack to connect to at&t LTE.
