Where would I get the firmware? Can you link me to it?

I have the GT-I9300, but the area around my house has terrible reception. My roomate has the T-Mobile version of the SIII, I believe it is the T999, and it has wifi calling, which lets him use it even in the basement. Is there a way for me to flash T-Mobile firmware, or somehow add wifi calling...
