ATT & T-Moblie are on GSM frequencies (radio & antennas)
Verizon and Sprint are on CDMA frequencies (radio & antennas)

It is my understanding that the radios are not compatible. Also individual carriers have unique frequencies. Although some US phones have some international GSM abilities, the frequencies are different from those in the US.
