You could try but if the AT&T in India uses the different model of GS4, you might not get the OTA. And sometime, they might use the different rom/software for the AT&T India.
AT&T in US use (SGH-I337) model which you have now.
You should ask this question to the AT&T store in India.
Galaxy S4 SGH-I337 NC1 baseband: GE 36 with SS
HTC Vivid : CM-11
Motorola Xoom Wifi : CM 11
