Default Update AT&T unlocked Galaxy S4 from 4.2.2 to 4.4.2

I have an AT&T unlocked Galaxy S4(bought in US, currently using in India).

I am not getting any OTA update.

Please, suggest me a simplest and safest method for flashing the OTA update.
Also let me know, if flashing the AT&T OTA update will make my device SIM-locked?

If you are sim unlocked don't worry that does not get changed. If you upgrade using AT&T rom you will get locked bootloader that is more of a problem if you want to flash AOSP rom you will force to stay on TW base roms. To upgrade use full NB1 thread on the general section.
