why can’t they enable India cellular band frequencies to model A1976..
There are two immediately obvious reasons. (a) they can’t fit the extra hardware into the available space within the watch, and (b) there may be constraints from some national approval authorities who will not allow the device to support foreign radio bands not approved in their region. Having to manufacture different regional models is likely to have a higher cost to Apple, so you can be sure they only went that route from necessity.
The bottom line is that the cellular functions of a watch purchased in USA will only work in the North America cellular region. The watch will continue to work when linked to your paired iPhone, but you will never be able to use its cellular in India. There is no way the hardware can be modified to change this, everything is on one integrated logic board.
