India's mobile market has been growing at amazing speeds, but despite the phenomenal rate of tech adoption, there is still a lot of work to be done as far as market reach and network coverage. India's 4G LTE networks are still in their infancy, yet, their growing spread and popularity has prompted Microsoft to push a new update, enabling 4G on select India smartphones.
The said OTA simply enables 4G on a software level, which was hidden on a lot of units, intended for the local market, despite already having the required LTE modem. No official list of eligible devices has been shared yet and lots of user reports have been confirming support for a few models, like the Lumia 930 and Lumia 1520. Other viable candidates seem to be the Lumia 735, 830, 1320, 1020, as well as the new 640 and 640 XL and probably many others (feel free to correct us, if we are wrong).
At this point any user feedback on the matter is appreciated, so if you are in India and received an OTA in the past few days, then be sure to check under network settings and report back if you now have the new 4G and 4G only options.
