Microsoft is paying a bit more attention to India as its mobile efforts are gaining some attraction in the area. Last week we reported on Lumia 830 phones in the region finally receiving Windows Phone 8.1 Update 2. At the time of the announcement, a firmware update snuck in alongside Update 2 to a few other Lumia models. Without an official changelog accompanying the mysterious firmware bump, we were subject to reporting on rumors and anecdotal stories of various Lumia 930 and 1520s suddenly receiving 4G connectivity in India.
Fortunately, Microsoft India is offering some clarification on the firmware rollout. According to reports coming out from Microsoft India captured by wmpoweruser, the firmware does indeed enable 4G connectivity and is now being rolled out to a much broader range of Lumia devices. The update adds support for FDD-LTE (1800MHz) connectivity and future Lumia devices in the region will include support for TDD-LTE (2300MHz)
The new list of 4G enabled Lumia devices in India now includes:
Users who already possess 4G enabled SIMs may notice the update waiting for them. Similar to previous updates, owners of these devices can check for a phone update under their settings menu. As the firmware update is an Over the Air (OTA) rollout, users should be aware that it may take several hours if not days for the update to propagate.
