Microsoft’s new OTA adds 4G support to selected Lumia phones

phone2Microsoft India has started rolling out a new OTA (Over-The-Air) update to selected Lumia devices which allows them to latch onto the 4G network. The OTA unlocks the 4G support on a software level, which was hidden by the company, despite having the LTE hardware.


These smartphones will only support the FDD – LTE (1800Mhz) band but not the TDD – LTE (2300Mhz). Currently, Airtel 4G works on 2300Mhz band.




The OTA will add 4G support for the following devices :

  • Lumia 625
  • Lumia 735
  • Lumia 830
  • Lumia 920
  • Lumia 925
  • Lumia 940
  • Lumia 1020
  • Lumia 1320
  • Lumia 1520

If you own any of the above devices, then you can update your software to activate the 4G option. It is expected that Microsoft will unlock the 4G feature on more devices in the coming days.
