Nokia 7 Plus smartphone launched back in February but was crucially missing 4G VoLTE support on its second SIM card. HMD's Chief Product Officer Juho Sarvikas promised that the feature will come shortly with an OTA update and the day has now come.
And as promised, the Nokia 7 Plus is now receiving an update in India unlocking VoLTE on the two SIM card slots. The update is V2.22A version and along with the new functionality, it brings better system stability and some user interface tweaks. Google's security patch for May 2018 is included too.
During the launch of the smartphone, it was also promised that the 7 Plus will support face unlock in the near future, but that's coming in a different update.
