iPhone 7 Plus does not switch to 3G while making calls. It now stays on 4G. This means VoLTE has been enabled for many users in Mumbai.
For iPhone, there was a Carrier Settings Update and after that, under data options, the option to make calls on 4G appeared. That option needed to be selected to enable VoLTE calling.
Several people having Xiaomi Mi Max 2 and few on S7/S8 are also reporting this to be working.
VoLTE call from Airtel to Jio was instantaneous. That's some good shit right over here.
