Jio 4G Preview offer: A month long test of VoLTE calling and Jio services, here is what we got

While everyone is frustrated over continuous delay in Jio 4G launch, some of us are actually enjoying the Jio Preview offer which gives unlimited 4G. Being a freeloader on Jio network, my data usage has already crossed 100GB and still counting. However, Jio is not just about super speed 4G internet and has got a ton of service to go along with it

VoLTE HD Voice and Video Calling

Downloads2

 

Jio 4G network currently supports only VoLTE for voice calling. As a part of Jio-LYF preview offer, Jio allows unlimited voice calling to any network in the country. Jio is the first operator in India to use VoLTE, in fact Jio 4G network would be the largest VoLTE enabled 4G networks in the world. This is at a time when global 4G players haven’t completely switched to VoLTE, Jio took a bold step to go with VoLTE for voice calling.

VoLTE calling experience on Jio was seamless most of the time. The call connection speed is almost instant. Before you lift your finger after dialing Jio care number, call gets connected. HD Voice is activated when calling Jio numbers and voice quality is far better than any other mobile network. To experience the full extent of HD voice I had to use phone speakers instead of the earpiece. VoLTE calling can be compared to the calling experience on Skype or Hangout, but without the delay. It works even with one bar signal, but anything lower than that could interrupt the conversation.

Jio also allows making Video calls to other Jio numbers. This is almost the same as native 3G video calling on older Nokia 3G phones. I’ve attached above the screenshots of my video call with Esmail, the call was overall smooth and easy to make, audio and video quality was pretty good. Some lag was noticed when calling from Jio Join App, video call from LYF to LYF was smooth without any lags for delay. My LYF Water 1 handset started heating considerably after 10 mins of Video call. Battery was also down 8% in 10 mins. Jio is able to deliver HD quality lag free video calling for the first time in India. This is something OTT players like Hangouts or Skype won’t be able to match given that the internet speeds in India are too slow.
