While everyone is frustrated over continuous delay in launch of Jio 4g, some of us are actually enjoing the Jio preview offer which is unlimited for 3 months.
Jio network supports VoLTE for voice calling with preactivated HD voice quality. It allows us to enjoy unlimited voice calling to any network in the country. Voice quality is far better than any other mobile network. I have experienced the full extent of HD voice by using phone speakers instead of the earpiece. It works even with one bar signal at remote area, but anything lower than that could interrupt the conversation.
Before you lift your finger after dialling any number, it gets connected instantly.
Jio also allows us to make video calls to another Jio numbers.
Jio also offers a wide range of options to contact customer care support by using the email, chat and service request from the app. It has also got a toll free number which can be used to contact Jio Care from non-Jio numbers.
