Do not know when Lenovo will provide VoLTE update for this flagship phone, in terms of software updates , Lenovo sucks, I do not trust them in these terms.
I will consider this point in future mobile purchases.
AnonD-510719, 17 Sep 2016vibe x3 support both band
http://www.devicespecifications.com/en/model/21fa3819Right, not only hardware support is enough. Software also needs to be updated to provide VoLTE support in Vibe X3. Saying that I see very less ray of hope.
Lenovo had previously made many false promises on software updates which they never delivered. After having experiences with junk OTA updates pushed by them, I do not trust them anymore. :(
Jio sim working with internet on vibe x3,but because off volte not supported by the software we can't calling hope so lenovo soon fix this volte support by software update.
Vibe x3 supports 850 band 4g Lte.so in future is there any chance to support volte via ota update??
RishiGuru, 17 Sep 2016Full Reliance Jio support is only possible if your phone supports two separate 4G bands:

Anonymous, 08 Sep 2016Vibe x3 support Jio sim??Full Reliance Jio support is only possible if your phone supports two separate 4G bands:
1) FDD-LTE 1800 -> Used for data in Jio
2) FDD-LTE 850 -> Used for voice (VoLTE calls)
The FDD-LTE 1800 is the most popular 4G band in India, all 4G phones old or new will support it. Hence surfing the Internet and using data with Jio sim can be done with any 4G phone available in India. But Reliance have introduced a new tech in India which for phone calls using VoLTE by using the rare FDD-LTE 850 band, which frankly was never before used in India and hence no manufacturer bothered to include in their phones.
Phones like my Lenovo Vibe X3 and Vivo X5Max being a generation old supports FDD-LTE 1800 out of the box, hence data works fine with Jio SIM. Newer generation phones like my Vivo V3Max supports both 4G bands, hence it has full support for Jio be it data or voice.
Reliance must have understood, nobody will change their phone so as to use their SIM. Hence they have created their own app which will record your voice in real time convert it into data and sent it at FDD-LTE 1800 as all older gen phones support them. So for calls using their app the newer VoLTE specific FDD-LTE 850 band will not be used.
I use this app with my Vibe X3 & X5Max and it works fine. But as someone pointed out earlier, you ALWAYS have to keep the data ON, so as to receive phone calls using Jio sim in Vibe X3 or X5Max. For me it is a big pain, as now I need to be extra careful as background data may get download and auto updates taking place which will only trigger higher phone bills!!!
Also you become the slave of this Jio app, your phone's native dialer won't work. Hence I use my Jio SIM only with my Vivo V3Max as it supports both FDD-LTE 1800 & FDD-LTE 850 bands and I do not need this Jio app anymore. So with V3Max the Jio SIM acts just like a normal connection.
Hope this helps!!!
