    I am facing issues with my new OnePlus 3 t ( 6 days old). VOLTE does not work. I have restarted the phone VOLTE appears on the top but unable to call.
    Am a bit disappointed with this. another major problem is battery life. I don't see any difference between my 1 year old OP2 and brand new OP3t.
    Hope there is a known fix for the same.

    Jio sometimes wont connect to some networks. Try calling some other number to check that or calling 3,4 times may sometimes get connected. I suppose its not the devices issue. Dnt knw about battery life.

    Also check with apn settings.. On my 3T it took some very odd apn settings by default instead of jionet and yet the internet was working.

    VoLTE working for me. Sim slot 1.
    But if you are talking about calling then, that is a long time issue. It has improved but the call quality is not good. Also, the data speed has reduced too.

    Help needed!!

    I am using Sim 1: Jio and Sim 2: BSNL. When data using Jio is selected. Everything works fine.(VoLTE display in notification bar). I can receive and make calls from both sims. But, if i choose data from Sim 2 i.e. BSNL. Suddenly Jio network goes off and i cant use Jio for calls.

    So i am still in confusion. What to say? Can't i keep Jio active while i am consuming data from BSNL?

    I have recently got OP3T (India), and have inserted Jio4G SIM in it. I am able to get 4G connectivity however I am not able to make and receive calls and text. When I have contacted JIO Support they have confirmed that OP3T is VoLTE supported I will not require Jio4GVoice App to make and receive calls and text.
    What could be the problem here, can someone please help?

    I have recently replaced my SIM (instead of messing up with my new phone more) and it started working, hence now I am suspecting that the SIM was having a problem rather the device itself. Sometimes SIM doesn't get activated for VoLTE services by the carrier (I have never got APN settings pushed to my phone automatically from my carrier) and we don't receive accurate APN settings that are really required for VoLTE/LTE.
    As soon as I have inserted the new SIM everything started working perfectly and even I have received new APN settings from the carrier which are required for VoLTE and LTE.
    I have tried this with another VoLTE enabled phone, my SIM didn't work in it and my friend's SIM worked well on my phone which made me believe that the SIM change would work and it really worked once I have replaced the SIM.

    I would suggest the same to you as well, to try your SIM in another VoLTE enabled phone to verify if SIM is working properly.
