    I have purchased 3T its awesome phone. I am facing one issue. I have Vodafone and JIO sim cards, JIO in SIM 1 and other in 2.

    If my data is ON in vodafone, there is zero signal in JIO and i can not make calls. But i keep data off of Vodafone then i am able to make the calls. Irrespective of JIO data is ON or OFF.

    MY Problem is if my Vodafone data is ON i should be able to make or receive calls on Jio.

    Pls suggest the settings

    That's impossible. Jio works over Data. Since you can only have Data on in one of the cards, if you enable it on Vodafone, Jio will not work.

    yeah Jio Calling works with the help of data connectivity. If you are not connected to internet or you have disabled data on jio. It is impossible to call.

    You dont need data to make calls on JIO..you just need a stable network..it will automatically make calls on VOLTE. Maybe there is a bug with your phone, try with customer care. Are you seeing VOLTE displayed on status bar?

    Let's see what happens when you change the simcard. Change jio from other cards and see what happens after connecting cellular data.

    In OP3T only the data sim has a choice for network type and the other sim is restricted to 2G. Jio doesn't run on 2G. So not possible.
    Your dad's phone must be dual LTE standby?

    The thing is that ONEPLUS 3T is not active 4g phone that means only 1 of the sim can work on 4g so when u enable data of jio other sim can switch to 2g or 3g band but when the data of other sim is enabled jio cant switch to 2g or 3g band as jio is only for 4g signal and that is why ur signal goes off.

    also it is a VOLTE phone so u dont nees to enable data for calling thats for non volte phones.

    You don't need to enable data. But Jio should be selected as the preferred sim for data usage. I had used jio sim in many devices it's the same with all.
    If you choose other sim Jio won't have signal.

    I recently bought my Oneplus 3t from hong kong and its a chinese model running on oxygen os 4.0.2 , Nougat. But i am facing some serious problem with my handset, i bought Oneplus 3t thinking it was VOLTE enable device but when i used my jio sim (which is using volte network) in India i am not being able to enable VOLTE in my device even though I switched the volte option (On) it is still not showing Volte. I am not being able to receive or call someone because of the VOLTE problem.

    try using jio in sim1 and set it as default for data, set network type to support 4g. this should turn VoLTE on as soon as network comes up. try a restart if necessary.

    One plus 3 is 4g compatible handset so even if jio data is off you can make voice call and one plus 3 both sim are supported with 4g network

    Don't do factory reset or anything. There's nothing wrong with your phone. OnePlus 3T including almost every other phone do not support dual SIM 4G simultaneously. Only one slot can access 4G at a time and that slot is the one on which data is enabled. When you enable data on Vodafone, it becomes 4G slot while other one having Jio becomes 2G/3G slot. As Jio is 4G only network, it can't fall back on 2G/3G and so, it simply looses connectivity. I am not aware of any phone in market which has dual SIM active 4G slots. Without it, Jio or any 4G only network can't work when data on other slot is activated.
