Yes, Bcz Jio only works on VoLTE network mode and you select Sim 1 data Jio Sim network mode changes to 3G/2G so you will never get network on Jio if u uses other SIM data.. Thr is one solution u can work..You can manually change network mode of Airtel sim to3g/2g and select LTE for jio sim thn you will get the network in Jio..bt your Airtel data will only work on 3G no 4G/LTE..please let me know if this helps.. See attached snapshot..I am using Vodafone data and network mode for Jio is 3G/2G which will never work..
Thank you for your query. The relevant department may serve you better/speedily, if you can provide logs/video by registering this feedback in Error Section (Samsung Members App -> Feedback -> Questions/Errors -> Create -> Error reports).
Thanks guys.. For the response.. But What a silly limitation?? Not sure if I have to laugh at this or feel sad for buying so called premium. So issue would be same on Note 8 as well. There should be awareness on this limitation., at least for the people who is going to purchase.
