I have Samsung Galaxy On Max and inserted two different carrier SIM cards that are Jio4g and Airtel. It has been written that this device is dual sim 4g. It was working fine till I was using Jio4g as my LTE network and for mobile data as well but when i recharged my Airtel sim card and switched it to 4g my Jio sim disabled(Jio doesn't have 3g/2g connectivity). So it means i can use only one sim as 4g enabled.
On the basis of device model, it support 4g SIM on both slots but not at same time. It means it does have SoC that can handle LTE networks on both SIMs so,
My concern is, Can Samsung provide some update so that users can use both SIM as 4g(LTE) simultaneously?
