I have a 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 4gSIM 4G. It was working fine till I was using Jio4gJio 4G as my LTE network and for mobile data as well, but when iI recharged my Airtel simSIM card and switched it to 4g4G, my Jio simSIM was disabled (Jio doesn't have 3g3G/2g2G connectivity). So it means iI can use only one sim as 4gSIM with 4G enabled.
On the basis of the device model, it support 4gsupports 4G SIM on both slots but not at the same time. It means it does have an SoC that can handle LTE networks on both SIMs so,.
My concern is, Cancan Samsung provide some update so that users can use both SIMSIMs as 4g4G (LTE) simultaneously?
