iPhone Sim network problem

Bro in my 13 pro max .i have 2 sim,one physical is jio and other e sim is airtel.
In my device my jio sim always when active it is in lte( this is default line). Then the airtel sim in able to get 5g,this is very inconvenient.so what can i do to get 5g in both sim

hi bro, airtel is not providing true 5G in many cities yet. its a work in progress. jio works in LTE network and 5G available in more cities. inside mobile data settings keep 5G ON and not in Auto. see for few days how it works.

If the network provides 5G in your area, it will start to work bro. till then mostly 4G or LTE only it shows.

Even jio is experiencing network switch in some areas. once they fixed the 5G starts to work after 3 or 4 days.
