4G not working in F2 pro,Help!!!


Oct 30, 2020
Dual 4G is not working in F2 pro aka Xiaomi K30 pro.I have installed Xiaomi.EU rom and clicked on dual 4g connectivity. When i turn on data on sim 1 , the 4g icon shows but when I turn data on in sim 2,4g icon doesn't show, instead it shows H+ which is 3G.
Help please how to use 4G internet data on both sim cards. I even tried swapping the sim cards still issue is same. Both sim cards are of the same carrier too.
