Post One Ui 8, my phone only connects 1 Sim at a time to 5g network. The 2nd sim moves to 4g network. Also, Vonr option is shown only for one sim which is used for data. However this was not the case with one ui 7. Both Sims were connecting to 5g at a time. Network preferred is 5g for both Sims even now. Not use if this is a bug or intentionally done.
