BittuKumar_UpluUiSTMD I had same problem when I updated my CMF phone with version 3.0 but again after updating new updates it’s working great.
4g performance when connected to a 5g network
Merged 1 post from About 5g network.
Merged 1 post from Can't Use 5g unlimited after finishing 2GB per day..
Same here
Same with me i face same issue can not use my 5g free data with my free data plan.
Bro you can’t get 5g unlimited data,beacuse smart 5g is enabled you can’t get 5g data .5g is show the bar.smart 5g feature is increasing battery percentage, heating issue less.so 5g connection is slow.if you want 5g unlimited please turn off smart 5g 
hadi_sh after turning it off still the issue remains I have tried it 2a is the worst purchase of ny life
Turtle_shell bro please restart your phone
hadi_sh brother I have tried everything possible steps like restart,resetting network setting, changing sim slots, factory reset nothing works funny part I have recharged a year of 5g data pack and after that 5g stopped working
