❓ Help How to Engineering mode to change Bandwidth for realme 5i

[alektit02]

Heyyy mga paps, I wanna asking a question because i can't find the bandmode itself of my realme 5i but I found engineering mode(#899#) but didn't have bandmode there. So anybody knows about the engineering mode in realme? Except po sa 899#.
