what is the best was to go about getting level 2 (advanced) support regarding Motorola phone using Visible in poor coverage area.

I have spent hours "chatting" and did not receive any help. I was told that the cell phone manufacturer was responsible for the issue, but the cell phone manufacturer informed me that VISIBLE is the one who does the particular thing that I need.

What I need is to switch my network band to be 4G LTE. According to the manufacturer, it is possible to do this, but VISIBLE has to be the one do it. It involves dialing *#*#4636#*#*, but the option is greyed out either by VISIBLE.

I need to do this because I live in a dead zone. It is bad for the phone for it to spend its entire life cycle trying and failing to connect to 5G, when that simply is not ever going to happen.

Thanks in advance.

[Note: unless you have a Motorola phone and have successfully dealt with this EXACT thing, please don't be suggesting apps for me to try.]
