Useful tip for switching LTE bands in the G710EAW (and possibly other versions)

[Falkentyne]

If you try to change bands in the service menu (e.g. from Band 4 to band 2) and you have LTE but phone calls don't work at all (just says call ended instantly), just go to "network mode" and select automatic, which will get voice working again on your new band.

Turning the sim card off and back on won't fix that--that will just make the band reset to default (with voice working) which isn't want you wanted if you were switching bands.

This can be useful on low tier providers if one band is lagging horribly and another band is more reliable.

I just recently discovered the service menu, does this actually enable bands that normally aren't active? I see Band 71 here which I thought was only available on the TMobile US variant, yet here I am with the ULM model and it shows it in the menu. I'd like to enable it in case I'm ever in an area that supports it, but I'm not sure what this menu actually does?
