Force Electron to 2G mode

Is there a way to force the U260 to only use 2G?

I want to perform some battery testing and 2G is more critical than the defualt 3G mode.

Have you seen this thread?

If this doesn’t provide enough clues, you may want to look at the AT commands for the ublox module

Thanks but just selecting the band doesn’t control which service it uses. Does anyone know of an AT command that can do this?
