Happy to learn from you so if its possible please state the API as 'net-mode' only has 3 input parameters on a B525, this API doesn't support configuration of CA and/or separate upload/download bands on a B525
NetworkMode = Auto (0), 2G (1), 3G (2) or 4G (3)
NetworkBand = 3G band (default 3FFFFFFF)
LTEBand =4G Band (default 20800800C5)
Also the 'net-mode-list' API also confirms my comments above as it supplies the available options.
