yes API net-mode allows to change band and enable auto aggregation and forced aggregation (f.e 900+1800).
The Huawei B525 API
net-mode only takes three parameters (NetworkMode, NetworkBand and LTEBand).
NetworkMode can be 01 for 2G, 02 for 3G and 03 for 4G
NetworkBand is the value for the 3G band, when not in use it is set to 3FFFFFFF
LTEBand is the value for the primary LTE bands available to the router this is not anything to do with aggregation, when not in use its set to 7FFFFFFFFFFFFFFF
For example
if you want to lock it to only band 20 on 4G you would pass the following parameters
03, 3FFFFFFF, 80000
if you want to restrict/limit it to band 3 or band 20 on 4G you would pass the following parameters
03, 3FFFFFFF, 80004
