You can check if the router established connectivity through your selected band by going to Status -> Network -> Mobile. In the mobile information table provided, there is a line called Connected band. It shows the band the device is currently connected to which should also be the band that was chosen manually.

*Routers, which have LTE category 6 modems and higher, support a feature called carrier aggregation. It allows to combine data streams using more than one frequency band simultaneously into a single pipeline, which results in improved connection speeds. Bands for carrier aggregation can also be selected manually. Please note that, in order for CA to work, both chosen bands must provide acceptable connection parameters.

In this case, connection details shown in Status -> Network -> Mobile section also display a carrier aggregation status as dual, indicating that modem has established connectivity between two different frequencies.

gsmctl command is specifically used to communicate with the modem module of the router allowing to control and obtain information vis command line interface. The -A option means that the following will be an AT command. The “ AT+QCFG=“band”“ AT command is used for band configuration, in this case, setting speciffic bands. The meaning of the values:

Manual band lock can be a potential solution to increase mobile connectivity speeds by choosing the correct band. However, every different frequency band and their combinations should be tested to find, which bands give the best results. Besides, there are many variables that influence the performance of mobile connectivity and radio based communications in general. For example, in case of heavy cell tower loads, reduced speeds are expected and changing an LTE band will probably have no significant improvement. On the other hand, changing the type of service to 3G might have an effect. A detailed look at different factors impacting the speeds of mobile connectivity is provided in the website below:
