Selecting GSM frequency bands BGS2 Terminal | Telit Cinterion IoT Developer Community

I am working on a project where I am using the BGS2 terminal to upload data to an ftp server.
Everything works fine, but now the question comes up which frequency band did I use for my connection.
I have searched in the "at command set" datasheet but I have not found the answer.
I just want to know which frequency band uses the module, 850/900 MHz or 1800/1900 Mhz?
Is there a command to select one of this?
Thanks in advance!
You can determine the band by ARFCN which you can get with AT^MONI command. The problem would only be with 1800 and 1900 where the same channel numbers are used. AT^SNMON can return the radio band, but this is a command which monitors all the network.
But there's no way to select the radio band in this module.
And with AT^MONI i get the current frequency band?
Is the moduke switching between the upper and lower frequency bands, or does it sty fixed in one of them?
AT^SMONI displays the serving cell parameters. One of them is ARFCN (Absolute Radio Frequency Channel Number) of the BCCH carrier. This number is specific for the particular frequency band. You can find the mapping tables on the internet.
The module can use all the bands that are available for the operator and it is under the control of a network.
