default is empty string.
In certain configurations, such as using SIMs that contain data in Elementary File EF-CBMID (Cell
Broadcast Message Identifier for Data download), less than six combinations may be available.
To access a SIM’s Elementary File data refer to command AT+CRSM.
• For <mode>=1: One CBM ID or range of IDs (e.g., “320-478”) default is empty string.
<dcss>
CBM data coding scheme specification
All different possible combinations of CBM data coding schemes (e.g., “0-3,5”). Using default empty string leads
to get all CBMs independent of their dcss.
A given <dcss> replaces any former value and is used for consecutive requests.
