- Data coding Scheme as defined by GSM 3.38 – in numerical format
The DCS is an 8-bit parameter reported as an integer, the default value is 0, otherwise
for simplicity, we report only the most useful DCS, for further Schemes refer to GSM 3.38

1 0 - Class 2

TIP: The default value for DCS = 0 represents the default SMS sent by a mobile. If you don't
need any particular data coding scheme use DCS=0.
NOTE: Not all the DCS combinations described in the GSM 3.38 are supported, both by the
network and by the Telit GE863-GPS. Some features may be not implemented at network level
or at device level, resulting in a +CMS ERROR: 303 (operation not supported) result code. If
this happens then use a different DCS.
