This command is used to read the customer service profile (CSP) from
the SIM. CSP is a list on the SIM, which indicates the services that are
user accessible. Each of the services has a related bit within the CSP.
The services are grouped into service groups, with a maximum of 8
services in a group. For each service group, a bit mask tells which
services are available (bit=1). Unused bits are set to 0.
