Use scenarios
New message indication
This scenario shows how the new message indication result codes are handled.
Ensemble S15: GPRS/packet domain
Locked PDP contexts
In Sony Ericsson phones every PDP context has a one-to-one relationship with an Internet Account. If a
certain Internet account is locked, the corresponding PDP context will also be locked for editing. As a
consequence, an attempt to select PDP context parameters with AT+CGDCONT may fail even though the
CID of the context is within the range reported with the test command. The read and test commands in
this ensemble are not affected by these restrictions.
