5.13.1 Locked PDP contexts
In Ericsson phones every PDP context has a one-to-one relationship with an Internet Account (for more
information please refer to the
command in ensemble S20). 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
• AT+CGQREQ or
• AT+CGQMIN
may fail even though the cid of the context is within the range reported with the test command.
To find out which contexts that are locked, use the
read command.
The read and test commands in this ensemble are not affected by these restrictions.
