Mobile IP only. The mobile makes data calls only when Mobile IP is supported in the
network. During a MIP session, if the mobile hands off to a network that does not
support MIP, the mobile drops the session and informs the upper layers of the failure
(for example, by dropping DCD to a laptop).
Note:
When the AT$QCMIP value is changed to 1 or 2, the value of AT$QCMDR is changed to 3.
AT$QCMDR=3 means that the mobile tries Service Option 33 when it is in a cdma2000 network that
advertises P_REV6 or higher. When AT$QCMIP >0 and an attempt is made to set AT$QMDR to less
than 3, the mobile returns ERROR.
