Chapter 3 – Supported GSM/WCDMA AT Commands
High Speed HSPA-H4 AT Commands Reference Guide (Document S000483A) 115
The product enters into manual/automatic mode, and then tries to find an operator
as specified by the application (as in manual mode). If this attempt fails, it enters
automatic mode. If this is successful, the operator specified by the application is
selected. The mobile equipment then enters into automatic mode.
Note: The read command returns the current mode and currently selected operator. In
manual mode, this PLMN may not be the one set by the application (as it is in search
phase).
These commands are not allowed during communication.
