2) The product is in automatic mode. It then tries to find the home operator and if found, tries to register.
If not found, the product automatically searches for another network.
3) 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 the currently selected operator. In manual mode, this
PLMN may not be the one set by the application (as it is in the search phase).
These commands are not allowed during one communication.
