Windows Configuration; Overview; Verify Ema Enumeration - OptConnect ema Windows Networking Manual

After the MBIM mode configuration setting has been properly updated, reboot ema by issuing
the following AT command.
AT#REBOOT
This reboot is needed in order to allow the MBIM interface to enumerate on the USB3 port. The
success of this enumeration will be checked in Section 3.3.2.
4. Enable GPRS Network Attaching: In order to establish a data connection, ema must attach to
the General Packet Radio Services (GPRS) network. Issue the following AT command:
AT+CGATT=1
5. Disable the PDP Context: In order for MBIM mode to work properly on ema, the PDP context
must not be activated on the 4G LTE network. To ensure ema does not have an active connection
to the network, issue the following AT command:
AT+SGACT=<cid>, 0
where <cid> is replaced with "1" for AT&T users, and "6" for Verizon Users.
