3.5 Connect to an Unsupported Operator
or to a Test Equipment
When inserting test SIM card or a SIM card from an operator that is not part of
the ones pre-configured and listed in Section 1.3 List of Supported Operators
on page 3, the modem will automatically reconfigure itself in standard mode
and reboot.
Notes:
• The mode can be checked with AT+SQNCTM?
• AT commands can be sent from the STMicroelectronics terminal using the
"atcmd" command
• This configuration will be persistent at reboot
Once configured in standard mode after reboot, the UE will scan the following
bands in that order:
1. B20, B12, B13, B8, B18, B19, B28
If no CATM cell is found on these bands, the UE will then continue scan-
ning the other set of bands.
2. B1, B2, B3, B4, B26, B5, B17, B25, B66, B14
Note: The first attach procedure can take some time due to the large
number of bands to be scanned. Once the UE has attached to a
cell, it will save its settings into memory and scan for this cell first
on the next attach to allow speeding up the connection.
