Table 65. AT+WMBS Main Reponses
AT+WMBS Response
Description
+WMBS: 0, x
Mono band mode 850MHz is selected.
+WMBS: 1, x
Mono band mode extended 900MHz is selected.
+WMBS: 2, x
Mono band mode 1800MHz is selected.
+WMBS: 3, x

Where:
When x = 0, the band has not been modified since the last boot of the Fastrack Xtend;
When x = 1, the band has been modified since the last boot of the Fastrack Xtend, and will
have to be reset in order to take the previous modification(s) into account.
Refer to document [7] Firmware 7.4a AT Commands Manual (Sierra Wireless Software Suite

Use the AT+WMBS AT Command to change the band setting of the Fastrack Xtend and switch
between EU and US bands and vice versa. Refer to the following table for the list of AT+WMBS
parameters that can be used and their corresponding description.
Table 66. AT+WMBS Band Selection

When x = 0, the Fastrack Xtend will have to be reset to start on the specified band(s);
When x = 1, the band switch is effective immediately. However, this mode is forbidden while in
Communication mode and during the Fastrack Xtend‟s initialization.
