Control Commands
Change NAM Selection +WNAM
Description: This command is used to request a change in the NAM (Number Assignment Modem) selection.
The modem supports up to 2 NAMs. However, if a NAM is not fully programmed, the modem will
not switch to the requested NAM. The default NAM for the modem is 1. The response to this
command is only OK, and there is no guarantee that the NAM will change. If the NAM selection
request is accepted, the unsolicited response +WNAM: <nam> will be returned.
Syntax: Command syntax: AT+WNAM=<nam>
Command Possible Responses
AT+WNAM=2
Note: Use NAM 2, if programmed
OK
+WNAM: 2
AT+WNAM? +WNAM: 1
AT+WNAM=? +WNAM: (1-2)
or
+WNAM: (1)
Values: <nam>
1 NAM 1
2 NAM 2
Notes: Verizon based modems propagate the new NAM MDN to SIP NAI, MIP NAI, tethered NAI, and
PPP user ID when the NAM is changed.
In addition, some modems are configured to support only a single NAM. This is carrier-dependent
and settable at the factory. When only a single NAM is allowed, NAM1 is the only supported
value.
Current NAM Change Unsolicited Response +WNAM
This response indicates that the current NAM has changed.
Syntax: Response Syntax: +WNAM: <nam>
Possible Responses
