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 4 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 is no guarantee that the NAM will change. If the
NAM selection request is accepted, the unsolicited command +WNAM: <nam> will be
returned. If or when the actual NAM changes, the unsolicited command +WCNM: <nam> will
be returned. See Unsolicited Result Codes in Chapter 3.
