Multi-Tech Systems CDMA Wireless Modem manual Roam Preference +WRMP, Command syntax AT+WRMP=mode

Chapter 6 – Network Service Commands

Roam Preference +WRMP

Description: The Roam Preference of a CDMA modem informs the MS whether it is allowed to roam on foreign CDMA networks or only allow operation on home networks. The determination of what is a foreign or home network is programmed into the PRL (Preferring Roaming List). This command simply enables or disables the capability of the MS to roam, based on the PRL configuration. If the setting is accepted by the MS, the value will be written to non- volatile RAM and persist after a power-cycle. After execution of the +WRMP command, the MS may change roaming states. The unsolicited result +WROM: <mode> will indicate the new state. See Unsolicited Result Codes in Chapter 3.

	Note: This command is not available in Sprint®. and Verizon. software versions.
Values:	The parameter values are the following ones:
	<mode>
	0: Home Networks only, as defined in the PRL (default value)
