Alternatively you can use the SIM ID - the internal id number of the SIM card.
The SIM identity is via the ETSI GSM command "AT+CCID" The IMIE is via the ETSI GSM command "AT+CGSN" Some manufacturers use different commands to obtain these (the Siemens, for instance, uses AT^SCID rather than AT+CCID). >From memory the Treo is Wavecom based, in which case AT+CGSN should be available. I don't have any information regarding sending AT commands to a Treo via the Telephony API, although people are trying, as indicated by David Burns page on Treo data connectivity (link below). http://www.dugeem.net/david/work/gsm-data.html Chris Tutty -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
