    I'm not really familiar with SMS standards, but is it possible for someone on a CDMA network (Sprint w/ Treo 650) to SMS someone else on a GSM network?

    Supposedly, not consistantly.

    I've sent lots of sms to a TMobile phone with no problems on my cdma 600. Have not done it on the 650 but I'd think should be the same.

    SMS is SMS, phone, alphanumeric pager, etc..

    Interesting. In the past I've tried SMS'ing friends in Asia who are on the GSM network, and they've tried SMS'ing me (Sprint CDMA), but we've never received each others messages. Has anyone tried SMS'ing people in different countries on different networks successfully? TIA.
