    Can someone explain what an unlocked phone is? I have ATT wireless service. Can I simply pop out my SIM card and insert it into any unlocked GSM enabled phone??

    An unlocked phone means that it is not locked to a specific service provider. You can stick in an active SIM card from any service provider and use the phone.

    If your phone is locked to AT&T, a T-mobile sim card will not work in the phone. If the phone is unlocked, then the T-mobile sim card would work.

    CDMA phones do not travel between CDMA providers well. While it can be done, it is not advisable as you will probably lose out on services and features on the other network. Why is this?

    CDMA phones are created with ROMs specifically for the network upon which they are used. The voice and data provisioning system, roaming indicators and many other features are totally Sprint- or totally Verizon-centric.

    Secondly the ESN number on your phone is a unique number in the radio that the network can see. If your phone falls outside of the ESN ranges allowed on Sprint, they will not allow the phone to be used. This seems to be enforced weakly.

    In summary, the main reason not to move a phone between CDMA networks is that you will be compromised on features and not be able to get support when something fails.

    Sprint(CDMA) has no sim card.

    What an answer! Either you're the CEO or the best little corporate citizen at palmOne.

    Thanks, but I just point folks to the Knowledge Library when I know it has an answer for a particular issue.
    As far as the next Treo is concerned, afraid I haven't heard either, sorry. But stay tuned to the palmOne site or your favorite forum, as news will travel fast.

    Sincerely
    Kevin
