    What are the advantages or disadvantages of using 32k or 64k sim in the Treo 650 ?

    When I got my 650 I moved over the 32k sim that came with my 600. I am wondering of if any reliability performance for phone operation can be gained by going to a 64K sim.
    Unlocked 650 on Cingular
    SE HBH-660
    Firmware: 01.71
    Software: Treo650-1.20-ENA
    Hardware: A

    I'd like to know the same thing. I took the 32k SIM out of my Nokia and am using it in the Treo -- and whereas it's working well, I'm wondering if it's not working AS well as it could with something different.

    For me, the upgrade to the 64k SIM saved me from throwing my Treo in the garbage. . .see this thread. . .

    How do you tell the difference between the two types of SIM?

    all Cingular told me was that you can store twice as many contacts on the SIM

    HTC Inspire "4G"
    HP Veer "4G"

    I used to have a 32K SIM and had no problems with it. Remember if you change to 64K SIM, you can not go back to 32K.

    That's not true. I originally had a 64K then switched to 32K due to "Cingular" problems. And have since switched back (lost my 32K sim in a back up Nokia 6820). No problems with any of the switches.
