    Red face SIM card for CDMA phones!

    Last month I read about a company in China that made a CDMA cell phone with a SIM card like GSM. The SIM is compatible with the GSM SIM! Is there somebody who knows about when it will be available in the Verizon network?
    Thanks

    It would definitly be nice is something like that exists but dont you think incorporating cdma and gsm into the same phone would be hard unless they make the phone big.
    Anyway I hope it isnt vaporware. I hear about a lot of stuff that ends up being vaporware

    Looks good. The removable chips will make swaping phones easier and it would be more like having a gsm handset

    thanx for the info

    Is it CDMA or wCDMA? wCDMA is suppose to utilize SIM technology.
    ...and yes, I've done a search!

    CDMA and wCDMA are 2 very different things ...

    CDMA is 2G tech .. and is what we are talking about

    wCDMA is 3G .. and an extension of the GSM standard .. not the CDMA standard! [common mistake]

    Actually, from what I read on the CDMA web site, it IS an extension of CDMA, GSM is based on older technology than CDMA, so to me it seems more logical that future technologies would adopt some kind of CDMA. But in the end, who really cares, as long as 3G works like it say it will

    wCDMA *is* based on GSM technology. With all the talk about CDMA and wCDMA, people fail to notice the "w".

    There is another emerging technology called CDMA2000. This one is based on current CDMA technology.

    wcdmc, is still cdma in the fact that it uses Code Division Multiple Access (like is-95), and not Time Division Multiple Access (like GSM)

    ok .. yes .. wCDMA is CDMA [as far as air interface is concerned], but it is GSM when it comes to the handset ..

    so like the SIM for [is95] CDMA phones .. it is the BEST of BOTH worlds!

    can we ALL agree on @least that ???

    But WCDMA phones can work in the GSM networks, like cdmaOne and cdma2000 that are pbackward compatible.

    One difference between WCDMA and cdma2000 is:
    cdma2000 basestations are sync to GPS, but
    WCDMA is not.
    There are lots of differences like chip rate, BW,... but both are based on code divition multiple access, the only practical way to have dynamic buad rate.
