    RUIM cards are SIM cards for CDMA. The capability does exist; the demand does not. Very few people regularly swap SIM cards. For the most part, people buy one phone, have one carrier, and that's what they stick with.

    There are CDMA world phones that will accept out-of-country SIM cards for using GSM overseas. The CDMA Pre3 is one such world phone. So there is absolutely no need to buy a GSM-only phone in order to use SIM cards while traveling.
    Touchscreens are a fad.

    WCDMA have this name because use the same technique as CDMA to transmit the data between the tower and the cellphones, and ONLY this.

    In rest, use all structure that came from GSM...

    Vivo's abandonment of CDMA in Brazil cannot be blamed on the lack of SIM cards for CDMA.
