    I'm going to be roaming a lot, and I've gotten used to my 9930 (and love it) and don't want to have to switch to my 9700 when I travel.

    In which countries will the Verizon Wireless 9930 NOT be able to get 3G on a GSM network? I have unlocked it, and will be using a foreign SIM.

    Thanks

    The quote below from poster dougsorensen has some great information that I think will be useful to you.

    AT&T started using the World Phone label when they switched from TDMA to GSM. All this means is that the phone can work on several frequencies. All but the cheapest phones that they offer have quad band GSM (850 / 900 / 1800 / 1900) and tri-band 3G (WCDMA, sometimes called UMTS, 850 / 1900 / 2100). The GSM bands and the 2100MHz 3G band are the important ones for roaming. Any phone you buy that has these frequencies will get the "World Phone" splash screen and work nearly anywhere you go. I'm open to correction, but I don't think BB currenty sells a GSM phone that doesn't have these frequencies. Even the newer BBs on Verizon and Sprint have quad-band GSM and Tri-band WCDMA capability (stick to models 9800 and higher, if you want to switch to one of these carriers).

    If you are considering buying a phone and are concerned about international roaming, look up the phone model here Phone Scoop. The frequencies are the first spec listed in Phone Scoop. If the phone you are considering has the frequencies listed above, you'll get the same roaming that you currently enjoy.

    No simple answer. Need to look at the frequencies of networks in the countries you're traveling to and make note of the 9930's capabilities.

    9930

    Dual-Band: 800/1900 MHz CDMA/EVDO Rev A networks
    Dual-Band: 2100/900 MHz UMTS/HSPA networks
    Quad-Band: 850/900/1800/1900 MHz GSM/GPRS/EDGE networks
    HSDPA: 14.4 Mbps
    HSUPA: 5.76 Mbp

    If you are just concerned about voice, the GSM radio in the 9930 should work on any modern GSM network. If you are concerned about 3G because of data, the bigger issue will be finding a SIM provider that supports BIS data connections.

    I already have a solution for that, it's not going to be a problem.
