    3G network issues with samsung SGH-F480

    I recently purchased a samsung SGH-F480. Thanks to this forum website I was able to enter the proper codes so it would work with my provider
    ( At&t ). However, the icon always shows as G network, and not 3G. Does anybody know what the problem is or/and how to fix it? My phone is 3G capable, so I know the phone should be able to do that. What can I do? Who is "in charge" of that: the phone or the service provider?

    Any information or help would be greatly appreciated!!

    Thanks so much!

    Although the phone is 3G capable, it only has the 2100Mhz 3G frequency which is used outside of the North America. North American 3G frequencies for AT&T are 850/1900Mhz so that is the reason your phone only displays the G for GPRS (and possibly EDGE as well). There is nothing you or AT&T can do to use 3G since it doesn't have the North American 3G bands.

    Another thing is it has the 900/1800/1900Mhz GSM bands of which only the 1900Mhz is used here in the US for AT&T and T-Mobile. Since you are using it with AT&T, you will have limited coverage without the GSM 850Mhz band.
    If you feel that you have to correct some of my posts for my capitalization of some of my words, then just bear with it. It's just a discussion forum where some may be limited by time to answer in well-versed and eloquent sentences.

    When asked if I see the glass half empty or half full, I responded I see just a glass of water.
    Now you know how I think.
