    So I just got my white galaxy s2 from ebay

    Here are the specs
    [FONT=Arial, Helvetica, sans-serif]Brand--------- [/FONT][FONT=Arial, Helvetica, sans-serif]Samsung[/FONT][FONT=Arial, Helvetica, sans-serif]
    [FONT=Arial, Helvetica, sans-serif]GT-I9100RWA[/FONT][FONT=Arial, Helvetica, sans-serif]

    [FONT=Arial, Helvetica, sans-serif]Family----- Line[/FONT][FONT=Arial, Helvetica, sans-serif]Samsung Galaxy S[/FONT][FONT=Arial, Helvetica, sans-serif]

    [FONT=Arial, Helvetica, sans-serif]Type------[/FONT][FONT=Arial, Helvetica, sans-serif] Smartphone[/FONT]

    So far the phone is great but there is one problem, 3G doesn't work on it.
    Now my previous phone was a Iphone 3GS and I'm not TOO good with computers...

    Wifi works okay, the phone part works great too but I have no 3G which is very lame...

    Can anyone else with an unlocked galaxy s2 help me out? It seems like I'm the only one with this problem online currently o_O

    I called samsung, and they told me Unlocked phones even bought from the US cannot use 3G or even 4G (is this even right? Seems so wrong;;;)

    I called AT&T and they said "We have no galaxy s2s so we don't know what to do ;-;"

    EDIT: Oh right, I'm in the states right now

    You possibly need to set up your apn settings. Settings, wireless and network, mobile networks, apn names. Then add the following info
    Name: AT&T
    APN: wap.cingular
    Proxy: leave blank Port: leave blank
    Server: leave blank
    MMSC: http://mmsc.cingular.com
    MMS Proxy: wireless.cingular.com
    MMS Port: 80 MCC:310
    APN Type: leave blank

    Data roaming is of no relevance to obtaining a data connection on your 'home' mobile network.

    I've been using a SGS II on AT&T since May. No problem with 3G or HSPA+. Try setting the APN as Shotgun84 suggests.

    There is a known issue with losing 3G connectivity.

    Samsung told me that the only way to fix it is to re-flash the phone (at a Service Centre).

    I had the same issue when I got mine. Either find some network settings off the internet or take it into your network retail store and ask them about the problem (what I did). They changed the settings there and then with no charge, and I walked out with not only 3G signal, but H+

    I don't doubt it, but the OP stated that he is in the US with AT&T.
  10. Can anyone please confirm if the GT-I9100RWA will work with at&t 3g and h+ ?
    I am looking to by an unlock version on ebay and would not be happy if all I can get is 2g. Please help... Thanks

    I faced a simmilar problem in India and after clearly looking at the sim card slot , I found that I inserted the SIM card in wrong direction. Please look at the sim card simbol and insert accordingly don't look at the shape of the sim card .
