    Question How to tell which 3G/4GLTE band/frequency I am using?

    Using the brand new Galaxy S4 and was wondering if there is a way to tell which band (850/1900) I am using? Or with 4G LTE, could I see if I am using AWS or 700mhz anywhere?

    Dialing *#0011# doesn't really tell me much.

    *#0011# tells you on the first line.

    -Band 2 is PCS 1900
    -Band 5 is CLR 850
    -Band 4 is AWS 1700/2100
    -Band 17 is SMH Lower 700 Block B&C

    When on LTE it also shows "LTE DL BW" as 5 or 10 MHz so you'll know if you're in a 5x5 or 10x10 market.

    What about on an iPhone in field test?

    Not familiar with it. Can you show me a screenshot of it? If it's only Tx/Rx data, it'd be possible, but trickier.

    For iPhone:

    For LTE - (Make sure you're on LTE)

    1) Dial *3001#12345#* and hit “Call”
    2) Click serving cell info....download and upload bandwidth will tell you if you are on 5x5 or 10x10.
    3) Freq Band Indicator will tel you the band (17 if youre on lte). You may need to wait a while for it to appear (try have someone sending you an imessage during this, so it triggers the data)

    UMTS/HSPA+ is a bit different (Make sure you're on LTE)

    1)Dial*3001#12345#* and hit “Call”...
    2)Click UMTS Cell Environment
    3)UMTS RR Info
    4)Download and Upload frequency will tell you if you're on 850/1900 UMTS (9000s = 1900; Anything else is 850 -- I forgot those numbers since I'm in a 1900 market)

    If you're jailbroken you can get the App "Signal 2" -- which is an easier way to look at all this info (with maps of cell sites). I does not have all the information that field test mode does (like 10x10 or 5x5)

    Here is a sample screenshot of LTE in a 10x10 market on band 17 (700 MHZ)

    Mine show Bands 5 & 17. So does this mean I don't have 1900 3G and AWS LTE in my area? I do live in a rural area which might not need all that bandwidth?

    Not necessarily. A common practice is that the phone parks in 1900 and switches over to 850 under certain conditions and use.

    Not that I'm aware of - it could be something available tho, perhaps in the rooted world if not readily available on the market.

    There are also some DL PCS channels that use 04xx 05xx and 06xx numbering. As I type this my iPhone is on 512. This chart breaks down all of the bands for UMTS

    Yup you're right. Forgot about those as well. Can't update the post to let others know. But thanks for pointing this out

    This is another resource on this website I've used to determine which band I am on.

    Yea when that post was made I'm pretty sure ATT only had UMTS on PCS, cellular was still exclusively GSM which I'm sure was part of people's complaints with 3g at the time.

    Thanks for mentioning this! I had used Signal but it was broken on the 4S and up, I believe. Checked when I JB my iPhone 5 and it wasn't updated. Glad to see there is a new version. Buying now!
