    Dear all . . . may I ask if there is any tool available with which we could identify at what band (4G / 3G / 2G) our BlackBerry 10 devices are connected to carriers?

    Not sure if there's an app for that but you generally see that at the top right of the screen on BlackBerry Devices...
    4G LTE, 3G, EDGE, edge, etc

    There is an app that can display what bands your device is capable of using.

    Signal - BlackBerry World

    And as Bounce007 mentioned, the signal indicator on the screen will say the general name, LTE, 4G, GSM ect......

    Thank you very much for your prompt replies. I have been using Signal app on my Z10 and Z30 . . . I have also looked into escreen:// to see if there is any information related to the particular band (of 4G / 3G / 2G) at which my BlackBerry 10 devices are connected to carriers. As you have kindly mentioned, the current choice of LTE, UMTS, or GSM can be easily identified but there is no information related to cellular frequency bands.

    By frequency, do you mean Radio Frequency bands (measured in hertz)? I checked out signal and saw RF band information. Is this what you are looking for? (see below)

    Yes, I mean radio frequency bands.

    As you have kindly quoted a screen copy, the Signal app does tell us what bands are supported by our BlackBerry 10 devices. (Different models support different sets of radio frequency bands.)

    BlackBerry Q10 - Model Comparison
    BlackBerry Z10 - Model Comparison

    But the Signal app does not tell us at what band our BlackBerry 10 devices are currently connected to carriers.

    Get Device Suite, there is a free version. You can see which "network Technology" you are currently connected to. It might not be in Hz though

    Thank you very much for your kind suggetion but apps like DeviceSuite do not tell me the radio frequency band which is currently connecting my device to my carrier.

    Before someone also suggest to you to search for an Android app, I will warn you - no such exist even for android as I was looking for one just this past weekend. Some samsung phones seems to have it in the firmware but there is no universal app.

    And when you say "communist", perhaps you really mean fascist or Nazi... as in the Soup Nazi???

    Thank you very much for your kind message . . . may I ask what "Frequency Bands" (4 0130 8 08 displayed on my Z10 and quoted below) stand for in Network Info?

    Do they have something to do with UMTS frequency bands ?

    As the OP pointed out, Signal doesn't tell you the frequency band your phone is currently using.

    I have learned that UARFCN UL and DL channel numbers are listed in the following page of engineering screen. By consulting lists like UMTS-FDD Frequency bands and channel bandwidths I have figured that my Z10 is connected to the 3G network of my carrier at Operating Band 1 / Frequency Band 2100.


    escreen:// ---> 3GPP radio ---> Radio Network Info ---> Serving Cell (UMTS in the following example)

    I have learned that finding an LTE band # is more straightforward compared to finding a UMTS band #. In the following example my Z10 is connected to the 4G network of my carrier at Band 3 (E-UTRA frequency bands and channel bandwidths).

    By the way, EARFCN can be easily converted into frequencies by online calculators (e.g. EARFCN calculator).

    This is good info Yhamaie! But i am curious why did you need to know what frequency band your phone was operating on?

    But i am curious why did you need to know what frequency band your phone was operating on?
    My carrier has been offering 3G services at UMTS Band 1 (2100 MHz), Band 6 (800 MHz), and Band 9 (1700 MHz), which are supported by many BlackBerry 10 devices and legacy BlackBerry OS devices. So, I did not have to worry about UMTS bands and frequencies.

    My carrier has been offering 4G (3.9G) services at E-UTRA Band 1 (2100 MHz), Band 19 (800 MHz, which embraces Band 6), and Band 21 (1500 MHz), all of which are NOT supported by BlackBerry 10 devices.

    Luckily - albeit only in metropolitan areas - my carrier has started offering 4G (3.9G) services at E-UTRA Band 3 (1800 MHz) recently, which is supported by some BlackBerry 10 devices. This is why I presently pay close attention to LTE bands and frequencies. (Reportedly my carrier will start offering 4G (3.9G) services at E-UTRA Band 28 (700 MHz) next year, which is again NOT supported by BlackBerry 10 devices.)

    Which one is the band? I don't see it here it saying Band 1 or 2100 anywhere?

    In that HSPA screenshot, it's the first two lines, the UARFCN UL and DL. Those correspond to UMTS 2100.

    So you add them up to get the band you are using?
    What about the LTE? It shows 20Mhz

    Each UMTS band has a UL and DL range. For 2100 MHz, they are 9612 9888 and 10562 10838, respectively. So if you get a UL# and a DL#, you can match it against a band.

    For LTE, the third row from the bottom shows the band. 20 MHz is the channel (20x20 channel on band 3.)

    Would you please try UARFCN calculator (UMTS frequency and band) ? UARFCN UL 9738 and UARFCN DL 10688 point us to UMTS Band 1 and 2100 MHz.

    Band Name Uarfcn DL Downlink (MHz) Uarfcn UL Uplink (MHz)
