    ?What device you are using?
    I was hoping to use the KEYone BBF100-1 device I just purchased.

    ?What OS or Firmware is your device running on?
    Android of some sort.

    ?What steps have you taken already to try to fix the issue?
    Attempted to search the Internet, provider websites, here, and comm with Sprint representative
    ?If the issues are with a certain app, what version of the app are you running?
    Are there any specific error messages you get? If so, what are they?
    n/a

    I am finding it difficult to wade through all the minutia/propaganda/upsales to gain a clear understanding.
    So far I am gleaning that the KEYone does not have the ability to transmit on certain cellular bands that carriers are (purposefully?) changing to.

    But the situation comes down to this, I will have a Blackberry, of whatever model, that has a Real QWERTY keyboard, or I will not have a cellular phone.

    Is there any clear and concise answer as to which U.S. Cellular carrier supports a Blackberry of said configuration?

    Thank you for the assistance.
    p.s. I sooo am missing my 9310 :'(

    The only Sprint BlackBerry that hasn't gone moldy is their branded KEYone; if you want to use a KEY2 BBF100-1 in America your best bet is a GSM carrier like AT&T or T-Mobile. Advanced services like WiFi calling or VoLTE might not be doable, especially since the BBF100-1 is an import in the United States, but there's no fundamental incompatibility like there is between any KEY2 and Sprint.

    If you meant the KEYone BBB100-1, the same applies.

    in speaking with Sprint, they stated that they no longer sell that branded phone.
    I will look into T-Mobile, as that is one I had forgotten about.

    actually.
    I just looked into T-Mobile's site.
    ZERO Blackberry devices offered, only the infantile handheld devices.

    Buying unlocked and BYOD is all you can do, unless you're a Verizon business customer and want the KEY2LE.

    So, thurask, if I understand you correctly, having an unlocked Blackberry of any type (KEY"x""y") I will be able to have phone/text service by going through T-mobile? no other carrier(s) support any form of Blackberry other than T-mobile?

    also, if my research is correct, the following bands are for KEY2 and T-mobile:

    KEY2 accessible bands (BBF100-2)
    ===================
    1(2100),
    2(1900),
    3(1800),
    4(1700/2100),
    5(850),
    7(2600),
    8(900),
    12(700),
    13(700),
    14(700),
    17(700),
    20(800),
    28(700),
    29(700),
    30(2300),
    38(2600),
    39(1900),
    40(2300),
    41(2500),
    66(1700/2100)

    T-Mobile supported bands
    ===================
    1900 MHz 2
    1700/2100 MHz 4/66
    850 MHz 5
    700 MHz 12
    600 MHz 71

    is my understanding that with the exception of band 71, that the KEY2 can/will be fully functional on T-mobile for voice & text? (I would that it were easier to actually communicate with T-mobile, but their site is most difficult to actually contact anyone.)

    Phone and SMS has the least hurdles on T-Mobile or AT&T; Verizon is iffy other than the KEY2LE BBE100-5 (i.e. the one they sell to business customers), and Sprint is a no-go.

    Advanced features like WiFi calling and VoLTE aren't guaranteed, although you have a better shot on T-Mobile with an unlocked device than on AT&T.

    And yes, the KEY2 has the full complement of T-Mobile's bands other than 71.

    Thank you thurask, you have helped clarify my understand on which carrier(s) and which version of the Blacberry KEY"x""y" to focus on.
    -5 on T-mobile;
    as the -5 and -2 are identical for the U.S. bands they operate on.

    although, in further research, I am finding AT&T has less expensive, single line, pre-paid cellular phone plans then does T-mobile,... /shrug

    Not really... I’m longtime AT&T multiline customer, 20+ years, that keeps emergency T-Mobile line on separate unlocked older device. Their prepaid and MetroPCS brands can be cheaper depending on usage.

    If you’re going to use Key2 or Key2 LE and T-Mobile gives you satisfactory coverage, you should be close in price within a cheap lunch value meal.
