    So, I have network unlocked Kyocera Brigadier using with AT&T service.
    It was working just fine until one day I mistakenly chose "Global" option under "Preferred Network Mode" in setting.
    Now, everytime when it connects to 4G LTE, communication stops working. I can't send SMS/MMS, can't call, nor data connection.

    I read from somewhere saying that Verizon sold their LTE device to be unlocked but LTE service is somehow locked to verizon.

    with 2 days of research, I found that there is hidden setting to choose "CDMA (PRL)" option to disable 4G LTE service.
    All the threads were based on Galaxy S3 and they were recommending to use either "Phone info" app or "*#*#4636#*#*" hidden menu....

    However, none of them works with Brigadier.
    I even rooted device to find "hiddenmenu" folder from root explorer to unblock 4636, but I could not find it anywhere....

    Has anyone successfully access *#*#4636#*#* menu differently?
