Automatic A or B

    How do you know which you should be on? Is it due to your area, or
    tri-mode/vs/digital only?

    Thanks.

    This does not really make any difference since the Preferred Roaming
    List (PRL) is what the phone uses to decide what carrier to use, and
    in which priority order. The "Auto A" or "Auto B" is only when you are
    roaming and encounter a system that is not in the PRL. (This is only
    for 800 MHz based systems) - which is rare these days.

    Typically you would set this to the same side where you have your
    native service, since when you roam the system you roam would need to
    have your phone number in their database as an allowable number to
    roam on their system - and is typically on the same network where you
    have your native service.

    However, if your native Verizon Wireless area is in the 1900 MHz PCS
    band (e.g. Milwaukee, Gulf Coast region), that makes the above
    paragraph a moot point, but *typically* Verizon Wireless service is on
    the 800 MHz "B" side across the country.

    If you want to learn about PRLs and how they work, look here:

    Thanks, Dave. I mainly was curious because when I had the LG VX8100, it was
    set on A, but my Moto E815 is on B.

    When it was set up many years ago the wired-carrier which
    also furnished cellular was automatically placed on the "B"
    side of 800 Mhz and the non-wired carriers were assigned
    to the "A" side. Now in general with digital being emphasized
    and analog going to be phased out it's hard to say except that
    some non-wire carriers have been picked up by wire-carriers
    and it's not predictable. My V710 scans first to digital via
    prl and then to 800 Mhz first to the prl and then to the other
    side be it A or B..Watch for the "roaming" triangle because
    your phone may connect to a non-VZW analog side..Luck

    Roaming has nothing whatsoever to do with analog vs. digital. There are
    preferred (free) roaming partners that are analog-only, and digital ones
    that aren't. VZW provides both analog and digital service wherever it
    has 800MHz (cellular band) service, and sometimes your phone won't be
    able to lock onto the VZW digital signal and will pick up the VZW analog
    signal instead, and that's fine. This roaming = analog thing is a
    holdover from the former SprintPCS policy of disabling digital roaming
    on their phones, so their customers would think that that only they had
    "pin-drop" digital.
