    Mostly because of both- excellent coverage with roaming agreements already
    in force for most of the country, and because AT&T at one time encouraged
    resellers as a source of revenue. (AFAIK, they no longer seek out reseller
    relationships, but entertain the existing ones out of contractual
    obligation.)

    Because they are rushing the switch to GSM, and not focusing on maintaining
    their once excellent reputation for coverage.

    Cingular is in a similar boat, but doing a better job staying afloat- they
    too are transitioning their TDMA customers to GSM. Unlike AT&T, however,
    Cingular has relied heavily on GAIT phones- TDMA/GSM/analog combo units-
    that allow their customers to reap the coverage benefits of the mature TDMA
    network during the transition, and aren't going out of their way to wrench
    TDMA phones out of customers hands- instead they are playing it much like
    the analog to TDMA transition- they aren't forcing anyone to switch, rather
    they "encourage" migration to GAIT by offering special rate plans available
    to GAIT customers only, and figure the average customer's propensity to
    upgrade phones every few years will take care of the conversion for them if
    only they are patient.

    AT&T, instead, pushed the "gee-whiz" of "mLife"- the wonderful advantages of
    GSM picture phones and GPRS data, long before their GSM coverage was ready
    for prime time, resulting in migrating customers losing a lot of coverage,
    and new customers wondering where the reputation for ubiquitous coverage
    came from.

    Hardly. Possibly W-CDMA / 3G technologies, but not CDMA itself

    IOW they DON'T have the best service. No one really cares what they
    used to have.

    And in at least one market, NYC, they never did have anywhere near
    best, or even excellent, coverage. It was more like "if you're not in
    a dead spot ("spots" being miles in diameter), and it's not a heavy
    usage time (like 5PM or the weather is bad), the signal doesn't suck
    too badly" coverage. Which is why they lost me as a customer years
    ago. And which is why they're losing customers in the NYC market to -
    believe it or not - T-Mobile.
