My sister with a Cingular TDMA phone is visiting me, and in most areas her
Nokia phone has no signal. Nor is it switching to AMPS. OTOH, her son's AT&T
TDMA phone is working fine in the same areas. Both are Nokia phones, and
can't be forced to AMPS.

Usually this is either caused by a woefully outdated IRDB (Intelligent
Roamer Database), or by using an IRDB-capable phone old enough to have
manual settings (like a Nokia 5120- although you ca manually select
home/non-home type carriers, the IRDB will prevent the "wrong"
carrier's signal from being available.) Phones like these should be
in the "any system" mode.

What model Nokia phone is it?

Generally TDMA handhelds don't unless the only tower available is
AMPS-only (or CDMA/AMPS). TDMA signals from a given tower and no more
or less "strong" than AMPS from the same tower, so the phone will
generally hang on to TDMA until the proverbial bitter end.

Any chance mom's is dual-mode (800MHz AMPS/800 TDMA) and the son's is
tri-mode (also 1900 MHz TDMA)?

IMO, Cingular is not interested in TDMA only GMS.

If possible I would switch to GMS, cause TDMA (and AMPS) is going away
fast in the cellular world

I am sure that you mean GSM.

However I would expect TDMA to be about 5 to 7 YEARS before it goes away and
AMPS when the current restriction on keeping imposed by the government is
lifted. ( I can't remember the date ).

While TDMA may not go away for seven years, it many areas, it has
already deteriorated enough to chase people to GSM, and twill only
continue down that path.

I haven't noticed any deterioration in Atlanta, Memphis, Litte Rock, Chicago,
and New Orleans.

I am still able to place calls whenver I want with my TDMA phone.

YMMV

As the subject line says, we were discussing California, not your
carefully chosen other locations.

Good observation.

Too, TDMA and AMPS may be around for a few more years, but the
quaility has degraded much over the last couple of years, it will
render it for all intenets, unusable in many locales.
