I had both Cingular GAIT and Verizon tri-mode phones. Pre merge both
worked anywhere in the nation. Post merger Cingular has decided to
phase out TDMA, AMPS leaving just
GSM coverage.
I cancelled my last Cingular contract after twice traveling out of
states having zero coverage. When this happens Cingular has no way to
restore service until you are back in their
GSM coverage area (another
state) to power cycle the phone. Customers no longer get voice mail and
you cannot forward your cell to another phone.
On the other hand a Verizon tri mode V710 still works in 22 states
including nonmetro/interstate areas.
The Verizon zip code service locator is always accurate. Check your
locations of interest to make sure they are in the enhanced service
areas. If not you may have to live with Cingular just do not assume the
phone will work outside their
GSM coverage area.
Even the companies own press releases confirm Cingular has the highest
complaint and churn rate. Also Cingular is adding net customer at a
lower rate than Verizon.
Summary from recent Verizon and Cingular and other press releases:
Verizon Wireless Q12005 results: 1.64 million net customers, total 45.5
million customers, churn 1.33%, and complaints 1.4 per 100,000
customers.
