Suncom, now currently 800 MHz TDMA and *HAD* a cooperative agreement with
AT&T for 800 MHz TDMA coverage in SC. Namely, there was no AT&T 800MHz TDMA
coverage in SC, so AT&T customers roamed on Suncom here. To activate a
TDMA phone here in the state, it had to be with Suncom. Now since AT&T
(TDMA) is now Cingular and TDMA is diminishing everywhere in favor of
GSM,
Suncom's role and future outlook has also diminished.
No way will Suncom switch to 800MHz
CDMA in South Carolina, else it would be
suicide for them. Verizon or Alltel, both 800CDMA, are strong here in SC,
and would not form coop agreements with Suncom for sharing and roaming
800MHZ
CDMA.
What would happen with Suncom customers when they traveled outside the
state, then have to roam on Verizon or Alltel networks? Suncom native
coverage is only here in SC and maybe parts of NC and GA.
From what I read in these cellular newsgroups, even Alltel and Verizon have
fewer and fewer cooperative roaming agreements with each other.
The only way Suncom will switch to
CDMA here will be in the PCS portion of
the cell phone band (1900MHZ), and possibly form cooperative agreements with
Sprint/Nextel there.
Other wise Suncom will switch to 900MHz
GSM or 1900 MHz
GSM and compete with
Cingular's 1900MHz
GSM coverage here in the state (SC).
With this perspective, I would look for Sprint/Nextel to acquire Suncom in
the near term and convert the Suncom TDMA 800 network to
CDMA 1900 (PCS).
Might be a good time to buy stock in Suncom if its cheap.
