My understanding is that once blue always blue and once orange only orange.
The IRDB determines the phones choices and what order to access towers.I was
told by a very knowledgable tech that the customer is better of with the 32
K SIM cards than the new 64 K for this reason.

What you've heard isn't true. What I posted is correct.

Well what I have personally seen is that a individual that is balanced blue
and is in a location that only has orange towers is pretty much up a creek.
We can balance them to 1 network or the other but say in this situation if
we balance them orange and they get in a different location that is
predominately blue they will get very poor service.
I have seen thru MTI program a customer sitting on top of blue tower and
balanced orange and only getting 1-2 bars or the worst situation is the
phone may pick up the signal, say 4 bars, but the calls will drop because
there are so many people balanced blue that they get bounced off of the
tower due to the load balancing.

As I wrote, blue has free roaming on orange, and orange has free roaming on
blue. That doesn't mean that you will automatically get the better network,
only that you will get service.

With GSM, no connection is ever "bounced off" -- you either get a connection
or you don't. There is no dynamic "load balancing," only manual Homing to one
network or the other, and then only with ENS.

Read what I wrote more carefully -- it's correct.

Does what you've said "blue has free roaming on orange, and orange has free
roaming on
blue" also apply to TDMA or is it GSM only.

Thank you,

I should have made it clear that I was referring only to GSM -- sorry --
I don't know about "TDMA" (D-AMPS, IS-136).

I would assume the case is the same for TDMA, but as Cingular is working
to phase it out, they may just leave all those systems alone as they
migrate everyone to GSM.
