GAIT SIM Different from a Regular Sim?

Get a load of this.

I have a S/E T62u Gait phone with a sim. They finally started the soft
launch of GSM in my area, Louisiana. I have an unlocked T68 that I just had
flashed to the latest ROM. For two or three weeks I have been swapping my
SIM back and forth as I perfer the T68 but it won't work when I travel in
the swaps and Mississippi.

Well, a couple of days ago the T68 stopped connecting to the system. I
called the front line customer service rep and she said she could tell from
her system that I 'fried' the SIM. She suggested I may have removed the sim
w/o turning off the phone. She said the GAIT SIM was different and wouldn't
work in a regualr GSM phone.

Like I said, it worked for weeks. And how can my SIM be fried if my T62u
still works fine on all 3 networks? It's on GSM now and i can copy to and
read from the sim.

She told me to contact sells and they would sell me a regular GSM SIM?

Is this complete rubbish or what?

I guess i'll wait for them to offically launch and start selling GSM phones
and then try to get a new SIM?

(as an aside, i tried to get GPRS Internet Access between my T68 and my
bluetooth Palm T and it never would work (worked with T-Mobile). When I got
to level 2 or 3 support he told me my account was set up for a T62u. I
thought a SIM was a SIM and it didn't matter what phone it was in. He said
he changed my profile to a T68 but it still never worked)

I am not sure how to answer this question. The GAIT SIM card is
different from a standard SIM card. The GAIT card handles your phone
information for both GSM and TDMA. But it will work on a regular GSM
phone- providing no other active card was designated to that phone.
This is easy to tell. SIM ERROR or SIM FAILURE tells you all you need
to know. SIM FAILURE means that the SIM you are using has been
deactivated. SIM ERROR usually means that the SIM has not been
activated. You cannot have two SIMs active on the same phone number.
I know nothing about your other cell phone or bluetooth.

A GAIT SIM and a GSM SIM are the same. the difference is that when activated
on a GAIT phone, the SIM also stores some TDMA related information. A GAIT
programmed SIM should work on a GSM phone fine as you have noted. the GSM
phone doesn't know what to do with the TDMA info so it ignores it. A GAIT
phone with a GSM SIM is a different problem . depending on how it is set up,
it may work on GSM if available or may complain if stuck on TDMA as part of
the required SIM info is missing and the network wouldn't know what to do
with the ESN coming from the phone as it doesn't exist.

as far as data, I don't be.lieve GPRS is available on GAIT plans. as a
result, you will not be able to get GPRS to work on your T68 as the network
doesn't understand what is coming to it.

find a GSM SIM to try in your T68 to make sure it isn't fried. as far as the
tech changing your profile to the T68, that would make the TDMA side of your
T62U stop functioning.

basically, GAIT plan, no GPRS, GSM plan, no TDMA.

HTH, jim

Excellent info, Jim, Thank you very kindly. I was going nuts trying to get
gprs to work on the t68. I could get WAP via gprs to work however. at least
until the t68 stopped working. GAIT is a nice stop gap, but that's all it
is.

Actually, there's no difference whatsoever. The TDMA info is stored in
the phone and the GSM info is stored in the SIM. The key here is this:
your account has phone related numbers stored on it. For TDMA only
customers, there's just an ESN. For GSM only customers, there's an IMEI
and a SIM number. With GAIT's dual technology all three numbers are
present, so when you put your SIM in a phone with no ESN and a
mismatched IMEI you did the damage. The IMEI is, for the most part,
irrelevant, so if you were an employee, or had a "friend" there, you
could simply remove the ESN from your account and you'd be able to use
your T68 fine. However, some employees have been doing this in
preconversion areas and been told in no uncertain terms to cease and
desist. All I can say is be patient, and when the GSM rollout is
official just call customer service and tell them you'd like to change
phones from your T62u to your T68. Sorry it's not what you wanted to
hear, but at least you know.

K Mart,

Thanks for the expert response.

What 'damage' to you think i may have done? To the SIM or to the T68? The
T68 now does not work with the GAIT Sim, would you expect it to work with a
new Sim? The T62u continues to work.

Actually, when we activate a GAIT phone we record the ESN and SIM, not the
IMEI. Since we routinely take SIMs from GAIT and GSM phones and put them
into GSM loaners, I have no idea why the T68 quit working. We have many
customers that have their service on a GAIT phone, officially, and use GSM
phones most of the time, switching back to the GAIT phone when they travel.
The ESN is only read when in TDMA/AMPS systems. I've even had customers that
accidentally switched their SIMs between 2 GAIT phones and didn't know it
until they got into a TDMA area.

Why all that switching? GAIT works just fine as a GSM phone. I have no
trouble using it on GSM in GSM areas. There does seem to be some
distinctions. My SIM card says West Coast GAIT. I have not seen a
regular SIM card that is so specific. AT&T uses a blue color to
distinguish their GAIT from regular SIM. If you get a GAIT phone with a
white SIM several of your GAIT phone functions will not work. There are
already several reports of people who have come across this problem.
On the Technical side- a GAIT phone is designed to search for another
service when GSM is not available. Is this built into the SIM command?
The SIM card is firmware with software instructions, much like booting a
computer off a floppy disk. So how does this all fit together? It only
takes a few keystrokes to activate your SIM card- what all is going on
and what is the long or short term impacts?

I simply prefer my 'old' T68i with smaller size, color screen, and bluetooth
that i should be able to use with my Palm Tungstan T. The GAIT phone works
fine, but lacks those features.

Again, the SIM no longer works in my T58i after working for weeks. It never
finds the network, actually, it shows bars, but won't make or receive calls.

Cingular CS says i 'fried' the sim by swapping it back and forth. I guess
i'll ask them to give me a new sim and trash the T68u. But now i'm worried
about messing up my family talk plan as we have 4 phones. one thing right
after another.
