It's probably done using SIM Application Toolkit (STK). If so,
there's nothing you can do about it short of getting a SIM
without that application programmed in. To check, try someone
else's SIM (on a different network). If the unwanted
"functionality" disappears with another SIM, it's an STK
application.

It's surely more likely to be firmware customisation?! In which case, the
answer is yes :-) You can 'unbrand' your handset using da vinci
http://www.davinciteam.com - and use your w800 usb cable (or another cable)
to unbrand it.

Could be firmware, but it's been done with STK in the few cases
I've seen.

You don't really know do you? It _IS_ a firmware function and can only
be removed by debranding.

You're very confident. But as I said, extra logos, key
assignments and menu items can be implemented using SIM
Application Toolkit, and that's the way I've seen it done by
some telcos. And I've done enough STK programming myself to be
sure about the capabilities.
Please have a good look at GSM 11.14 for the technical details.

Someone has already told you how it is done. If you do actually know
different now would be a good time to prove it. Thinking out loud over
usenet is pointless and potentially embarressing.

Why? I know how to do it. I have a phone in my hand with exactly the
result that the OP asked for. It is one of many that I have debranded.
It is nothing top do with GSM, it is a firmware function. Can we stop
wasting bandwidth over a trivial point now?

My sincerest apologies, but the OP asked a question, which I

They've pointed out that it _can_ be done in firmware, and I'd
be silly to dispute something so obvious. But have not I
personally seen that sort of thing done with firmware. Now it
may well be that's because I buy phones outright, unlocked,
without SIMs, and without any tethering to a particular
carrier. Perhaps it's also because we operate in different
world markets.

Prove what? Under discussion is exactly the sort of task STK
was put into the GSM standards for. My proof of the
alternative mechanism is my reference to GSM 11.14, QED.

I'm not even a little bit embarrassed.

I'm not denying that, and I'm happy to take your word for your
"debranding" activities.
> It is nothing top do with GSM, it is a firmware function.
In many cases, apparently yes. But what about the telco selling
SIMs, and controlling aspects of the display and menus on
_whatever_ phone it's put into? They do achieve that you know,
and without write access to phone firmware. And you could
unsuccessfully try to "debrand" one of these phones until the
cows come home.
> Can we stop wasting bandwidth over a trivial point now?
I'm not the one who escalated this debate. To the extent that
it's trivial, you'll hear no more from me. What I hotly
contest however is the claim that any phone with visible
telco-specific functionality must be running "branded"
firmware.

Hopefully it all works out for you. Some of us learned
something in the process, and that's always a good thing.
It's irrelevant to your situation now, but for the record 2 of
my 5 active SIMs behave in a similiar manner when put into a
pristine STK-capable handset. The others don't.

How could a sim, something that can be used in any model or type of
cellphone, interact with the various operating systems and hardware that
it could potentially encounter and still replace a specific function on
a specific phone? I would be more inclined to agree that it would be in
the phone's firmware.
Curious though, as I also have a W800 although mine is not "branded" in
any manner. What I find intriguing is the possibility of reassigning a
dedicated function key to another single keypress function, say
switching Bluetooth on and off.
Have you done this?

David

Of course it is.

No. It would involve modifying firmware and loading it. I just know how
to replace one with another. Way beyond me. The shortcuts function gets
you there in 2 clicks - that's almost there!

As you ask, by the SIM running an STK application and issuing
the "GET INKEY" proactive SIM command to the phone (ME), of
course. To quote GSM 11.14:
"This command instructs the ME to display text and/or an icon
(see 6.5.4) and to expect the user to enter a single character.
Any response entered by the user shall be passed transparently
by the ME to the SIM."
It's just an ordinary STK tag-length-value (TLV) command, which
will run on any STK-capable phone with a suitable STK profile
when such a SIM is used.

To answer more generally and completely than my earlier specific
reply, it's done by compliance with standards and associated
specifications. GSM 11.14 requires that compliant handsets can
be (in part) driven by the SIM using an array of "proactive SIM
commands". Other commands allow the SIM to process and react
to those interactive commands.
Most GSM phones these days (Ericsson W800i included) are
compliant.
Some phones (notably Siemens) even allow STK commands to be run
from the serial port as an alternative, as if they were being
run directly from the SIM. Using STK proactive commands, I've
written netmonitoring software which shows many interesting
things not otherwise accessible, like distance to the current
serving cell (by reading Timing Advance), and the list of
neighbouring cells (with signal strengths) at any given time.
SIM Application Toolkit is very powerful - don't underestimate
it.

A little knowledge is dangerous. The SIM in question would not be
running any applications. Do SIMs run applications? How do they know how
to? Is it when the user presses a button? What logo and purpose would
such a button have? Where would that be stored then?

Way beyond the scope of this response. See SIM standards at ETSI.

Yes, there are some very good questions there from Pete. And
I'll be the first to say "I don't know" to some of them.
When running from the SIM, STK apps necessarily get tied up with
SIM security, some aspects of which is _not_ in the public
domain. And I personally don't have any SIM programming tools
as such with which to experiment.
As I said in another post, I have written a specific STK
application, but using the serial port and a very useful "back
door" provided by Siemens. So I'm up to speed on basic TLV
command syntax, but not how the whole thing gets embedded and
locked into the SIM.
