Do SIM cards contain provider software?
|
|
| Sharp 2005-06-15, 10:55 pm |
| Hello,
I have a question about SIM cards.
Do SIM cards contain the provider software that is on the phone?
For example, if you had a Nokia 6010 and put a Tmobile SIM card in it would
you get Tmobile specific options like Tzones? Likewise, if you put a
Cingular SIM card in would you get Cingular specific options like Media Net?
Thanks for any info!

I do not think so, from what i experienced, it all depends on your cell
phone...
The sim card would have SOME things that are related to your provider,
but i do not think a sim card can contain allthose softwares and
options from its providers... Instead, the phone is able to contain all
these options since it has enough space to do so, where the sim card is
to activate these softwares

Hm so the features of the other provider do become available - it's just
that they were stored on the phone already but not activated?

Not in the SIM burned into the firmware most of the time.

The firmware on the phone? So if say Cingular & Tmobile both offer Nokia
6010 phones when Tmobile sends you the phone it also has cingular software
on it, but it's just disabled?

No, it has the settings in the firmware for either T-Mobile or
cingular. It's what the carrier specifies to the manufacturer.

The SIM toolkit can be used to run provider-specific routines from the SIM
card itself. This is sometimes transparent (for instance, after the
AT&T acquision, Cingular added ENS [Enhanced Network Selection] code to
both its SIMs and several phones in order to better control the selection
and display of tower identity.
Applications that are available for user interaction are not commonly
implemented by US carriers, but they are the norm in many other countries.
Numerous carriers have additional menus that are stored and implemented
FROM THE SIM CARD. These may include access to routines that program GPRS
settings to the phone, store and manage additional phone books, allow
management of credits on prepaid phones, link banking functions to cell
phones, manage callback arrangements for long-distance roaming services,
and the like.

Cingular and TMobile do not impement such functions in their SIM cards.
They could, however, if they wanted to ... perhaps, say add a function to
the SIM meny which would download GPRS and WAP settings in order to enable
your phone to talk to the respective carrier's data network without
manually entering settings, or having them transmitted via a web site
request.
