Literally you are correct. However in practice it is wrong....
I LOVE the idea of the SIM chip, however there seems to
be one common misconception about it. While it will transfer your phone
number to any phone you plug it into, sales reps also like to tell you it
will also transfer your phonebook as well. This is not entirely correct.
SIM's were designed a long time ago, and therefore the standard suffers a
bit when it comes to the data it can store. Newer phones will allow you to
store quite a bit of information about a contact. The information includes
multiple phone numbers per contact, email address, home address, etc. SIM
cards on the other hand were only designed to hold a name (only a certain
number of characters long) and one phone number (only a certain number of
numbers long).
So while you can copy your more advanced phone book to your sim card, it
jumbles the data when storing it. Truncating names to the set length the
SIM card was designed to have and only storing one number per name.
This can make some of the data in your phonebook entirely useless. An
example would be if you have a contact name Joe Blow with a cell number of
123-123-1234, home phone of 789-789-7894, work number of 456-456-4561, and
email address of joeblow@hotmail.com. When you transfer this users info to
the Sim card it come accross with a trunctated name, and looses info such as
whether a number was cell, work, or home. It will come across as Joe B
123-123-1234, Joe B2 789-789-7894, Joe B3 456-456-4561. The email address
is totally lost, as the SIM has no way of storing this information.
This can be particularly bad if you have multiple users with similar first
names, and it truncates their full name to only be part of their first name.
So now you have a bunch of first names and numbers, with no way to
differentiate whether a number was a work number, cell, or home number, or
even worse, which Joe you saved.
My example is a little extreme, as it will let you store more than 5 letters
for a name in the SIM, but trust me, I've experienced this before, and it
made all of my contact info almost useless. Its not nearly as cool as the
sales reps would
have you think, or as it could be today if they would just come up with an
update SIM standard.
