I am trying to program a
GSM based machine-to-machine device. I am
supposed to "remove all phone numbers from the
SIM card" as well as
all received text messages. I deleted everything in the phone book
and all text messages (sent, received, archived,etc).
Next I am told "store at least one phone number into the
SIM card" and
I stored in the phone book one number without the name (and I verified
that the number is on the
SIM and not in the phone's memory.
Next "store four SMS-messages to
SIM card's 'own text messages'
memory". I think I have not succeeded with this. I am using 2
phones, and by switchin gthe
SIM card between the phones the only way
I managed to store SMS messages on the card was by sending SMS
messages to the phone.
I have not been successfull in finding information on "
SIM card memory
locations". Any help in finding some relevant information would be
great appreciated. TIA
