There's a SIM in the tracker. The SIM stores a list of SMS. Right?
So I'd like to be able to send an SMS from the tracker (for example to check the account), and get the list of SMS, and read an SMS from the list (or the whole list at once) or delete it or empty the list. As I said I'd like to be able to perform these operations over GPRS. That's it.
What else can "to manage the SMS list" mean?
To configure authorized GSM numbers a manual is enough.
