Every command issued to the Telit modules returns a result response if response
codes are enabled (default). The time needed to process the given command and
return the response varies, depending on the command type. Commands that do not
interact with the SIM or the network, and involve only internal set up settings or
readings, have an immediate response, depending on SIM configuration(e.g., number
of contacts stored in the phonebook, number of stored SMS), or on the network the
command may interact with.
In the table below are listed only the commands whose interaction with the SIM or
the network could lead to long response timings. When not otherwise specified,
timing is referred to set command.
For phonebook and SMS writing and reading related commands, timing is referred to
commands issued after phonebook sorting is completed.
For DTMF sending and dialing commands timing is referred to module registered on
network(“AT+CREG?” answer is
“+CREG: 0,1” or “+CREG: 0,5”).
