International Mobile Subscriber Identity (IMSI) +CIMI
Execute command returns the value of the Internal Mobile Subscriber Identity stored in the SIM without
command echo.
Test command returns OK result code.
Syntax
Command Command type
AT+CIMI Execute
AT+CIMI=? Test
Notes

Multiplexing Mode +CMUX
Set command enables or disables the 3GPP TS 27.010 multiplexing protocol control channel.
Read command returns the current value of <mode>, <subset>, <port_speed>, <N1>, <T1>, <N2>, <T2>, <T3> and
<k> parameters, in the format:
+CMUX: <mode>,<subset>, <port_speed>, <N1>, <T1>, <N2>, <T2>, <T3>,<k>.
Test command returns the range of supported values for <mode>, <subset>, <port_speed>, <N1>, <T1>, <N2>,
<T2>, <T3> and <k>.
