+## Modem Manager
+
+To get modem information:
+
+Firstly,
+
+`mmcli -L`
+
+to list the modems. For example, gives: /org/freedesktop/ModemManager1/Modem/**1**
+
+So the modem index to use at this moment in time is ‘1’.
+
+Then,
+
+`mmcli -m 1`
+
+You can check, in passing, your own phone number (`| grep own:`) and get the SIM index (`| grep SIM`)
+
+The output for the SIM index looks like: SIM | dbus path: /org/freedesktop/ModemManager1/SIM/**1**
+
+So the SIM index is 1.
+
+Finally,
+
+`mmcli -i 1`
+
+That will show you your IMSI, among other pieces of information.
+
+-i and -m are abbreviated forms of --sim and --modem respectively.
