mmcli [OPTION...]

       ModemManager  is  a  DBus-powered  Linux daemon which provides a unified high level API for communicating with (mobile broadband) modems. It acts as a standard RIL (Radio Interface Layer) and may be
       used by different connection managers, like NetworkManager. Thanks to the built-in plugin architecture, ModemManager talks to very different kinds of modems with very different kinds  of  ports.  In
       addition to the standard AT serial ports, Qualcomm-based QCDM and QMI ports are also supported.

              The default mode is ERR.

       -L, --list-modems
              List available modems.

       -M, --monitor-modems
              List available modems and monitor modems added or removed.

       -S, --scan-modems
              Scan for any potential new modems. This is only useful when expecting pure RS232 modems, as they are not notified automatically by the kernel.

       All options below take a PATH or INDEX argument. If no action is provided, the default information about the modem, bearer, etc. is shown instead.

       The PATH and INDEX are created automatically when the modem is plugged in. They can be found using mmcli -L. This produces something like (for modems only):

              Found 1 modems:

       In this case, the INDEX is 4 and the PATH is the entire string above.

       However, for the bearers, SIMs and SMS cases, the PATH is slightly different. The Modem is replaced with the object name in use, like Bearer. For example:


       -m, --modem=[PATH|INDEX]
              Specify a modem.

       -b, --bearer=[PATH|INDEX]
              Specify a bearer.

       -i, --sim=[PATH|INDEX]
              Specify a SIM card.

       -s, --sms=[PATH|INDEX]
              Specify an SMS.

       All of the modem options below make use of the --modem or -m switch to specify the modem to act on.

       Some operations require a MODE. MODE can be any combination of the modes actually supported by the modem. In the perfect case, the following are possible:

         '2G'  - 2G technologies, e.g. EDGE, CDMA1x
         '3G'  - 3G technologies, e.g. HSPA, EV-DO
         '4G'  - 4G technologies, e.g. LTE
         'ANY' - for all supported modes.

       -w, --monitor-state

              Resets the modem to its original factory default settings.

              The CODE provided is vendor specific. Without the correct vendor code, it's unlikely this operation will succeed. This is not a common user action.

              Send an AT COMMAND to the given modem. For example, COMMAND could be 'AT+GMM' to probe for phone model information. This operation is only available when ModemManager is run in debug mode.

              List packet data bearers that are available for the given modem.

              Create a new packet data bearer for a given modem. The KEYs and some VALUEs are listed below:

                'apn'  Access Point Name. Required in 3GPP.

                       Addressing type. Given as a MMBearerIpFamily value (e.g. 'ipv4', 'ipv6', 'ipv4v6'). Optional in 3GPP and CDMA.

                       Authentication method to use. Given as a MMBearerAllowedAuth value (e.g. 'none|pap|chap|mschap|mschapv2|eap'). Optional in 3GPP.

                'user' User name (if any) required by the network. Optional in 3GPP.

                       Password (if any) required by the network. Optional in 3GPP.

                       Flag to tell whether connection is allowed during roaming, given as a boolean value (i.e 'yes' or 'no'). Optional in 3GPP.

                       Protocol of the Rm interface, given as a MMModemCdmaRmProtocol value (e.g. 'async', 'packet-relay', 'packet-network-ppp', 'packet-network-slip', 'stu-iii'). Optional in CDMA.

                       Telephone number to dial. Required in POTS.

              Delete bearer from a given modem. This option explicitly uses a PATH to define the bearer, you can not use an INDEX to be deleted.

              Set allowed modes for a given modem. For possible modes, see the beginning of this section.

              Set bands to be used for a given modem. These are frequency ranges the modem should use. There are quite a number of supported bands and listing them all here would be  quite  extensive.  For
              details, see the MMModemBand documentation.

              An example would be: 'egsm|dcs|pcs|g850' to select all the GSM frequency bands.

              Set the preferred MODE for the given modem. The MODE MUST be one of the allowed modes as set with the --set-allowed-modes option. Possible MODE arguments are detailed at the beginning of this

              This registers with the default network(s) specified by the modem,

              Request a given modem to register on the network of the given MCCMNC (Mobile Country Code, Mobile Network Code) based operator. This code is used for GSM/LTE, CDMA, iDEN, TETRA and UMTS  pub‐
              lic land mobile networks and some satellite mobile networks. The ITU-T Recommendation E.212 defines mobile country codes.

              Request the status of ANY ongoing USSD session.

              Request the given modem to initiate a USSD session with COMMAND.

              For example, COMMAND could be '*101#' to give your current pre-pay balance.

              When initiating an USSD session, a RESPONSE may be needed by a network-originated request. This option allows for that.

              Cancel an ongoing USSD session for a given modem.

       All CDMA (Code Division Multiple Access) options require the --modem or -m option.

              Activate the given modem using OTA (Over the Air) settings. The CARRIER is a code provided by the network for the default settings they provide.

       All simple options must be used with --modem or -m.

              Run a full connection sequence using KEY / VALUE pairs.  You can use the --create-bearer options, plus any of the following ones:

                'pin'  SIM-PIN unlock code.

                       ETSI MCC-MNC of a network to force registration.

              Disconnect ALL connected bearers for a given modem.

              Display the status of the given modem.

       These options detail how to discover your location using Global Positioning System (GPS) or directly from your mobile network infrastructure (either 3GPP or 3GPP2).

              Show 3GPP based location information (MCC, MNC, LAC, CI).

              Enable location discovery using GPS and reported with NMEA traces.

              Disable location discovery using GPS and NMEA traces.

              Show GPS based location with NMEA trace information.

              Enable location discovery using GPS and reported with raw (i.e.  longitude/latitude) values.

              Disable location discovery using GPS and raw values.

              Show GPS based location information with raw values (e.g. latitude, longitude).

              Enable location discovery using the 3GPP2 network.

              Disable location discovery using the 3GPP2 network.

              Show 3GPP2 based location information (location of the CDMA base station).

              Enable location discovery using GPS but without taking control of the NMEA tty port.

              Disable location discovery using GPS and unmanaged port.

       All messaging options must be used with --modem or -m.

              Show the status of the messaging support.

              List SMS messages available on a given modem.

              Create a new SMS on a given modem. KEYs can be any of the following:

                       Specifies whether delivery report is requested when sending the SMS ('yes' or 'no')

                       Specifies the storage where this message is kept. Storages may be 'sm', 'me', 'mt', 'sr', 'bm', 'ta'.

              Use PATH to a filename as the data to create a new SMS.

              Delete an SMS from a given modem. PATH indicates the SMS path.

       All time operations require the --modem or -m option.

       --time Display the current network time from the operator. This includes the timezone which is usually of importance.

       All firmware options require the --modem or -m option.

              List all the firmware images installed on a given modem.

              Select a firmware image from those installed on a given modem. A list of available firmware images can be seen using the --firmware-list option.

              The ID provided is a UNIQUE identifier for the firmware.

       All OMA options require the --modem or -m option.

              Show the status of the OMA device management subsystem.

       --oma-start-client-initiated-session=[SESSION TYPE]
              Request to start a client initiated session.

              The given session type must be one of:

       --oma-accept-network-initiated-session=[SESSION ID]
              Request to accept a network initiated session.

       --oma-reject-network-initiated-session=[SESSION ID]
              Request to reject a network initiated session.

              Disable PIN request for a given SIM card. This must be used WITH --pin.

              Change the PIN for a given SIM card. It will be set to PIN. This must be used WITH --pin to supply the old PIN number.

       All bearer options require the --bearer or -b option.

       -c, --connect
              Connect to a given bearer.

       -x, --disconnect
              Disconnect from a given bearer.

       All SMS options require the --sms or -s option.

       --send Send an SMS.

              This option will store the SMS in the default storage defined by the modem, which may be either modem-memory or SMS-memory. To know what the existing default storage  is,  see  the  --messag‐
              ing-status option.

              This option states which STORAGE to use for SMS messages.  Possible values for STORAGE include:

                'sm'   SIM card storage area.

                'me'   Mobile equipment storage area.

                'mt'   Sum of SIM and Mobile equipment storages

                'sr'   Status report message storage area.

                'bm'   Broadcast message storage area.

                'ta'   Terminal adaptor message storage area.

              This option takes an SMS that has DATA (not TEXT) and will create a local file described by PATH and store the content of the SMS there.

       -v, --verbose
              Perform actions with more details reported and/or logged.

           $ mmcli -m 0 | grep SIM
           SIM | path: '/org/freedesktop/ModemManager1/SIM/0'

       And after that, you can just use the SIM index:
           $ mmcli -i 0 --pin=1234
           successfully sent PIN code to the SIM

   Simple connect and disconnect
       You can launch the simple connection process like:
           $ mmcli -m 0 --simple-connect="pin=1234,apn=internet"
           successfully connected the modem

       Then, you can disconnect it like:
           $ mmcli -m 0 --simple-disconnect
           successfully disconnected all bearers in the modem

   3GPP network scan
       Scanning for 3GPP networks may really take a long time, so a specific timeout must be given:
           $ mmcli -m 0 --3gpp-scan --timeout=300

           Found 4 networks:
           21404 - Yoigo (umts, available)
           21407 - Movistar (umts, current)
           21401 - vodafone ES (umts, forbidden)
           21403 - Orange (umts, forbidden)

   Creating a new SMS message & storing it
       Using the “sm” (SIM), you can do this using:

           $ mmcli -m 0 --messaging-create-sms="text='Hello world',number='+1234567890'"
           Successfully created new SMS:
               /org/freedesktop/ModemManager1/SMS/21 (unknown)

           $ sudo mmcli -s 21 --store-in-storage="sm"
           successfully stored the SMS

           $ sudo mmcli -s 21
           SMS '/org/freedesktop/ModemManager1/SMS/21'
             Content    |              number: '+1234567890'
                        |                text: 'Hello world'
             Properties |            PDU type: 'submit'
                        |               state: 'stored'
                        |                smsc: 'unknown'
                        |            validity: '0'
                        |               class: '0'
                        |             storage: 'sm'
                        |     delivery report: 'not requested'

           Successfully created new SMS:
               /org/freedesktop/ModemManager1/SMS/22 (unknown)

           $ sudo mmcli -s 22 --send
           successfully sent the SMS

   Listing SMS messages
       When the receiver gets all the parts of the message, they can now recover the sent file with another mmcli command in their ModemManager setup:

           $> sudo mmcli -m 0 --messaging-list-sms
           Found 1 SMS messages:
               /org/freedesktop/ModemManager1/SMS/0 (received)

           $> sudo mmcli -s 0 --create-file-with-data=/path/to/the/output/file

   GPS location status
       You  first  need to check whether the modem has GPS-specific location capabilities. Note that we’ll assume the modem is exposed as index 0; if you have more than one modem, just use --list-modems to
       check the proper modem index:

           $ mmcli -m 0 --location-status
             Location | capabilities: '3gpp-lac-ci, gps-raw, gps-nmea'
                      |      enabled: 'none'
                      |      signals: 'no'

       The output says that the modem supports 3GPP Location area code/Cell ID, GPS raw and GPS-NMEA location sources. None is enabled yet, as we didn’t enable the modem, which we can do issuing:

           $ sudo mmcli -m 0 --enable
           successfully enabled the modem

           $ mmcli -m 0 --location-status
             Location | capabilities: '3gpp-lac-ci, gps-raw, gps-nmea'
                      |      enabled: '3gpp-lac-ci'
                      |      signals: 'no'

   GPS location technology enabling
       We can enable the RAW and NMEA GPS location sources using:

           $ sudo mmcli -m 0 \
                        --location-enable-gps-raw \
           successfully setup location gathering

       If we do check again the status, we’ll see the GPS-specific locations are enabled:

             3GPP location   | Mobile country code: '214'
                             | Mobile network code: '3'
                             |  Location area code: '21071'

       An example of RAW GPS location information:

           $ sudo mmcli -m 0 --location-get-gps-raw
             Raw GPS         |  UTC time: '155142.2'
