Mobile Status page

The following table describes the fields on the Mobile Status or Mobile Information page.

In general, all of the status fields in the page may display for either GMS or LTE cellular modems. The status fields display depending on the modem type, service, or registration or connection state.

Manufacturer The manufacturer of the cellular modem.
Model The manufacturer’s model number for the cellular modem.
Revision The manufacturer’s version number for the software running on the cellular modem.
Serial number The manufacturer’s serial number for the cellular modem.
Phone number

The phone number stored on the SIM. The SIM may not have a number stored, or it may not be correct.

SIM IMSI The International Mobile Subscriber Identity (IMSI) for the SIM card. This value is the account number for the mobile subscriber.
SIM ICCID The Integrated Circuit Card Identifier (ICCID) for the SIM card. This value is the serial number of the SIM card.
SIM PIN status

Indicates the lock status of the SIM. There area many possible status values. The most common status values are:

  • READY: SIM is ready. The PIN was entered or no PIN is required.
  • SIM PIN: A PIN is required to unlock the SIM. You can enter the PIN from the Mobile Configuration page.
  • SIM PUK, SIM PIN2, SIM PUK2, and similar codes: The SIM is locked and cannot be unlocked by the XBee Industrial Gateway cellular device. It must be placed in another device or phone to be unlocked.
  • Error: Either the SIM was not inserted or there was another SIM problem.
SIM slot index

This status only appears for products that support multiple SIMs. Indicates which SIM slot is currently in use by the device.

  • 1 means the first slot.
  • 2 means the second slot.
Signal strength

Received cellular signal strength indicator (RSSI) for GSM. A measure of the signal level of the network.

Different RSSI levels are used by GSM to determine the number of bars.

  • For GSM: -108 or more is 1 bar, -93 is 2, -77 is 3 bars.

Reference Signal Received Power (RSRP) for LTE. A measure of the signal level of the network.

  • For LTE: -118 or more is 1 bar, -106 is 2, -90 is 3 bars.
Signal level

The number of bars indicates the strength of the received cellular signal.

  • 0: No signal
  • 1: Poor signal
  • 2: Adequate signal
  • 3: Good signal
Signal quality

An indicator of the quality of the received cellular signal, measured in dB. This value is also known as Ec/Io.

Registration status

The status of the cellular modem’s connection to a cellular network.

  • Not registered
  • Registered (Home network)
  • Searching for Network
  • Not Registered (Access Denied)
  • Not Available (Reason not Known)
  • Registered (Roaming)
Cell ID Identifier of the cellular base station with which the cellular modem is registered.
Location area code Identifier of the location of a group of cellular base stations with which the cellular modem is registered, in hexadecimal format.

Mobile country code

Identifies a mobile phone operator/carrier with which the cellular modem is registered.
Mobile network code Identifies a mobile phone operator/carrier with which the cellular modem is registered.
Operator name The name of the mobile operator with which the modem is registered. This corresponds to the mobile country and network codes.
Band

The radio frequency band used by the modem.

LTE can use one of the following bands:

  • Band 2
  • Band 4
  • Band 5
  • Band 13
Service

The type of data service provided by the cellular network. For LTE, the data service is one of the following:

  • None
  • 1xRTT
  • EVDO Rev 0
  • EVDO Rev A

Future cellular modems may have other values.

Channel Radio channel being used by the cellular modem.
Profile

The current set of mobile configuration settings used to configure the cellular modem. XBee Industrial Gateway cellular products always use profile 0.

Connection state

The operating state of the cellular modem. The possible states are as follows:

  • Initializing: Resetting and configuring the modem.
  • Registering: Searching for the modem's cellular network.
  • Delay before connecting: The modem delays after an unsuccessful connection (Verizon only).
  • Connecting: Establishing a mobile data connection.
  • Connected: Established an active mobile data connection .
  • Disconnecting: Ending the mobile data connection.
  • Disconnected: Ended the mobile data connection. See Disconnect reason for the cause.
  • Disabled: The mobile data connection is disabled in the configuration settings.
  • PRL update: Updating the preferred roaming list (LTE only).
  • Operator scan: Searching the modem for available mobile operators (GSM only).
  • No device found: The modem is not available or is malfunctioning.
Connection duration Amount of time the current mobile data connection has been active. The format is N days HH:MM:SS.
Connection error

This status appears only after a connection error occurs. The possible reasons the previous connection attempt failed are as follows:

  • SIM PIN required: The SIM PIN must be entered on the Mobile Configuration page.
  • SIM PIN incorrect: The SIM PIN entered does not match the actual one for the SIM.
  • SIM not ready: No SIM inserted or other SIM problem.
  • Not registered: The modem did not register with a cellular network.
  • Dial failed: Error starting data connection.
  • Authentication failed: Incorrect login or password entered on the Mobile Configuration page.
  • Connection timeout: Connection did not complete.
  • Device reset error: The modem could not be reset.
  • Device open error: The modem is malfunctioning.
  • Device config error: The modem could not be configured.
  • PPP error: Internal system error.
Disconnect reason

This status appears after a previous connection ends. The possible reasons the previous connection ended are as follows:

  • User requested: Initiated by user action.
  • Network disconnect: Initiated by cellular network or carrier.
  • Carrier loss: Poor signal or disconnected by network.
  • Connection timer: Connection did not complete.
  • Receive idle timer: No data received for configured receive idle time.
  • Device monitoring error: Error while monitoring the modem status. May indicate a malfunctioning modem.
IP address Internet protocol address of the mobile data interface. You can contact the device at this IP address if permitted by the carrier.
DNS primary address

IP address of the primary Domain Name System (DNS) server assigned by the mobile carrier. This server resolves domain names to IP addresses.

See Default behavior regarding DNS for more information on how XBee Industrial Gateway uses the DNS primary and secondary address.

Receive idle time The amount of time since the cellular modem last received data.
Transmit idle time The amount of time since the cellular modem last transmitted data.
Connections The number of mobile data connection attempts since the XBee Industrial Gateway cellular device was started.
Connection errors The number of unsuccessful mobile data connection attempts since the XBee Industrial Gateway cellular device was started.
Carrier loss The number of times the connection was lost because of poor signal or being disconnected by the network.
LCP echo failed The number of failed Link Control Protocol (LCP) echo requests that were sent after a “quiet” interval to test the cellular link and/or keep it alive. Not used by XBee Industrial Gateway cellular products.
Idle timeout The number of connection resets that occurred because the idle timeout reached/exceeded the maximum allowed for transmitted and received data.
User disconnect The number of disconnects of the cellular connection performed by device users.
Monitoring errors Number of errors encountered while monitoring the cellular modem status. May indicate a malfunctioning modem.
Device resets Number of cellular modem resets caused by errors, failed connection attempts, or user requests.
Received bytes Number of bytes received by the cellular modem during the current data session.
Transmitted bytes Number of bytes transmitted by the cellular modem during the current data session.
Total received bytes Total number of bytes received by the modem since the XBee Industrial Gateway cellular device was started.
Total transmitted bytes Total number of bytes transmitted by the modem since the XBee Industrial Gateway cellular device was started.
