View a device's recent data sessions

Tracking your account's overall usage can easily be done on the Dashboard's Usage page as instructed on this guide. However, if you want to get more in-depth information on a SIM's session by session usage you can do so by going to a specific Device's page and scrolling down on the Status tab until you get to the Recent data usage card.

Pressing the Export JSON button on the top right will open up a new tab with JSON information on the latest 100 sessions the SIM had. Pro tip: Mozilla's Firefox browser automatically formats and color codes JSON making it a breeze to read. 


The information you will get is as follows:

  • linkid - One of your SIM's identifiers that represents the profile on the SIM card.
  • record_id - The identifier for that specific session
  • session_begin - The session start's timestamp (UTC)
  • timestamp - The session end's timestamp (UTC)
  • bytes - The amount of data used in the session
  • imei - The IMEI identifier for the modem the SIM is in
  • imeisv - The IMEISV (IMEI + 2 final digits for software version) identifier for the modem the SIM is in
  • cellid - The identifier for the cell your device is operating in
  • lac - The location area code for the base transceiver station used
  • network_name - The name of the carrier the SIM was on during the session

This information is also available through our REST API using:


Please note that for your security Hologram only operates with session metadata. If you want to dive even deeper into your usage you'd need to use a device side network analyzer tool like tshark or bmon.
