MCC and MNC information added to SIM List CSV (Updated)

The description was corrected on July 31, 2023. The correction is described below.

When a Soracom IoT SIM connects to a cellular network, Soracom stores details about the connection, which is referred to as a "session." These session details include MCC (Mobile Country Code) and MNC (Mobile Network Code), which indicate the country and network that a SIM is connected to, and details for both the current session (if the SIM is online) and the previous session are stored as part of the SIM's properties.

With this update, the following items will be added to the SIM List CSV, a file which contains a complete list of all SIMs in your account along with their details, after the renewalFeeStatusSetTime column:

  • currentMCC
  • currentMNC
  • previousMCC
  • previousMNC

By adding these new items, you can quickly sort and filter SIMs in your account to check the countries and networks they are currently or were previously connected to, in order to better understand connection behavior or to help with SIM management and troubleshooting.

This update will be applied starting from August 9, 2023.

Please note that the MCC and MNC values will appear as 3 digit and 1-3 digit numbers, respectively, rather than as text names, as these names may change over time. You can use resources such as mcc-mnc.com or Wikipedia: Mobile country code (and its related Mobile network codes pages) to find the name of the country or network as required. If an MNC value appears as a 1-digit number, simply add a leading 0 (such as 5 → 05) to determine the correct MNC.

The SIM List CSV can be downloaded from the SIM Management screen of the User Console, as well as from the Soracom API using the Subscriber:exportSubscribers API endpoint.
