Soracom provides detailed cellular session history information in the User Console as well as via API. These details can be used to check the connection status and perform basic troubleshooting, such as to check the country and network a device is connected to, and the dates and times of connections or disconnections.

The radio type of a session is included in these details, and until now have been either GSM or 3G or LTE, indicating that a device was connecting via a 2G/3G network or a 4G network, respectively.

With this update, the radio type details will now show GSM and 3G networks separately, and will also show if devices are connected to an LTE-M or an NB-IoT network:

• GSM - When a device is connected to a 2G network
• 3G - When a device is connected to a 3G network
• LTE - When a device is connected to a 4G/LTE network
• LTE-M - When a device is connected to an LTE Cat-M1 network
• NB-IoT - When a device is connected to an NB-IoT network

Please note that the radio type details displayed in the User Console and API correspond to the radio type reported by the local network. In some cases, a local network may report a different radio type than what the device is actually using. For example, if a device is connected to an LTE-M network but the local network reports the connection as LTE, the radio type will appear in the User Console and API as LTE.
