You can view your Air SIM's Session Logs (connection history) by clicking the checkbox next to your Air SIM, then clicking the Details button, and clicking the Session details tab.
Here you will see a list of your device's connection history.
For each log entry, an Event type describes the type of connection event:
|Your device created a new 3G/LTE session, and is able to communicate with the network.
|Your device has updated its existing session (handover). This may be due to switching cellular radio towers, switching between 3G and LTE, or other factors related to signal strength or signal coverage.
|Your device's session was terminated, and is unable to communicate.
