Hi Ron.
>> There is NO SiMS button (white envelope) to be found on the downloaded app.
Of course: Left pane
Active Connections
| Stop | –> Button with white envelope.
Activations is only possible, if the connection to the authorization server is established.
Lower left corner indicator: green. This may take some time.
Enable “service” in the main menu –> Connections, may speed up the connect.
Greetings
