ELS61 internet connection bug | Telit Cinterion IoT Developer Community

I was able to get IP address and connect to network using the following commands:

AT+COPS=0,0 // network registration

AT+CSQ // check signal

AT+CGDCONT=1,"IP","internet" // define APN

AT+CGATT=1 // attach 

AT^SWWAN=1,1 // successfully received IP

Then I managed to "break" Gemalto using two phones on which I ran speedtest at the same time. Module loses internet connection, while AT+CGATT?, AT+COPS?, AT+CREG? and AT^SWWAN? responses all indicate that the network connection is still established.

Which command to I use to figure out if I have an internet connection?
