Ericsson F3507g WWAN no way to power it off

Binary package hint: network-manager

Once the WWAN connection is established, I can disconnect from network, but cannot power the device off (WWAN diode is on). Even if I disable GSM Networking in network manager applet.
I could send manually command AT+CFUN=0 to power it off. But maybe there should be some other way. Like shortcut for toggling WLAN and Bluetooth connectivity in my thinkpad.
On Windows System in the pop-up activated by this shortcut (Fn+F5) I can also enable/disable WWAN radio.
