I've deleted all profiles and bearers.
After power-cycling and enabling the modem I can see two predefined PDP contexts.

root at dev:~# mmcli -m 0 -e                    
successfully enabled the modem
root at dev:~# mmcli -m 0 --command=AT+CGDCONT?
response: '+CGDCONT: 1,"IPV4V6","","",0,0
+CGDCONT: 3,"IP","*.vodafone.de","",0,0'

Where * corresponds to the real name of the private APN associated with the SIM card.
I think that's the reason, why CID 3 must be used to successfully estabish the data session.
