Telit HE910 modem --- unable be put on line by Connman

Hello,

I am working on Telit HE910 modem.

I am using ofono 1.11, and the commit is
6e3a6156b34c52bde253b097976d0ba9dd575879.

For the Telit modem, "AT+CFUN=4" is used to enable
the modem. According to "Telit He910 AT Commands
Reference Guide", "issuing AT+CFUN=4[,0] actually
causes the module to perform either a network
deregistration and a SIM deactivation."

After this command is sent out, an unsolicited indication
"\r\n#QSS: 0\r\n" is received by of ofono. This means that
the sim card cannot be detected by the modem. It turns out
that Connman will not put the modem on line.

if "AT+CFUN=5" was used, it worked fine.

My questions are:
1. Why is "AT+CFUN=4" used to enable the modem, instead of "AT+CFUN=1" 
or "AT+CFUN=5"?
2. If "AT+CFUN=4" is reasonable, are there any solutions to solve this 
problem?

Thanks!

Mingli
