Hi,

I try to find how i can fix the "provisioning failed" message.

Actually, I have always troubles with T-Mobile. I think I need to fix 
this provisioning issue. How can I do this ? I tried to see where this 
provisioning in the source code but I was quickly lost.

Bellow, you could see some troubles I have.

scenario:
  * enable modem power ;
  * enter pin code ;
  * set APN ;
  * and tried to enable GPRS.

------------------------------------------------------------------

First, there are no answer from modem about "AT+COPS=3,2" command.

And next, the "+CGEV: ME DETACH" disturb me. In the documentation of the 
SIMCOM module, I see :

"The mobile equipment has forced a Packet Domain detach. This implies 
that all active contexts have been deactivated. These are not reported 
separately."

I tried to re-attach with "Active" command but it fails :

------------------------------------------------------------------
# dbus-send --system --type=method_call --print-reply --dest=org.ofono 
/simcom_1/context1 org.ofono.ConnectionContext.SetProperty 
string:"Active" variant:boolean:true
Error org.ofono.Error.NotAttached: GPRS is not attached
------------------------------------------------------------------

In ConnectionManager, I see the "Attached" variable is "False".

Can you help me ?

Regards,
Anthony.
