> What carrier are you using?
In this case it is Telenor.
> Does carrier support your modem, imei?
I am not sure what you mean by "support" here, but we are using the
MC7304 with Telenor now and before.
> Does carrier require provisioning before imei can be on network?
No. As said in earlier mails, it works sometimes.

Well, sometimes and eventually, but not at present using the manual
procedure.
