Comment 14 for bug 603830

Hi,

the past Weeks, I tried to find the reason for this Bug together with Dan Williams, one of the NM Developers.
This isn't a NM Problem. It's the Modem Manager. Finally he told me the following, which I will share with you.

Ok, we've seen this before once or twice; with the Huawei E1552 and
there's a bug on gnome.org for it. We're not quite sure what's causing
it, but the Huawei firmware does not appear to be standards compliant
for the AT+COPS command. It may work if you wait for the modem to
auto-register with the network before starting the connection in NM.
But for now I guess we'll need to work around the problem where the
modem just goes idle when we tell it to start looking for providers :(

So there is actually no working solution except to use the Sakis3G Script, which works quite good.
