I use HO-MOBILE provider (Vodafone).

It was working before the upgrade, I saw there was an upgrade available and after that stopped working.

Current ISP version: 20082701

I also created a new profile but I think the problem is not here.

I don't see "Signal" informatio at all in the status page and this should be present despite the ISP configuration.

I suspect there is a problem gathering IMSI from the SIM -> problem the the last firmware -> need firmware fix

No possible a firmware downgrade, already tried.
