So, apart from all this and this, 3’s mobile broadband service has just taken a new low turn.
Since Saturday afternoon, that is almost 6 days, the mobile broadband service from 3 just hasn’t worked at all. I don’t mean a slow or flaky connection. I mean just no connection at all.
Conversations with friends and other 3 customers also make it clear that even regular GSM coverage is terrible not only in Aberdeen but also in London.
Anyway, you’ve been warned. Pick O2, they seem to have a much better network and service.

I’m on a 3 mobile dongle in Birmingham, and haven’t had any major problems. A couple of dropped connections every now and then, although that could be because my USB slots are a bit loose, but apart from that, nothing to report. Sorry to hear you’re having problems.
Just passing by. Btw, you website have great content!
I have never in all my days known such poor service or such appauling support.
