One thing I did find, is that 3 mobiles DNS servers were not fit for
purpose. I installed BIND as a local DNS proxy server.

I was on the one occasion I found a signal strong enough and of
sufficient quality to actually have an internet connection, able to send
and receive mail from icedove AFAICR with no other issues of configuration.

OTOH maybe I used a webmail service from my (normal) ISP. I don't recall.,

frankly the whole affair merely proved to me that where I needed mobile
internet - away from my usual places of work - it didn't actually work.

I returned the loaned dongle to its owner, who wryly observed 'didn't
work for you, either huh?' :-)

This mirrors my experience with an o2 device at a number of locations.

The Vodaphone one I've replaced it with has more success, although
nowhere near 100%.

Yes, that's a problem with several mobile networks. I don't know
particularly why, but the DNS machines tend to be vastly overloaded and it's
quicker to go direct. If you can't run your own server, Google Public DNS
and OpenDNS can be a lot quicker than the network's DNS.

I think it depends. In many of the places I use mobile broadband there is
an existing internet connection, but it's easier just to whip out the laptop
and press 'connect' rather than try to find the right person to tell me
the wifi key.

If you're trying to use it in rural Suffolk then you might be pushing it.
Rural areas can be a bit marginal, if you have any signal at all, so
resorting to tricks like hanging the dongle on a USB cable out the window
can be required.

You can also get signal boosters (basically an aerial and an inductive
coupler) to help in marginal areas. For my purposes Vodafone pay as you
go works very well.

The one time it worked, signal strength was fine. But as soon as it got
to 5pm, the signal degraded as everybody else took up bandwidth on the
mast I suppose.
