The good news is I've fixed it.

The password details given have to be in pap-secrets, not chap-secrets,
it seems.

I init first with ATZ then with AT+CGDCONT=,,"mobile.o2.co.uk" then dial
*99***1#, and it works without difficulty.

If I do happen to get a failed connection, though, the phone won't
respond to AT commands again until I unplug and reconnect it. If I close
the connection normally, it is fine.
