Graham, can you do some other tests for us?  Can you try other CIDs?

AT^NDISDUP=<cid>,1,"<apn>"

You noted the response for AT^NDISDUP=? included (1-20); what's the
result of:

AT+CGDCONT=?

Thanks!

Transcript follows, showing how the NDISDUP command connects, disconnects and updates PDP context #2.
It does not seem to like connecting with PDP context #0 though.  I have not seen a PDP context #0 in any 
other modem.

So it's interesting that the NDISDUP=? reported a range of (1-20) while
the CGDCONT=? reports a range of (0-31).  Can you try using
NDISDUP=21,1,"internet" for me?

In any case, I think we should probably pass the CID to NDISDUP, there
are other references to that, but we couldn't get a straight answer out
of Huawei about that.
