The techies reckon it should be working and im on the correct plan etc
Spent an about 2 hours on the phone this afternoon

Managed to narrow the problem down to the command ATDT#777 - have a look at the modem log below
Ive tried to troubleshoot the connection in hyperterminal over the relevant com port and I can issue the modem with most AT command except the ATDT command always returns ERROR. Anyone know of or had this problem on the A920
