I have a nice new acer aspire one with the on board 3G phone thingie. We have windows xp service pack 3 i believe. We also have a Vodaphone (ireland) SIM and this give me three services 1) SMS which works, 2) a broadband connection which I don't use and 3) a modem device which our client software can see but cannot use. The modem device is called a 'Globe Trotter MO40x - Modem Interface' I've tried testing the modem using hyperterminal but when I click the dial button the system comes back with a 'No Answer' Status after about one second. I tried manual dialing in a predial terminal window and got a 'NO CARRIER' response to my dialling command So the modem is not making the call. I dial the same number on my mobile and the remote system answers. Any clues as to what my problem is? vodaphone or globe trotter? TIA mike
