Guest mark.lucas Posted December 19, 2006 Report Share Posted December 19, 2006 Hi I've had my Universal acting as a modem before successfully on T-Mobile UK - even got 340kbps downloads! However, after a rebuild of the laptop and the phone system, I can get the phone to act as a modem, but when I make a call to *99# the connection comes up , there's a flurry of send/receive data and then the connection goes down and the laptop reports a 720 error code = PPP config incompatibility - all the PPP options are selected WRT compression etc. I've also tried it with the AT startup string of AT+CGDCONT=1,"IP","general.t-mobile.uk","" but this makes no difference. The phone can connect to the inter net normally OK an picks up email. Azzurri my service provider don't have a clue so has anyone had this problem before and if so how did you fix it? Thanks for any input in advance. Link to comment Share on other sites More sharing options...
