Unable to use Dialup in WM5!

[Guest plsl]

I am trying to access internet from my Qtek 8310 smartphone.

Now i want to access internet from a dialup connection.

So as per User Manual, i go into:

start > settings > connection > dialup.

then add a account, set it to connect to internet, enter the phone #, username & password and left domain blank.

Once done i go to back to connection, press menu and go in advanced. i then set the internet connection to my newly added account.

Then i go to internet explorer, set connection to Internet then i and click on a default favorite. i notice that the signal bar change, it now has two arrow --> <-- one over the other (which is normal as its the data connection icon). But then the signal bar goes back to normal and IE says Error unable to place a call.

Im i doing something wrong ? Is my Service Operator not allowing me to use my cellphone to connect to internet using a dialup connection ? Did anyone was able to connect using a dialup connection ?
