Nokia - final steps of installation

After connecting my Nokia 6120 Classic, I successfully downloaded and installed BlueWhaleMail for this specific model.
Launching the application, Blue Whale tries to connect to the internet to ".....check for features specific to your phone.."
After several minutes a connection error is reported, as apparently APN is not correctly set up, but I'm not prompted to choose a different one, nor there is any way to specify proper one; I'm just asked to try again, but it doesn't work.

Any suggestion out there???

Hi mario_mail,

Sorry you've had a problem. We've done some work on APNs, and clearly have a bit more to do yet. May I ask some questions to help me understand and fix the problem? Please feel free to Private Message me the answers.

1. How did you download the application onto your phone? By clicking on a link in an SMS or by transferring the file via your PC/Apple? (If you clicked on the link in the SMS then we know there is a working APN on your phone.)

2. To understand what APN should be configured on your phone, could you tell me which country you are in, who your operator is, and whether you are a contract or pay-as-you-go/prepay user.

3. Finally, if you have the time to tell me which APNs (if any) are configured on your phone that would be helpful, but I appreciate it may take a bit of time, so you may not want to do this.

Many thanks for your help,
Richard
