How can i get the internet on my mobile to work?

i have recently changed network and am now on Orange with the Dolphin pay as you go package but the internet on my mobile wont work.

When i try it just says ';connection failed.'; in the internet settings folder it only comes up with ';O2 prepay GPRS'; (my previous network) i think this may be the problem, what can i do?How can i get the internet on my mobile to work?
you will need to contact orange and download their internet settings.



this is taken from their website:

To activate GPRS or Photo Messaging on your account, please call 150 from your Orange phone if you are a Pay Monthly customer, or 451 if you are a Pay-as-you-go customer.How can i get the internet on my mobile to work?
Hi the easiest way of getting the settings is either go onto the orange website %26amp; download the settings from there or go into your local orange store %26amp; ask them to sort the settings out for you %26amp; then you should get 2 texts come through 1 of the texts will be for the internet %26amp; the other will be for the picture msg settings so that you can send %26amp; recieve picture msgs ! when you get the texts through it will will say install settings now just click on yes %26amp; the settings will automatically be installed in your phone ... hope this helps
Isn't there somewhere in the settings that you can manually search for all available networks instead of your mobile searching automatically?
