Can you end a mobile broadband contract without paying loads?

davebspark asked:

I’ve got a mobile broadband contract with orange but their prices are way too high, I’ve had to get a land line installed and my broadband connection is quicker and cheaper and seeing as i no longer want to use the mobile connection I would like to end the contract, I have called orange and they say I have to pay a large percentage of the remainder of the contract or continue it for another twelve months, does anyone have any ideas on how I can end this without great expense any ideas would be most helpful, thanks.
