Free disposal phone number site

I was wondering does anyone know of a good UK 'free disposal phone number' sites. As I need to create an online account and it wants a phone number. But I don’t have a phone so it is a problem, and don’t want the expense of getting a cheap phone to just get a load of spam on it? So any advice would be welcomed. As I have tried a few sites, but when I enter the number, I get this number has already been used???  

I find that 00000000000 or 07000000000 works as good as any when creating any profile.

Or, if you want to receive messages here

I have not used this service, so I am interested in how well it works. It might be worth setting up a specific email account to receive the calls, instead of giving your own email address to this site.

Just found this. I have not used it myself so I am interested in how good / bad it is.

Sorry @Caker, it seem on my pc the link isnt showing?

Back to the story, I was thinking of websites like this, where they can send you 'sms' back and not just a random number so you can get codes etc.
