Cant recieve picture messages on my samsung tocco?

I recently bought a samsung tocco through virgin media as i had a sim monthly contract with them and wanted to keep the contract. I recieved a picture message which i thought i would have been able to oepn however, it came up with a message asking me to go onto the internet and type in the code and stuff. So i went onto the samsung website and the virgin mobile website and downloaded the mms settings. I got sent the picture message again but still didnt work.

I would be very very greatful if someone could help me with this situation.

Thanks
