Sony Xperia T will not send MMS

[Harrison Seal]

Hi, I recently got my Sony Xperia T on contract with 3. No matter what size picture I try and attach to a message, my phone will say 'could not send' after queuing the message for some time. I've tried cropping images but that has not helped, there just seems to be no way I can send pictures via text message. Can anybody help?

Thanks.

It might be a matter of how good your data speeds are. If they are bad, a picture will not send.
