Hi,
Look at your tariff to see if MMS is included in your bundle.
If not then expect to pay £0.25p per message.
If you contact 02 they will be able to look at your payg account and advise you regarding the sending and receiving of that service.
From your O2 mobile 4445 25p per call
From a landline 0844 809 022 25p / min
This link may help you to obtain the MMS settings for your phone if you don't have them already.
