Give 191 a call or use Live Chat to ascertain if your account is provisioned for mms.

Hi and Welcome to the eforum. 

Have you been successful in sending / receiving mms before ?

As you need a data connection for this service to work do you have Mobile Data turned on giving you at least a 3G connection.
