I've bought unlocked Ativ S and coudn't set up MMS for sending/receiving with APNs. What helped was factory resetting the phone, applying the GD2 update and factory resetting the phone again. It might have helped just to reset the phone.

Strange, it should work using the APN settings, search the Ativ S forum, quite a few did this.
