Hi there, does anyone have any knowledge of this? I am in Australia at the moment, Android handset and Amaysim is my provider (Optus based) and my wife is in NZ on Vodafone NZ. I have never been able to send an MMS to her in NZ successfully, but I can send successfully to anyone I have tried in Australia, including myself. She has sent me one successfull MMS message out of 6 attempts. She can send MMS to herself and anyone the tries in NZ. Could anyone please let me know if this is possible and the one success was a fluke, or is it just not going to work reliably. Unsuccessful attempts do incur a cost.
