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.
