mtn setting for vodacom phone

[leelee]

Have a Vodafone Sharp GX15 which Im now using on MTN, but I cannot send mms' from that phone. Put the sim card in another phone mms works, but in Vodafone Sharp GX15, can only receive mms', not send.

Did *123*12# but says cannot send over the air settings, and did get MTN consultant to talk me through the settings required, but still no luck!
