I have a well working (tested) application that sends MMS to applications or phones through MMSC (using EAIF).
During release tests i just notices that some phones (not account numbers)aren't retrieving the MMS,
example: i use my SIM with my HP phone, pefect! i use my SIM with QTEK perfect! with some nokia it works, but my SIM with 6600 it doesn't!
I am trying to find a pattern, do you have any idea what it could be? is it content-type related? content formats? other conf???
