I tried to send mms (picture) to my Jolla and Honor 6, got similar message both times:
MMSC: 200_OK
BODY: {'Transaction-Id': '77986', 'Response-Text': 'Bad recipient address', 'MMS-Version': '1.0'. 'Message-Type': 'm-send-conf', 'Response-Status': 'Error-message-format-corrupt'}

Operator in all three phones is Saunalahti (Elisa) in Finland.
fMMS 1.3.6-1 (updated yesterday).
Any idea about what is going on?

And big thanks for continued support of mms on N900!
