Quick message
I had similar problems with my operator (Orange UK). All settings looked correct but fMMS did not work. Then I took the SIM card out and moved it to my old phone and MMS did not work there either. So I guess the problem was with my operstor but, since I have never needed MMS in my life, I did not investigate further and happily got rid of fMMS - which I installed in the first place only out of curiosity anyway.
