Exclamation [4.2.2][i9100]Issue with MMS and more (connectivity)..!

I can't receive MMS most of the time. Can't send often too. I'm guessing this is related to the modem included in rootbox. My operator use the "Orange" network (France). Please tell me if you have an idea, which modem should i install (link required)? I use i9100 GSM, rom 4.2.2 called rootbox; Another issue i have is both wifi & data icon while connected stays white instead turning blue. Connection's avalaible for all but google service, big issue.. Reboot doesn't help (both phone & modem). Any idea? Really hope to fix this, this is the best rom i could get so far so don't wanna change!
