Sorry that I didn't make it very clear.

What I meant was that I have the SMS/MMS plan that I pay extra for already.
It allows me 200 SMS/MMS per month.

My concern is whether or not fMMS uses internet to send the pictures, or does it send them through MMS service of my cell provider? If it's the first, then I'll be getting charges for every kb sent. But if it's the second, then I'm not worried.

Thank you.
