This happens to me as well. Every Time I send an MMS pic message I get symbols from 919-594-0004 or 919-594-0001 and 0002. It is very annoying~  I called my service provider and they told me that they were not aware of this and haven't heard of it.  I have e-maild crunchsms and it appears they are a company from Australia.  In any case I will keep you informed of what I recieve back, in the meantime feel free to e-mail them as well [email protected]
