Yes, the user always accesses their home MMSC regardless of whether they are in their home network or roaming in a visited network. If the user is roaming in a visited network, a packet data roaming session is established to allow the mobile to access its home MMSC. This session is the same as any other packet data roaming session that would be established in order for a roamer to access an application server in their home network.
