Inbound Roamer Multimedia Messaging Systems ("IRMMS") are described that transfer Welcome Multimedia Messages ("MM") ("WMM") or Welcome Roaming Content ("WRC") to devices of inbound roamers. The IRMMS transfers MMs to inbound roamers without involving components of the corresponding home network (HPMN). The MMs include text messages, music clips, voice clips, video clips, photographs, and drawings, but are not so limited. Use of the IRMMS eliminates payment by a VPMN with which a subscriber is roaming to the subscriber's HPMN because components of the HPMN are not included in the transfer of the MMs. Thus, charges typically incurred by the VPMN for transmission of free WMM/WRC sent to the inbound roamer via the HPMN are avoided.
