What is Bill-and-Keep?
Bill-and-keep is the recommended billing approach for MMS traffic that involves multiple carriers. Using this approach, carriers retail bill their own customers for MMS messaging and keep the revenue but do not wholesale bill partners for the MMS service itself. Since MMS message origination and delivery is always between the user and their home MMSC, even in roaming scenarios, the MMSC server and message storage resources used are always those of the user’s home network. Note that in the case of roaming, wholesale billing may still occur for the underlying packet data bandwidth that is used to transport these messages in a visited network.
