If a MM "profile" is a set of APN settings, to be set in the modem one-by-one with eg. CGDCONT, it is different. A modem "profile" is this (ie: a set of APN, including attach APN, data APN, administrative APN, IMS apn, ...), plus additional settings related to VoLTE (SIP/SDP format and datagrams), SMS handling (over IMS, SGs, CSFG), audio codecs. All these settings are applied at once, depending on the inserted SIM. I know that Thales changes the required settings, and have heard that Sierra selects a whole different image instead (like a different virtual modem). Not sure about the handling by other manufacturers.
