In this paper we argue that the upcoming 6G mobile system should have a new subscriber identity module (SIM). The SIM application used today, the USIM, is functionally the same as the 3G SIM (which dates back to 1999). The SIM holds the subscriber security credentials and algorithms,and these are used during the authentication and key agreement (AKA) procedures. That makes the 4G EPS-AKA and the 5G-AKA protocols, in important ways, restricted by the USIM functionality. This situation should be rectified, and our proposal is for a new 6G-SIM application and a new 6G baseline AKA (6G-BAKA) protocol.
