1. A method performed by a user equipment, (UE) having one or more subscriber identification modules (SIMs), the method comprising:
activating, via an activation code or an activation pattern, one or more SIMs for a UE;
as a result of activating, initiating a request to register the UE with a network, and receiving allowed Network Slice Selection Assistance Information (NSSAI);
associating received one or more single-NSSAI (S-NSSAI) indicated by the allowed NSSAI to one of the one or more SIMs in the UE according to a policy so that,
as a result of the activation of the one or more SIMs via the activation code or the activation pattern, all of the S-NSSAI indicated by the allowed NSSAI are associated to the activated one or more SIMs, or
as a result of the activation of the one or more SIMs via the activation code or the activation pattern, a subset of the S-NSSAI indicated by the allowed NSSAI are associated to the activated one or more SIMs according to the policy;
using one of the one or more S-NSSAI associated to one of the activated one or more SIMs to establish a Packet Data Unit (PDU) session; and
one SIM having multiple activation codes or activation patterns, and each activation code or activation pattern being associated with a corresponding subset of allowed NSSAI or all the allowed NSSAI.
