storing, in memory, first information related to the first plurality of RA procedures associated with the first PLMN having the first PLMN Identity;
registering with a second PLMN having a second PLMN identity different than the first PLMN identity after registering with the first PLMN and after performing the first plurality of RA procedures;
discarding the first information from the memory responsive to registering with the second PLMN;
performing a second plurality of RA procedures while registered with the second PLMN;
storing, in the memory, second information related to the second plurality of RA procedures associated with the second PLMN having the second PLMN Identity; and
