1. A method of operating a wireless device providing communication with a wireless network, the method comprising:
registering with a first Public Land Mobile Network, PLMN, having a first PLMN identity;
performing a first plurality of random access, RA, procedures while registered with the first PLMN;
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 after registering with the first PLMN and after performing the first plurality of RA procedures, the second PLMN having a second PLMN identity different than the first PLMN identity;
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;
receiving a Random Access Channel, RACH, report request from the second PLMN after storing the first information and after storing the second information;
transmitting an information message to the second PLMN responsive to receiving the RACH report request, wherein the information message includes a plurality of RACH reports corresponding to the second plurality of RA procedures associated with the second PLMN identity based on the second information and omits RACH reports corresponding to the first plurality of RA procedures associated with the first PLMN identity based on the first information.
