If the EF.EHPLMN exists, it contains the "Equivalent Home PLMN List". The odd part of that list is that it is not just a list of additional PLMN identities, but if the first digits of the IMSI are *not* listed in EF.EHPLMN, then the MCC/MNC of the IMSI prefix is suddently no longer considered the home network, but the subscriber is roaming. See TS 23.122: "If the HPLMN code derived from the IMSI is not present in the EHPLMN list, then it shall be treated as a Visited PLMN for PLMN selection purposes."
