1. An apparatus, comprising:
at least one processor, wherein the at least one processor is configured to cause a wireless device to:
communicate with a first cell of a first public land mobile network (PLMN);
measure a plurality of neighboring cells, including a second cell of the first PLMN and a third cell of a second PLMN, wherein the second cell of the first PLMN and the third cell of the second PLMN use a first frequency, wherein the second PLMN is not indicated as being equivalent to the first PLMN;
when in licensed spectrum, exclude cells on the first frequency, including the second cell and the third cell, from a reselection based on the second PLMN not being indicated as equivalent to the first PLMN and based on the second cell and the third cell using the first frequency;
otherwise, exclude the third cell from the reselection based on the second PLMN not being indicated as equivalent to the first PLMN; and
perform the reselection excluding at least the third cell.
