Hi, the problem of sim cards not being paged is only for certain sim cards. It’s always the same sim cards that have the problem so most probably it’s not because of paging occurring on different time slots (unless if they are configured to work only on different time slots than 0 which doesn’t seem logical). Also it doesn’t seem related to sim card manufacturing date since I face the same problem with some old and new sim cards.
