Kazakhstan implemented identification for SIM cards few years ago, just ID, no photo. Also recently it implemented identification for IMEI numbers as well. I'm not sure why, apparently they want to fight phone stealing, but I'm not very convinced.

When I bought a prepaid SIM card in Germany a few years ago they took a photocopy if my passport is not quite.
