Laws are everywhere to prevent this, because without ID, a terrorist can buy a SIM card and put it in his GSM-controlled IED. Not sure how strong it is being enforced though, the terrorist can just give a homeless guy a few bucks to buy a SIM card for him. IIRC when I bought a SIM card in an Asian country I went to visit, the seller just entered her ID number into the system.
