Last year, all SIM cards had to be registered with your passport ID. That was done.
Yesterday I got this text message from AIS.
"Urgent! Your passport (ID) photo is not clear or incomplete per NBTC's regulation, please bring your SIM + passport and contact AIS shop/Telewiz/AIS Buddy to register again within 12/12/2016 and get the free bonus call"
Only took them a year to check - but they did check.
