Following the Communications and Information Ministry's regulation on mobile phone numbers, prepaid SIM card users are now required to register their numbers, starting from Oct. 31 to Feb. 28, 2018.
The program is supported by cellular service operators, which means you can register via SMS or the operators' websites.
