   “Despite the ongoing health crisis, the Nigeria Communications Commission (NCC) has ordered phone operators in the country to block SIM cards not linked to a national identity number (NIN), used to bundle together biometric records such as fingerprints and headshots. […] Even when people manage to get a NIN, they must then integrate it with their SIM card by texting their service provider a code, a process that users say is sometimes glitchy.”
