Peru's telecoms regulator Osiptel said that operators will block 1.27mn cell phones with invalid IMEI numbers by January 8.
The move is in keeping with decree 1338, which created a national database of legitimate phones (Renteseg), with the aim of combatting the trafficking of stolen phones or the use of devices for illicit purposes. The measure was announced in September.
The watchdog said that operators will block devices with invalid IMEIs but won't suspend the mobile line nor require users to hand the phone to authorities.
Osiptel has supplied to the operators a list of phones with invalid IMEIs that showed activity between December 15, 2018 and January 5, 2019.
Many countries in Latin America, including Peru, have joined the GSMA's We Care campaign, which provides a global database of stolen phones and obliges mobile phone users to register their IMEI numbers.
An IMEI is a 15- or 17-digit code that uniquely identifies mobile phones and can enable a network to block a misplaced or stolen phone from making calls.
