As of April 4th, President Muhammadu Buhari has authorized the implementation of the NIN-SIM Policy and instructed Telcos, to ban all outgoing calls on Non-Linked mobile phone lines.

In a joint statement released on Monday in Abuja, Dr. Ikechukwu Adinde, Director, Public Affairs, Nigerian Communications Commission, NCC, and Kayode Adegoke, Head, Corporate Communications, National Identity Management Commission, NIMC, said as much.

Following the Federal Government’s mandate about Link NIN, the country’s telecommunications companies have blocked nearly 73 million connections that have yet to be connected to a National Identification Number (NIN).

According to the government, 125 million lines have been connected as of yesterday.

According to data released by the Nigerian Communications Commission (NCC), as of January this year, the four GSM operators, MTN, Globacom, Airtel, and 9mobile, had 198 million active lines, which means that over 73 million lines were yet to be connected as more lines were activated between February and March.

Those who have yet to link their lines will no longer be allowed to make calls, but will still be able to receive calls, according to the directive, which went into force yesterday. On December 9, 2020, the government announced the required NIN-SIM linking exercise, with a December 31, 2020 deadline for all users to comply or be barred from the networks.

However, the deadline has been extended multiple times since then. The administration claimed another extension by ‘a few days’ after the last deadline expired on March 31, 2022, but it has now expired.

“From April 4th, 2022, outgoing calls for telephone lines that have not adhered with the NIN-SIM linking Policy will be forbidden,” the announcement added. Before the telcos can remove the ban on their lines, subscribers require link their SIMs to their NINs.
