The Nigerian Communications Commission has blocked 10.7 million mobile telephone lines in the last one week (since August 11) for improper registration.
It said on Tuesday that at the completion of a “strict monitoring of mobile operators in the country,” it was likely to block 28.61 million more lines found to be defective, which would bring the total number of deactivated lines to 38.78 million.
The ongoing deactivation of preregistered Subscribers Identification Modules cards on the network of mobile operators in the country led to the blockage of the telephone lines.
Speaking in Lagos, the NCC said the lines were barred due to improper registration details including poor fingerprints; lack of facial information and other biometric challenges.

Including my 2 etisalat lines

its ridiculous that no notice was sent out to affected customers before barring their lines.
