Subscribers of MTN, the largest telecom provider in Nigeria, may soon face service disruption in the West African nation, according to a notice seen by some journalists and outlets. 

A rise in insecurity challenges in Nigeria is likely to disrupt MTN’s service, Reuters and others said, citing an alert from customer service reps. Throughout this year, Nigerians have had to battle kidnappings, clashes between farmers and herders, mass abductions of students and armed robberies.
