Media reports from Nigeria say the weekend attack on an MTN server saw the company lose R28m (N700m) in just under two hours, after subscribers accessed up to 120GB of free data per individual. The operator is, however, reported to have sent a text message to customers saying: “Dear customers, our electronic and VTU recharge channels may be unavailable from 12-8 am on Sunday, 16 June. Another text was sent later: “Dear valid customers, your SIM will be temporarily barred within the next 24 hours due to the consistent use of unassigned data.” “As service providers, MNOs [mobile network operators] are obligated to ensure the security and privacy of customer data. Service outage does happen at various operators periodically for various reasons, therefore, inability to provide a service for a couple of hours is not an event that will necessarily sway customers’ decision whether to stay with or move away from an operator,” he says. However, he cautions that if customer personal data has been compromised it could sway some customers to move away.
