MTN subscribers are having difficulty recharging their lines through mobile banking applications and the Unstructured Supplementary Service Data (USSD) channel.
Customers of the telecommunications operator took to social media on Friday to lament.
In a message sent to its customers, MTN asked users to recharge their lines through physical cards.
“Dear Customer, our bank recharge channels are currently unavailable. Kindly recharge using physical cards. We apologise for the inconvenience. Thank you,” the message reads.
Meanwhile, a message posted on the MTN Nigeria Support handle on Twitter states that the development is a “technical glitch” that is being worked on.
