MTN Ghana Announces Six-Hour MoMo Shutdown for Critical System Upgrade on August 17

MTN Ghana has issued a public advisory to its millions of Mobile Money (MoMo) users about an upcoming six-hour service disruption scheduled for Sunday, August 17, 2025.

According to the telecommunications giant, all MoMo services will be unavailable from 12:00 am to 6:00 am to facilitate a critical system upgrade. The downtime will affect all aspects of the platform, including deposits, withdrawals, transfers, and merchant payments.

This temporary shutdown is significant for Ghana, where MTN MoMo is a dominant financial service, processing billions of cedis in transactions and driving financial inclusion nationwide.

Speaking to Citi FM, Charles Asamoah Assah, Chief Technology & Service Delivery Officer at Mobile Money Limited, explained:

“Please be informed of a planned system upgrade on 17th August 2025, from 12 midnight to 6 am. During this period, all Mobile Money services will be unavailable. This upgrade is to improve our services to you. We sincerely apologise for any inconvenience caused and thank you for your understanding.”

The upgrade aims to enhance service delivery, with improvements expected in transaction speed, fraud prevention, and readiness for new digital services.

MTN Ghana assured customers that operations will resume immediately after the maintenance window and that all funds will remain safe. The company is advising individuals and businesses to complete all urgent transactions before the scheduled outage to avoid disruptions.
