The MyMTN App runs on smartphones and needs internet. It offers more features than USSD. You can buy data, check your account, view offers, and contact support. It also shows services in a clear and organised way.

USSD works best for quick tasks and no internet access. Meanwhile, the MyMTN App works best for users who want more features and full account control.
