4. Line activation: The MTN representative will enrol your number(s) on the CUG platform. The activation process generally takes between 24 and 48 hours.
5. Confirmation and usage: You will receive a confirmation SMS from MTN. Once activated, you can enjoy free calls within your group.
Self-activation or third-party authorised platforms
For individuals or small groups, using self-service (if available) or trusted platforms like Samic is often more practical than visiting an MTN office. The entire process can be done online or through USSD. Below is a step-by-step on how to use Samic for a convenient and flexible online MTN CUG subscription.
