Frequently asked questions
How long does PIN reset take?
Phone customer care: 5-15 minutes in business hours. Service centre visit: on the spot. The temporary PIN arrives by SMS — change it before your first transaction.
Can I reset via the app?
On some operators yes — the Mixx Super App and M-Pesa Tanzania app expose a 'Change PIN' flow that uses biometrics + the registered phone for authentication. A fully blocked PIN still requires customer-care contact.
