M-Pesa How-Tos, USSD and Troubleshooting
Most M-Pesa tasks can be done by USSD as well as in the app, which matters when you have no data or a basic phone. The main code opens the menu for balance, statement, PIN and transfers, Hakikisha shows the recipient name before you confirm, and number portability lets you keep your number across networks. When M-Pesa is not working, the cause is usually a network event or a limit rather than your account.
