Both channels sell the same classes of product. Neither is a different company. If you start on web and finish on USSD, you can still double-pay — the channels do not lock each other out.
Payments happen on Ewale (ewalepay.com or *714*22#), not on this blog.
What you need
- An honest look at your signal and battery.
- The same identifiers you would type on USSD.
The flow on *714*22#
- Pick one channel for this payment.
- Complete it. Wait for SMS.
- Only then consider the other channel for a different bill.
After you pay
Web is nicer for long smartcard numbers. USSD is nicer in a power cut with a keypad phone. The receipt is still SMS.
If something fails
- Started on both: Check history. You may already have two successes.
- Browser failed mid-pay: Check MoMo. Do not immediately dial USSD for the same bill until you know the web debit failed.
One channel, one debit, one SMS. Then stop.
