The verdict in three sentences
In 2G/EDGE areas, home to roughly 45 % of West Africa's rural population, web-redirect checkout fails for lack of stable data, with 25 to 40 % abandonment. USSD payment (#144# Orange Money, *165# MTN MoMo) works with no data and no installed app and confirms in 20 to 60 seconds. Offering USSD as a fallback is not a luxury: it is what saves the sale outside the big cities.
Web-redirect, USSD push and QR: when each wins
Each method has its arena. The mistake is forcing web-redirect everywhere.
| Method | Data needed | App needed | Confirmation | Ideal terrain |
|---|---|---|---|---|
| App-redirect | Yes (3G+) | Yes | 10-30 s | Urban, smartphone |
| USSD push | No | No | 20-60 s | Rural, 2G/EDGE |
| In-person QR | Merchant side | Yes | 5-15 s | Physical store |
| Web-redirect | Yes | No | 15-45 s | Urban, desktop |
On 2G, only USSD holds up. Web-redirect abandonment there climbs to 25-40 % because the operator page won't load or times out.
USSD codes and success rates by network
The codes and rates below are 2026 orders of magnitude; exact codes vary by country and operator.
| Operator | USSD code | Data | 2G success | 4G success |
|---|---|---|---|---|
| Orange Money | #144# | No | ~62 % | ~94 % |
| MTN MoMo | *165# | No | ~60 % | ~93 % |
| Moov Money | *155# | No | ~58 % | ~91 % |
| Wave (app) | via app | Yes | ~40 % | ~95 % |
| Free Money | #150# | No | ~57 % | ~90 % |
Wave, very strong in cities thanks to its app, drops on 2G because it depends on data. Orange/MTN/Moov USSD stays the backbone of rural fallback.

Mini case study
Aminata delivers farm produce from Kaolack to 2G villages. On 200 orders/month at 8,000 FCFA, her web-redirect checkout converts at 65 % = 130 sales = 1,040,000 FCFA. Adding a USSD fallback, the rate rises to 82 % = 164 sales = 1,312,000 FCFA. Net gain: +34 sales/month, i.e. +272,000 FCFA/month — with zero extra advertising, just by recovering baskets abandoned for lack of network.
FAQ
Does USSD really work without internet? Yes. USSD runs over the GSM signaling channel, available as soon as there is 2G coverage, even without data. That is why its success rate reaches ~62 % where web-redirect collapses.
How long does a USSD confirmation take? Between 20 and 60 seconds depending on operator and network load. Your system must wait for the confirmation webhook before validating the order, never the client display alone.
Do I need one USSD code per operator? Yes: #144# for Orange Money, *165# for MTN MoMo, *155# for Moov. A good integrator routes automatically based on the detected operator of the customer's number.
What share of customers is affected? About 45 % of the rural West African population lives outside stable 4G coverage. For a merchant delivering to regions, ignoring USSD means losing nearly one rural basket in three.
Can I combine QR, app and USSD? Yes, that is the ideal setup: QR in store, app-redirect in the city, USSD as rural fallback. The system chooses based on network context and channel.
