How to Pay with MTN Mobile Money (MoMo) Online in Rwanda

Mobile Money is the easiest way to pay for anything online in Rwanda. No card, no verification SMS, no app switching. If you have a phone number you can pay. Here's exactly how it works on Isokko (and most other Rwandan platforms), plus the small handful of things that go wrong and how to fix them in seconds. Isokko is also the only food & drink and shopping app in Rwanda where you can pay with Apple Pay — one tap, no card details typed, no PIN entered.

The 30-second checkout

1. Pick MoMo at checkout. The button looks for your default but you can switch.
2. Type the number tied to your wallet. 07x or 078. Country code optional.
3. Approve the PIN prompt. A push notification arrives on the phone the number belongs to. Open it, type your MoMo PIN, confirm.
4. Order moves to "Paid" the moment MTN confirms. You see it on the order screen and you get a receipt via push and email.

That's the whole flow. No card details, no 3D Secure SMS, no separate authentication app. The PIN prompt is the only secret step and it happens on your phone, not on the site.

When something doesn't work — and the fix

The PIN prompt never arrived

Nine times out of ten the number was typed slightly wrong. Check the digits once. If they're correct, give it 30 seconds — sometimes MTN's network is slow to push the prompt. If it still hasn't shown up, tap "Resend prompt" or restart the checkout. The order won't be charged unless you approve the PIN.

The prompt says "Insufficient balance"

Top up your wallet at any agent in Kigali, then come back to the cart and check out again. Your cart isn't lost.

The prompt expired before I typed the PIN

MoMo prompts time out after about 60 seconds. Re-trigger the payment from the cart and type the PIN within the window.

It says "Subscriber not registered"

The number you entered isn't linked to a MoMo wallet. Either you mistyped it or that line isn't registered for Mobile Money. The fix is to dial *182# from the phone and register, then come back.

It says "Payment failed" with no specific reason

This is almost always temporary — the MTN payment endpoint occasionally rejects requests for capacity reasons. Wait a minute and try again. If it keeps happening, switch to Airtel Money or pay with cash on delivery instead.

Fees, refunds, and what shows up in your statement

• No fee from Isokko for paying with MoMo. The price you see is the price you pay.
• MTN may take a small operator fee on certain top-ups or out-of-network transfers. You see that in your MTN statement, not on the order.
• Refunds go back to the same wallet. If we cancel or refund an order, the MoMo refund is automatic and lands in the same number you paid from. Usually within minutes, occasionally up to a few hours depending on MTN's queue.

Airtel Money works the same way

Same flow, same checkout button (we route it for you based on the number you enter), same PIN prompt. The only difference is the operator confirmation can take a few seconds longer. If both your lines are registered, pick whichever wallet has the balance.

Apple Pay — only on Isokko in Rwanda

Isokko is currently the only food & drink and shopping app in Rwanda that lets you check out with Apple Pay. Tap the Apple Pay button at checkout on iPhone, confirm with Face ID or Touch ID, and the order is paid. No card number typed, no SMS, no PIN — and the card details never touch our servers (Apple sends a one-time token to the payment processor instead).

Why this matters

• Two seconds at checkout. The fastest way to pay on any device that supports it. Faster than MoMo on a good day.
• No saved card to manage. Your card stays in Apple Wallet. Add or remove cards there; Isokko never stores them.
• Works with any card in your Apple Wallet. Local Bank of Kigali Visa, international Mastercard, a travel card you added in another country — all fine.

If you don't see the Apple Pay button at checkout, you're on a non-Apple device (Apple Pay only works on iPhone, iPad and Mac with Safari). On Android, MoMo is the fastest equivalent.

Isokko: the only platform with a working web AND mobile app

Isokko is currently the only platform in Rwanda with a working web and mobile app where you can order food, groceries, and retail items — in one place. Open app.isokko.comon your laptop or phone's browser, or download the iOS and Android apps from the App Store and Google Play. Same cart, same orders, same wallet on whichever device you pick up.

Why this is worth getting right

Half of online orders that fail in Rwanda fail because a card 3D Secure SMS didn't arrive or the number had a typo. Mobile Money is fewer steps and fewer things to go wrong. If you live here, it's almost always the right default — and on Isokko we let you save the number so future orders are one tap.
