The verdict in three sentences
Showing six wallets at checkout creates choice paralysis; showing the wrong one loses the sale. The fix: detect the operator from the phone prefix and default it, cutting visible options from 6 to 2 primary + "others". Adding official logos lifts trust by 5 to 10 %, and remembering the last used wallet speeds up repeat purchases.
Detect the operator from the prefix
In Uganda, as in most countries, the phone prefix identifies the operator. You use it to pre-select the right wallet.
| Prefix (Uganda, e.g.) | Detected operator | Default wallet offered |
|---|---|---|
| 077 / 078 / 076 | MTN | MTN MoMo |
| 070 / 075 / 074 | Airtel | Airtel Money |
| Other / unknown | — | Full list shown |
| International number | — | Card / Stripe |
As soon as the buyer types their number, the right wallet moves to the top. They no longer see a grid of six logos but one obvious choice + a discreet fallback.
Reduce options without cutting coverage
| UX element | Without optimization | With optimization | Effect (est. 2026) |
|---|---|---|---|
| Wallets shown upfront | 6 | 2 + "others" | −paralysis, +5 to +8 % |
| Official logos shown | No | Yes | +5 to +10 % trust |
| Last wallet remembered | No | Yes | +3 to +6 % repeat buys |
| Prefix-based default | No | Yes | +4 to +7 % |
| Fallback ordering | Random | By market share | +2 to +4 % |
Coverage stays complete: less-common wallets do not disappear, they move behind an "Other payment methods". No one is excluded, but 80 % of buyers immediately see the right button.

Mini case study
Namono, who runs an online shop in Kampala, showed 6 wallets upfront with a 71 % selector conversion on 2,000 checkouts/month, or 1,420 payments initiated. Switching to prefix detection (2 defaults + logos), selector conversion rose to 79 %, or 1,580 payments. Average basket UGX 35,000 → 160 payments × 35,000 = UGX 5,600,000/month more, just by simplifying the choice screen.
FAQ
Why not show every wallet? Because six options create choice paralysis and slow the decision. Two relevant wallets + an "others" fallback are enough for 80 % of buyers, without excluding anyone.
Is prefix detection reliable? Yes for major operators, provided you keep the prefix table updated (including portability). Always plan an "unknown" case that shows the full list.
Do official logos really change conversion? Yes, they lift trust by 5 to 10 %: the buyer recognizes their brand and feels on safe ground. Use official logos, never generic icons.
Should you remember the last wallet? Yes, for repeat purchases: re-offering the previous wallet gains 3 to 6 % conversion and removes a needless decision.
How do you order the "others" fallback? By descending local market share. The country's most-used wallet after the two defaults appears first in the secondary list.
