USSD or app? How to reach customers without smartphones or data

Apps are great for customers with a smartphone, mobile data and storage space. Many of your customers may have none of those on the day they need you. USSD works on any phone, on any network, without data.

When USSD is the better choice

USSD wins when the task is short and the customer may not have data or a smartphone.

  • Paying a bill or buying airtime from a basic phone.
  • Checking a balance or a status.
  • Redeeming a voucher or registering for a programme.
  • Reaching rural customers and field agents with weak data coverage.

What USSD cannot do

A USSD screen holds about 182 characters, sessions time out if the customer is slow, and there are no images or rich forms. Long journeys, document uploads and browsing large catalogues belong in an app or on the web.

Design a menu customers finish

Every extra step loses people. Keep the journey short and the words plain.

  • Put the most common task first, as option 1.
  • Use words customers use, not internal product names.
  • Ask for one thing per screen.
  • Confirm amounts and names before taking payment.
  • End with a clear result and send an SMS receipt.

Use both, on the same rails

The best setups offer USSD for quick tasks and an app for everything else, both connected to the same payment and vending APIs. Customers move between them without losing their history.
