Top-ups stopped
going to strangers

People left the top-up flow at the first screen, where they had to type a phone number. One wrong digit sent credit to a stranger.

01 · Problem

People quit at the phone number, and a wrong digit had no refund.

Data showed people quitting at the phone number screen, and support told us how bad it was: credit sent to the wrong number could not come back.

02 · What I did · done together

Pick the number from your contacts, with the reason explained first.

Let them pick the number from their contacts, and explained why before the app asked for permission. Typing stayed for anyone who preferred it.

The answer came from PM, tech, performance and support together.
