NAWEC vs Jokko9

Monitor and manage your water and electricity usage - all from one app.

The Gambia is changing from 7-digit to 9-digit phone numbers. Every number saved in your phone needs the new operator prefix added — and if you have hundreds of contacts, doing that by hand is slow and easy to get wrong. Jokko9 does it for you. It scans your saved contacts, works out which operator each number belongs to, and shows you exactly what it will change before anything happens. You approve, and it updates them all at once. HOW IT WORKS • Africell numbers get the 87 prefix • QCell numbers get the 83 prefix • Comium numbers get the 86 prefix • Gamcel numbers stay 7 digits, as PURA specified • Anything unrecognised is flagged for you to check yourself COMPLETELY PRIVATE Jokko9 works entirely offline. There is no account, no sign-up, and no internet connection — your contacts never leave your phone. Nothing is uploaded, and nothing is tracked. YOU STAY IN CONTROL Review every change before it is applied, and keep a record of the original numbers.
