The Gambia has moved from 7-digit to 9-digit phone numbers. Jokko9 finds every number saved on your phone and updates it for you — free, offline, in seconds.

Until then, both formats work. After that, any 7-digit number still saved in your phone will simply fail to connect.
PURA, The Gambia's Public Utilities Regulatory Authority, has migrated the national numbering plan from 7 digits to 9. Every mobile number saved in every phone needs its operator prefix added. With hundreds of contacts that is slow and easy to get wrong — and one mistyped digit means someone you can no longer reach.
The new 9-digit format goes live nationwide.
Both old and new formats work until this date. Time to migrate.
Old 7-digit numbers stop working completely.
Jokko9 never changes a number without showing you first.
Reads every contact saved on your phone and checks which numbers still use the old format.
Works out whether each number is Africell, QCell, Comium or Gamcel from its first digit.
Applies PURA's official rules to build the correct 9-digit version of each number.
Accept it, edit it yourself, or skip it. Nothing is written until you approve.
Applies everything you approved at once, instead of editing contacts one at a time.
Every original number is stored on your device, so any change can be undone at any time.
The original number is never altered — an operator prefix is added in front of it.
| Operator | Numbers starting with | Rule | Example |
|---|---|---|---|
| Africell | 2, 4, 7 | Add 87 | 7123456 → 877123456 |
| QCell | 3, 5 | Add 83 | 3123456 → 833123456 |
| Comium | 6, 8 | Add 86 | 6123456 → 866123456 |
| Gamcel | 9 | No change | 9123456 → 9123456 |
Internationally, numbers are written as +220 followed by the 9-digit national number.
Jokko9 recognises the awkward cases and asks you, rather than assuming. These are surfaced for review, never rewritten silently.
The Android app ships without the internet permission at all. It is not that Jokko9 chooses not to send your data — it cannot.
Jokko9 was created by three final-year Computer Science students at the University of The Gambia, who saw the migration coming and built the tool the country needed. They presented the project to PURA, and the app implements the authority's published rules.
