NAWEC vs UpdateContacts

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

From 4 September 2026, every mobile number in The Gambia changes. A two-digit operator prefix goes in front of the seven digits you already know, and the old numbers stop connecting. If you have a few hundred contacts, fixing them by hand is a long evening. If you have a few thousand, it is not realistic at all. UpdateContacts does it in one pass. SCAN UpdateContacts reads the contacts on your phone and works out which numbers use the old format, and which operator each one belongs to. Numbers that are not changing — Gamtel landlines, short codes, USSD strings and international numbers — are left alone. PREVIEW You see every single edit before anything happens. Old number, new number, contact by contact. Nothing is saved until you confirm. UPDATE Every number is changed in one go. An encrypted backup is written first, and one tap puts everything back if you change your mind. FOR INDIVIDUALS AND INSTITUTIONS The number update is available for both individuals and institutions, public and private. A business, ministry or school with thousands of numbers in a shared address book runs exactly the same flow as one person with their own phone. The bulk update, the encrypted backup and the undo do not change with volume. FREE TO SCAN AND PREVIEW Scanning, previewing, the single-number converter and the migration information are free, and always will be. A one-time unlock adds bulk updating, encrypted backups, restore and undo. No subscription and no repeat charges. YOUR CONTACTS STAY ON YOUR PHONE The scan runs entirely on your device. Your address book is never uploaded — there is no server involved in scanning at all. UpdateContacts never asks for your phone number.
