How can you change the main WhatsApp device in WhatsApp Business?
WhatsApp Business is specifically designed for small and medium-sized businesses that communicate with customers via WhatsApp. Changing the main device — i.e. the smartphone on which the WhatsApp Business app is installed — generally follows the same steps as with the regular WhatsApp version. However, companies should consider a few additional aspects:
1. Create backup (Android and iPhone)
Before you change the main unit, you should use a complete Chat backup create:
- Android: Settings > Chats > Chat backup > “Back up to Google Drive”
- iPhone: Settings > Chats > Chat backup > “Back up now” (iCloud)
Make sure that not only the chats, but also the media files be saved, especially if you regularly send PDFs, product images or invoices.
2. Verification on the new device
Install WhatsApp Business on the new device, enter the phone number you used so far, and verify it. The backup is automatically recognized as long as you're signed in with the same Google or iCloud account.
3. Check automations and labels
After recovery, you should ensure that:
- Chat labels (e.g. “New Customer”, “Open Request”) have been correctly adopted
- Automated messages, such as absence notes or quick replies, continue to work as required
- Links to tools or APIs (e.g. hellomateo, CRM systems) are reviewed
Tip: Plan the switch outside of business hours so as not to interrupt active calls.
Tips for changing the main device in WhatsApp
Changing devices doesn't have to be stressful — with a few preparations, the changeover can be made smoothly. Here are the most important tips at a glance:
1. Test backup regularly
Not only do you create a backup just before the change, but also regularly test whether it can actually be restored in an emergency. Many users are surprised when the backup is outdated or damaged.
2. Activate two-factor authentication
In WhatsApp, go to Settings > Account > Two-Step Verification to activate a PIN. This also protects your account if your device is lost or stolen.
3. Plan dual SIM or phone number change
If you also change your telephone number as part of the switch, use the function first “Change number” in WhatsApp settings before you activate the new device. This is how you keep all chats, groups, and settings.
4. Deregister old devices
Don't delete WhatsApp on the old device until the switch is complete. If in doubt, you can check again or check settings on the old device.
