In short: You can replace the number connected to Mumble from Settings, and your customers, lists and past chats stay. Moving a number to another Meta business portfolio, or changing the legal business, is done in Meta Business Manager. Each change affects something different, so check the list below first.
Replace the connected number
Before you switch:
- Templates belong to the WhatsApp Business Account (WABA). Add the new number to the same WABA to keep them.
- Quality rating belongs to the number. A new number starts without history.
- Tell your customers about the new number with a template before you switch.
- In Mumble, go to Settings > Technical Profile.
- Under Connect a new WhatsApp Business account, click the link.
- Complete Meta’s connection screen with the new number. See Connecting a New WhatsApp Number to Mumble.
- The new number replaces the old one on the same Mumble account. New messages go out from it.
- When you no longer need the old number, delete it in WhatsApp Manager > Phone numbers.
The new number can’t already be connected to another Mumble account. On their phones, customers see it as a new chat.
Move the number to another business portfolio
Messaging limits belong to the portfolio, so the number takes on the limit of the portfolio it joins. See WhatsApp Business API Messaging Limits.
- Pause any Click-to-WhatsApp ads that use the number.
- In Meta Business Manager of the receiving portfolio, go to Settings > Business assets and request the WhatsApp Business Account.
- An admin of the current portfolio approves the request.
- Check in Mumble that the number still shows as connected. If not, reconnect it from Settings > Technical Profile.
Change the legal business
- In Meta Business Manager, go to Settings > Business info and update the details.
- Submit documents for Meta Business Verification. It usually takes a few business days.
- Request a display name change separately, in WhatsApp Manager.
Common questions
Will I lose my chat history in Mumble?
No. Customers, lists and past chats stay in Mumble after you replace the number.
Customers still write to the old number
Keep announcing the new number. You can put the old number back in the WhatsApp Business app with an away message that points to the new one.
Our messaging limit dropped
The number probably joined a newer portfolio with a lower limit. Check it in WhatsApp Manager.
Can I run two numbers at once?
Each Mumble account holds one number. A second number needs its own Mumble account.
