Quick answer
Yes. With WhatsApp Coexistence you keep using the WhatsApp Business app on your phone and connect the same number to an AI assistant through the official WhatsApp Business Platform. You link the number by scanning a QR code in the app; your contacts and up to six months of chat history come across. In SOVA, when you reply to a customer from your phone, the AI pauses for that customer and resumes on its own after 30 minutes without phone replies — so the customer never gets two answers.
Key takeaways
- You do not have to give up the WhatsApp Business app: Coexistence lets the phone app and an AI assistant share one number.
- Setup is a QR-code scan inside the WhatsApp Business app — no new number, no SIM change, and your customers keep messaging the number they already know.
- Your contacts and up to six months of chat history are synced when you connect, so the AI starts with context.
- In SOVA, replying from your phone pauses the AI for that one customer; it resumes after 30 minutes without phone replies.
- Some app features switch off under Coexistence (broadcast lists, disappearing messages, the app's catalog and greeting tools) — know the list before you connect.
The short answer: yes, your phone and the AI share one number
Until recently, moving a number onto the WhatsApp Business API meant losing the WhatsApp Business app on that number. For a shop owner whose whole business lives in that app — years of customer chats, the number printed on the shop sign — that was a deal-breaker, and it is still the first question people ask before automating.
Meta's answer is Coexistence. The same number stays active in the WhatsApp Business app on your phone and is also connected to the official Cloud API, which is what an AI assistant like SOVA uses to reply. Customers see no difference: they message the same number, in the same chat, and get answers either from you or from the assistant.
How to connect: a QR code, not a new number
In SOVA, you choose "Keep using WhatsApp on my phone" when you connect WhatsApp. The flow then asks you to open the WhatsApp Business app on your phone and scan a QR code to link the number. There is no new SIM, no number port and nothing for your customers to change.
- Use a number that is already on the WhatsApp Business app (not the personal WhatsApp app), updated to a recent version.
- Have a Meta Business portfolio ready — the connect flow creates or selects one for you.
- Keep your phone to hand during setup; you confirm the link from inside the app.
- Your existing contacts and up to six months of chat history are synced at connect time, so the assistant can see who your customers are. Meta only allows this sync in the first 24 hours after connecting, which is why SOVA requests it immediately.
What happens when you reply from your phone
The real fear is not losing the app — it is the AI and a human talking over each other. A customer asks for a discount, you answer from your phone, and a second later the bot answers too. That is exactly what makes a business look automated in the bad way.
SOVA receives a copy of every reply you send from the WhatsApp Business app. The moment you reply to a customer yourself, the AI pauses for that customer only. Every other conversation keeps running on autopilot. When you have been quiet in that chat for 30 minutes, the AI resumes on its own, so a customer who comes back later in the evening is still answered instantly.
If you want the AI off for a customer for longer — a complaint you are handling personally, a big wholesale negotiation — you can switch the AI off for that one conversation in the SOVA inbox and switch it back on when you are done. Our guide to human handover on WhatsApp covers when to take over and when to hand back.
What changes in the WhatsApp Business app under Coexistence
Coexistence is Meta's feature, and Meta switches off some app features on a connected number because the API cannot support them. Know these before you connect:
- Broadcast lists are disabled, and existing lists become read-only. Use approved broadcast messages through the API instead — see our WhatsApp broadcast messages guide.
- Disappearing messages, view-once messages and live location are turned off for one-to-one chats.
- The app's own catalog, greeting message, away message, quick replies and labels stop working. The AI assistant takes over those jobs — it greets, answers when you are away and shares products from your SOVA catalogue.
- Group chats are not synced to the API; they carry on in the app as before.
- WhatsApp for Windows and WhatsApp for WearOS cannot stay linked as companion devices. Other linked devices can be re-linked after setup.
- You must open the WhatsApp Business app at least once every 14 days to keep the connection active.
- Meta also lists its native catalog and order messages as unsupported for Coexistence numbers. If taking orders inside the chat is central to your business, ask us to check your number before you connect.
Costs and limits
Messages you send yourself from the WhatsApp Business app stay free, as they always were. Messages the AI sends go through the official Cloud API and follow Meta's standard API pricing — replies inside the 24-hour customer-service window are free, and templates outside it are charged per message. SOVA passes Meta's rates through at cost; see WhatsApp Business API pricing explained.
A Coexistence number is limited to 20 messages per second. For a shop, clinic or restaurant that is far more than enough; it only matters for very large broadcast campaigns.
Coexistence or API-only: which should you choose?
Choose Coexistence if the owner or staff still want to chat from the phone, if your number is well known to customers, or if you want the AI to start with your chat history. That covers most small businesses.
Choose an API-only connection if nobody needs the phone app, if you rely on broadcast campaigns at scale, or if in-chat ordering is your main use. For the full comparison, read WhatsApp Business app vs API vs AI assistant.
Frequently asked questions
Can I use the WhatsApp Business app and the WhatsApp API on the same number?
Yes. Meta's Coexistence feature lets one number stay active in the WhatsApp Business app on your phone and on the Cloud API at the same time. You link it by scanning a QR code in the app.
Will the AI reply at the same time as me?
No. In SOVA, when you reply to a customer from your phone, the AI pauses for that customer and resumes automatically after 30 minutes without phone replies. You can also switch the AI off for a customer in the inbox for as long as you like.
Will I lose my old chats and contacts?
No. Your chats stay in the app, and SOVA syncs your contacts and up to six months of chat history when you connect, so the assistant starts with context.
Do I need a new phone number?
No. You keep the number your customers already know. Coexistence works with a number that is already on the WhatsApp Business app.
Does it work with personal WhatsApp?
No. Coexistence is only for numbers on the WhatsApp Business app. If you use personal WhatsApp for your business, move the number to the free WhatsApp Business app first.
What stops working in the app after I connect?
Broadcast lists, disappearing and view-once messages, live location, and the app's catalog, greeting, away message, quick replies and labels. Group chats keep working in the app but are not synced. You must also open the app at least once every 14 days.
