Two ways Meta allows a move
| Situation | What we do |
|---|---|
| The number is on Cloud API with another partner, and you want Best SMS Bulk to run it | Classic number migration. You admin the Meta business, the two-step PIN is off or you know it, and the previous provider releases the number for the short registration window. |
| Meta already allows more than one partner on the same WhatsApp Business Account | We can be added beside the current partner, then message traffic is routed to Best SMS Bulk. Nothing is deleted. |
| The number is only on the phone app | That is not this guide. Use app migration or coexistence. |
Send us a screenshot of the number inside WhatsApp Manager before anyone turns off two-step verification or removes a partner. The wrong click on a live WABA is harder to undo than a delayed move.
What you keep
- Approved message templates on that WhatsApp Business Account
- The green, yellow, or red quality rating
- The current messaging limit
- The display name, once it is already approved
- The phone number customers already message
Chat history inside the old provider’s inbox does not copy across automatically. Export anything you must keep from that platform before the cutover date. OneBox stores messages from the moment webhooks point here.
Prepare the cutover
- Confirm you are an admin of the Meta business that owns the WhatsApp account.
- Complete business verification if Meta still shows the portfolio as unverified. Some migrations wait on it.
- Follow turn off two-step verification, or have the six-digit PIN ready. Registration fails without it.
- Agree a time with the current provider so they stop holding the number. Overlap causes “number already registered.”
- We register the number on Best SMS Bulk and confirm inbound plus a template send before you close the old inbox.
Coexistence numbers
If the phone still uses the WhatsApp Business app through coexistence, leave that app account in place. Back up chats on the phone if you want a local copy, then migrate the API connection. Deleting the Business app account would drop the number off both the phone and the API.
FAQ
Will customers notice?
The number and display name stay the same. There can be a short gap while registration moves. Warn the team not to send campaigns during that window.
Do templates need to be reapproved?
Templates that already belong to the WhatsApp Business Account remain. A brand-new WABA would mean submitting templates again, which is why we migrate the existing account when we can.
Can Best SMS Bulk pull messages from my old provider?
No. Download reports or transcripts from them if you need an archive. New messages arrive in OneBox after the number points here.
