From a real plan: changing a phone number
Critical riskKeep your old number working until everything has moved
If the old one stops working too early, you may be stuck in slow account recovery for every account you haven't moved yet.
Included because you chose Until I cancel it for “How long will your old number keep working”.
Apple Account: add the new number as a trusted phone number
If the details on your Apple Account stop working, signing in on a new device or recovering the account can stall.
Included because you selected Apple Account for “Which of these accounts have your phone number”.
Google Account: update your recovery phone and 2-Step Verification phone
Outdated recovery details make it much harder to get back in if you're ever locked out.
Included because you selected Google Account for “Which of these accounts have your phone number”.
Or just describe it
“We’re moving from Google Workspace to Microsoft 365.” “I’m changing my number next week and I use an iPhone and WhatsApp.” We’ll pick the right plan and fill in what we can.
