How to Restore WhatsApp to iPhone 18 Without the Old Phone (Lost or Broken)

If the old phone is lost or will not turn on, skip direct phone-to-phone transfer attempts. The practical path is to restore only from a backup that was created before the phone became unavailable. Without an accessible backup or the source phone, there may be no safe way to recreate chat history that was never copied elsewhere.

Start with what you still control

Confirm the account phone number can still receive verification messages.
Check the cloud account you used on the previous phone for an existing WhatsApp backup.
Use the same phone number and the same cloud account when the restore flow asks for them.

Choose the right recovery path

For an iPhone backup, use the restore option offered during WhatsApp setup only when it identifies a backup you recognize. For an Android-source situation, do not assume a Google Drive backup can be restored directly into WhatsApp on an iPhone; cross-platform transfer and a same-platform backup restore are different workflows.

Protect the account

If the phone was lost, secure the number with the carrier and remove access from any devices or sessions you do not recognize. Avoid erase, reinstall, or reset steps on the new phone until you know whether they could remove the only copy currently available.

If you created a WhatsApp-specific computer backup before the old phone was lost or became unusable, Dr.Fone - WhatsApp Transfer provides a separate restore workflow for that saved WhatsApp data. It cannot recreate chats that were never backed up.
