How to Move WhatsApp Chats to iPhone 18 When Your Number Changes
A number change and a phone change are two separate parts of a WhatsApp move. Before setting up WhatsApp on the new iPhone, keep the old phone, old SIM or number access, and chat history available. Complete the number-change step on the old phone first when WhatsApp asks you to use its Change Number feature, then follow the transfer method shown in the app.
Prepare before the move
- Update WhatsApp on the old phone and confirm that the old chats are visible.
- Make sure you can receive the verification code for the number you intend to use.
- Do not erase, trade in, or reset the old phone until the new iPhone shows the chats you need.
Keep setup stages separate
Complete any iPhone setup transfer first. Then install or open WhatsApp on the new iPhone and follow its current in-app transfer or restore instructions. Do not assume that a full-device backup is the same thing as a WhatsApp-specific chat transfer.
If the path is unclear
Stop before creating a fresh WhatsApp account on the new phone if that could change the state of the migration. Take screenshots of the in-app prompt and contact WhatsApp Support for the exact account and number-change scenario. A dedicated WhatsApp backup on a computer can also be useful when you need a separate copy of chats before changing devices.
If you want a separate computer-based WhatsApp transfer or backup workflow while changing numbers, Dr.Fone - WhatsApp Transfer provides a dedicated option for WhatsApp data.
