Choose the correct transfer path
- Check whether both phones use the same operating system or you are crossing between iPhone and Android; WhatsApp's supported methods differ.
- Confirm the phone number you will register on the new phone and that the old phone can still open WhatsApp.
- Check WhatsApp's current backup or chat-transfer instructions for that exact pair of devices before installing or registering on the new one.
Move chats and verify
- Use WhatsApp's own chat-transfer or supported restore process; an ordinary phone copy is not proof that chat history moved.
- Follow the on-screen QR or backup instructions without interrupting either phone.
- On the new phone, open several recent and older chats and confirm important media before retiring the old phone.
Protect the old copy
- Do not erase the old device or delete its WhatsApp data merely because the app appears on the new phone.
- If the transfer fails, use WhatsApp's official recovery instructions for the two platforms rather than repeatedly resetting the device.
- Carrier-line activation and WhatsApp chat transfer are separate checks; verify both before selling or wiping the old phone.
