How to change the phone number associated with my WhatsApp account on a different device - in detail?

Changing your phone number on WhatsApp while using it on a different device can be accomplished by following these detailed steps:

1. Backup Your Chat History: Before you begin, ensure that all your important data is backed up. You can use Google Drive (for Android) or iCloud (for iPhone) to back up your chat history. This step is crucial as changing the phone number will erase your chat history on the device where WhatsApp is currently active.
2. Unlink Device: If you are using WhatsApp on a different device temporarily, it's essential to unlink this device from your account before changing the phone number. Go to WhatsApp > Settings > Linked Devices and select the device you want to unlink. Confirm the action by following the prompts.

3. Change Your Phone Number:

   • Open WhatsApp on the device where your account is currently active.
   • Navigate to Settings > Account.
   • Tap on Change number.
   • Enter your old phone number in the top field and your new phone number in the bottom field, then tap Next.
   • Verify your new phone number by entering the 6-digit code sent via SMS.

4. Transfer Your Account: If you intend to use WhatsApp on a different device permanently, you need to transfer your account:

   • On your old device (where your account is currently active), open WhatsApp and go to Settings > Linked Devices.
   • Tap on Link a device and follow the instructions to link your new phone.
   • Once linked, uninstall WhatsApp from your old device.
   • On your new device, open WhatsApp and complete the setup process using the same phone number you used on your old device. Your chat history will be transferred during this process.

5. Restore Chat History: After changing the phone number and transferring your account, you can restore your chat history from the backup:

   • For Android: During the setup process on your new device, WhatsApp will prompt you to restore your chat history from Google Drive. Follow the prompts to complete the restoration.
   • For iPhone: After setting up WhatsApp on your new device, go to Settings > Chats > Chat Backup and tap on Restore Chat History.

By following these detailed steps, you can successfully change the phone number associated with your WhatsApp account while using it on a different device.
