My phone is missing whatsapp communication What can I do to bring  back my whatsapp number? I was using  my friend  phone  to communicate  with my whatsapp number  and I forget to change and now she still have my whatsapp number and she continue to receive message.
If your WhatsApp account is registered on a different device, while using your number, you can easily reclaim your account, as long as you can receive text messages on that phone number.

Download WhatsApp on your phone, register your account with your number, and it will automatically close the account on your friends phone.



On a side note, if you're looking to transfer all your messages from your friends phone to your phone, you can transfer the local backup from that phone, to yours.
