What should I do if the phone I take WhatsApp orders on is lost or stolen?

Lock the SIM with your mobile provider, then put the same number on a new phone. Only one phone can use a number, so this switches the lost phone off. Restore chats from a backup if you have one.

• Step 1: call your mobile provider and lock the SIM.
• Step 2: verify the same number in WhatsApp on a new phone. This deactivates the account on the old phone.
• No new SIM yet: email WhatsApp with the words Lost/Stolen: Please deactivate my account and your full international number.
• Time limit: a deactivated account is kept for up to 30 days, then deleted if not activated.
• Chats: if you backed up before the loss, you may be able to restore them.
