On June 30, 2017, we will no longer support the following platforms:
These platforms don't offer the kind of capabilities we need to expand our app's features in the future. If you use one of these affected mobile devices, we recommend upgrading to a newer OS version, or to a newer Android running OS 2.3.3+, iPhone running iOS 7+, or Windows Phone 8+ so that you can continue using WhatsApp.
Once you have one of these devices, simply install WhatsApp and verify your phone number on the new device. Keep in mind that WhatsApp can only be activated with one phone number on one device at a time.
There is currently no option to transfer your chat history between platforms. However, we provide the option to send your chat history attached to an email. Learn how to export your chat history on: Android | iPhone | Windows Phone | Nokia S40 | BlackBerry | Nokia S60 | BlackBerry 10
