About supported operating systems
We provide support for and recommend using the following devices:
- Android running OS 4.1 and newer

Once you have one of these devices, install WhatsApp and register your phone number. WhatsApp can only be activated with one phone number on one device at a time.
Furthermore, there's no option to transfer your chat history between platforms. However, we provide the option to export your chat history as an email attachment.
