There is one caveat though, if you send an unintended message to a person and want to delete it, you won't be able to erase it just yet. Then, you will be able to communicate with messages even if the phone is off. Going forward, you will see 'BETA' in the top left corner just beside your profile image. Just open the WhatsApp Web on the browser and it will ask to scan the QR code on the phone and there, a message on the browser prompts you to accept the invitation to join the beta programme. Users need not have to dig deep in the settings at all. However, to enable this feature, users have to opt-in 'Beta' programme on the desktop version. This will enable users stay connected to all contacts on WhatsApp through the computer even if the phone is switched off. Now, WhatsApp has rolled out a new update to both Android and iOS versions that would allow users to open WhatsApp Web on desktop even if the mobile phone has no internet connection.

For the past several months, WhatsApp has been testing multi-device features and recently, it also opened beta testing to the public.
