Quote:WhatsApp is believed to be working on a major update that would allow users to enable the same account (with the same phone number) on more than just one device.
 
At this point, if you activate one WhatsApp account associated to a specific phone number on one device, all the other instances of the service are automatically blocked. In other words, you can only use WhatsApp on one mobile device and on your PC with the dedicated apps or WhatsApp Web in the browser.
 
But this could all change very soon, according to a rumor posted by WABetaInfo, as WhatsApp could be working on a whole new system that would make it possible to enable and use the same account on more than just one device.
 
WhatsApp is currently developing dedicated apps for Windows 10 that would enable PC users to chat on the messaging service without an active connection to the PC. This means that a new WhatsApp session on the same phone number would be activated on the computer, so even if your phone no longer has an Internet connection, you should still be able to send and receive messages on the desktop.
