Unlike telegram that lets you run a single account on multiple device simultaneously, WhatsApp has always had that strict rule of one account (number) to a device at a time, which means you can't run your WhatsApp account on multiple device at a time.

There is actually an app out there called Clone WhatsWeb. With this app you can clone a single WhatsApp account into more than one SmartPhone at a time. The app actually does this without causing any interference with the main app.

1. You can clone your work account to your personal phone/tablet or vice versa.
