Getting WhatsApp to work for both networks on a dual-SIM phone I have been using WhatsApp for a very long time in a dual mobile HTC Desire U under a specific network. Now, I would like to use WhatsApp for the other network too. 

Is it possible to use watsapp for both networks under a single roof? I have tried suggestions many other sources, but I did not find any solution.
You can install one app per phone So you cannot use it for more than 1 network in the same phone(dual sim phone)

From Whatsapp FAQ


  Your WhatsApp account can only be verified with one number, on one
  device. If you have a dual SIM phone, please note that you still must
  choose one number to verify with WhatsApp. There is no option to have
  a WhatsApp account with two phone numbers. If you attempt to
  frequently switch your WhatsApp account between different devices, at
  a certain point, you may be blocked from re-verifying your account. So
  please do not repeatedly switch between different devices.
