WhatsApp associates one number to one device and so even if you have a dual-SIM you can associate only one number to the official WhatsApp app. But if you use Lenovo K3 Note, you are in for a surprise. You can operate two numbers on WhatsApp on this Smartphone, thanks to the SecureZone feature that comes with the phone.
The SecureZone allows to run two accounts of any app to be run on the single device – one on the open zone and the other on the SecureZone, a setting that needs to be configured and set to run. If you add a WhatsApp on the secure zone, it allows you to associate another number here, in addition to the WhatsApp you might have in the open zone associated to another number.
Isn’t that cool? No rooting of the device, no third party untrusted app needed here. It’s simple and easy to setup. Do see our video on how to run two WhatsApp on the Lenovo K3 Note
