Precautions while using WhatsApp
Use your non phone channels
In the smartphone era, its worth remembering that not being accessible via a single phone number is not the restriction you might think. With Wi Fi, you can still access email, Twitter, Facebook, and free messaging apps like Skype, FaceTime, WhatsApp and Viber. That gives you plenty of ways to talk to others, and for others to get in touch with you in emergencies.
