WhatsApp is a deeply useful service for people worldwide. We’ve found that one of the only issues that app users face is that they cannot communicate with friends and family who haven’t downloaded the app yet. WhatsApp only allows users with an account to chat with others within the platform. To fully benefit from the host of positives this app provides, you’ll have to convince the people in your life to join the WhatsApp circle. Once you’ve convinced everyone to join, you’ll find there are very few problems with the app.
