1. Go to the Friends tab.

2. Tap your friend's name to see his/her status:

   If it shows Online, it means your friend is using JusTalk now, you can start a video or voice call to chat.

   If it shows Last seen, it means your friend has logged in JusTalk, but is not using it now. You can try to give him/her a call.

   If it shows Offline, it means your friend has logged out or deleted his/her account. You'd better find another time to call.

You can also tap the main red button in the middle to check your friends' online status in real time.
