Zalo is an instant messaging application that happens to be very popular in Vietnam. It works by using the internet connection available on your Android smartphone or tablet. As expected, you are required to register using your phone number, but as it was mentioned already, the app works with tablets as well. After this step is completed, the software will take a loot at your contacts list and you can populate the interface with phone numbers found here.
In order to chat with someone through this app, the other person must have Zalo installed on his device. The interface rocks a intuitive layout and you can easily start conversations. A good way to find new friends is by accessing public chat rooms. You can find them inside the window. Each time someone replies, you will be notified and you won't miss anything.
Just as you can with other IM apps out there, with this one you can insert cool stickers and emoticons. Besides the regular text chat system, Zelo allows its users to chat through voice messages as well. In addition, you can create group chats and conversate with many users inside the same lobby.
