The best option on our list for sending messages and making international calls is WhatsApp, an entirely free messaging app for iOS and Android. You don't need to enter any names or other personal information to use the app, which offers secure end-to-end encryption for calls and messages.
Voice and video calls can have up to eight participants, and unlike the other messaging services on our list, WhatsApp allows free international calls. Other distinctive features include the capacity to voice-message record, share moments via Status (a feature akin to Snapchat and Instagram Stories), and share your location.
