• Popular messaging apps: WhatsApp, WeChat, Line, KakaoTalk, Kik, Viber, Telegram

• Cost: Generally free to download and use. WhatsApp charges users $1 a year after the first year. Other services charge for add-on features.

• Advantages: Allows users to send text messages without incurring SMS charges; let users send messages or make calls across different phones, and connect with friends without having to know or use obscure user names.

• Disadvantages: Some don’t offer programs for PCs; many are popular only in particular countries; none of the programs interconnect.
