3. Telegram

Telegram is interesting because it lets you do a lot more than your typical texting app, and it's completely free with zero ads. All of your texts and calls are encrypted and you can send absolutely any file type you want (even large ones up to 1.5 GB).

This is totally unique to most messaging apps that just support image and video files. All your messages are synced across all the supported devices because your messages (and even files) are stored in the cloud. However, you can delete texts whenever you wish and even make secret chats that dissolve messages on a timer. Plus, if you have up to 5,000 friends, you can invite all of them into one single group message!
