WhatsApp

Grandma: It’s grandma again. I was going to send some pictures to Mary via SMS, but Mary said that I should use something called WhatsApp. What is it?

Grandson: WhatsApp is a smartphone-based messaging service that works over the Internet. It costs a bit to download, but after that, it's free. With WhatsApp, you can send your friends text messages, pictures, audio and video recordings, and even your location. You can also create a group where all messages are shared with everyone in the group.

Grandma: So when I send pictures to Mary with WhatsApp, it's free and I can easily send the same pictures to everyone in the Senior Club.

Grandson: That's right.

Grandma: Splendid! Thank you very much.
