Those all seem to be included in the default keyboard, at least in WP8.1 Preview. Just tap the emoji button and go through the categories, or in 8.1 type a word like WiFi 📶 and the emoji will appear as a suggestion.
Here's some more: football 🏈, rocket 🚀, apple 🍎, heel 👡.
Edit: There are no 3rd party keyboards in Windows Phone.
