Because WhatsApp is an app that many of us use, I recommend that we use it for two things:

- to practice
- to find a partner to practice with

You only have to write in the post "WhatsApp Me" the next so that many people can add you:

- Your name
- Your mother tongue (native language)
- The languages your are learning
- Your number phone
- Your country (optional)

FIRST CHECK HOW YOU HAVE TO WRITE YOUR PHONE NUMBER FOR INTERNATIONAL CONTACTS, also you maybe have to add some contacts according to this official WhatsApp information:
