Welcome to the guest forums!
I think we need some more information in order to understand your question.
Which chat services are you referring to?
If you are referring to Google Chat/Talk/Hangouts, that's easy to confirm.
You will have to download the Google Hangouts app from the Play Store.
Once you download and install the app, open it and sign in using your gmail address.
At that point, it should be enable for chat.
If you were referring to another app, feel free to register for our forums so we can help!
