Nokia Chat Beta for Windows Phone will end on January 15, 2015. After this date, you will not be able to sign in, message your contacts, or access past conversations using Nokia Chat Beta for Windows Phone.
Thank you for your support and for contributing to the beta! We hope you’ve enjoyed using Nokia Chat Beta as much as we’ve had providing it to you.
We now warmly invite you to begin using Skype for Windows Phone. Make free Skype to Skype video and voice calls as well as send instant messages to friends and family around the world.
And again, we send our deepest thanks for being a part of the Nokia Chat Beta for Windows Phone.
