Nokia Chat beta, in case you didn’t know, is a Yahoo powered messaging service. It has now gone live for all Nokia devices including Lumia Windows Phones, Asha and other Series 40 feature phones and Symbian handsets. If you have been waiting, it is now live.
It seems odd, but the cross platform Nokia Chat has already been available for a while in some countries, but in others it has been missing. We aren’t sure why. The service aims to unite Nokia’s own chat messaging with Yahoo’s messenger and adds push notifications and live tile updates for Windows Phones.
You can also use it to share your location if you want to.
