I know why. You need to become a tester in order to use Wii U Chat or other supported applications. In order to become a tester, you have to go to their website and donate around 10 - 20$ a month to Pretendo.

is there another Way to use Wii U chat?

Sorry, but donating to Pretendo is the only way to access Wii U Chat..
