Only voice chat for the app?

[Memeotis]

I haven't heard a mention of a text chat feature for the mobile app yet. They've made several remarks on how you'll be able to talk to your outfit while on your phone or pad. I really hope there's going to be a text chat, because when am I really going to use voice chat? At school, on the train? Hell no. The only time I can see myself using the app for voice chat is when I'm eating breakfast in the morning before I head to school - at any other time my desktop will probably be turned on. The place where voice chat is most useful is when you're actually playing.

Text chat, on the other hand, can be used at all times in the day. Is it a feature on the mobile app?
