MetroPCS ChatLINK
The MetroPCS ChatLINK will work like this: your friend with a PTT enabled phone calls you up and invites you to chat. The invite supplies directions for the non-PTT users, and lets them press any key on their wireless or wireline phone to send calls. So, the MetroPCS ChatLINK application is more of a luxury-type program, but it’s still cool none-the-less.
