I have two questions about RCS.

First, the pricing model. Similar to SMS, RCS is a service provided by carrier. Many carriers include unlimited text messages in their phone plans, but not all carriers do that. And that's only for domestic messaging. When it comes to international communication, would carriers handle RCS like an instant messaging app or charge users per text message like SMS? That could be a huge number on the bill.

Second, the structure and server. Currently, most carriers have given up on making their own RCS infrastructure and let Google's Jibe run it. If iOS joins RCS, and RCS is implemented globally in the future, how would messages be transferred between different carriers, different cloud platforms, and different operating systems?
