RCS is carrier driven, just like SMS and MMS, which it is trying to replace. So far in the USA our carriers have not figured out who is going to maintain and pay for the cross-carrier databases required for cross-carrier implementation and most importantly encryption.Apple would be crazy to even think about allowing an RCS option until all of the cross-carrier issues are resolved here in the USA and the rest of the world. Google has already stopped back from being the host of its RCS like chat services, and is putting the onus back on the carriers where Voice, SMS, and MMS already reside. Samsung has also stepped back.
