Only 97%? I'd put it at more like 99% plus. (Many regulars here don't even think about it, but the entire list of people who have ever been here isn't 0.1% of all cellphone users.

There's going to be a lot more to it than that - RCS is in its infancy. We'll be getting direct WiFi texting, no carrier needed (which means some way of texting from a PC directly to someone's phone), unlimited attachment sizes (you want to "text" a 4GB movie to someone? go ahead.) and almost anything the industry can think of.
Texting (SMS) derives from the old POCSAG (Post Office Code Standardisation Advisory Group) protocol and was originally limited to 140 octets (160 ASCII characters or 80 Unicode characters). That was expanded to multi-message texting, so we can send almost unlimited length texts. But it's a hodge-podge of a piece of this, a piece of that. and Android users were getting annoyed that iPhone users had iMessage, which is much better than SMS/MMS (MMS is used for files - pictures, long texts if you tell he app to not break long texts, etc.) But iMessage is a proprietary protocol, and Apple won't allow anyone else to use it.
So now we have an open industry standard, RCS, that can easily be expanded as needed. (Sending pictures from one carrier to another is only about 10-15 years old [I forget when they got that straightened out, but I lost a lot of customers who wanted to be able to exchange pictures with people on Verizon], so it's going to take a while until RCS matures a bit.)
But one fine day ...
