Google has lost its patience with carriers/networks. In a bold and dangerous move it has decided to force their hands and will roll out RCS messaging with or without them.
If you own an iPhone users, the biggest hurdle holding you back from switching to Android is iMessage. RCS messaging is the solution to this problem by bringing iMessage-like features to Android devices. But RCS will mean even iPhones might have to get this support, negating the need for iMessage even on an iPhone.
The problem so far has been that the various carriers around the world have been dragging their feet when it comes to rolling out RCS support. Google has been trying valiantly to push carriers to speed up the process, but things aren’t going much faster.
Now Google is throwing in the towel on getting the carriers to bring RCS to everyone. Google is just going to roll it out itself.
