Samsung joins Google in RCS shaming Apple
(www.theverge.com)
This is a most excellent place for technology news and articles.
My understanding with RCS is that similar to SMS it uses the infrastructure of your phone carrier. First question: Do all carriers support this? Second question: Is there anything that prevents carriers from eventually monetizing this? At least with some sort of roaming trap when you are abroad...
Most carriers support it. When they don't, the protocol can use a bridge. Google hosts a bridge. I guess you could also use the bridge if the carrier is trying to charge for it.
