Mobile operators are communicating to their OEMs that support for RCSe/Joyn is now a key criterion for their devices to be included in the operators’ portfolios, though it is not yet mandatory. Telefonica has said that if a device does not support RCS/Joyn, it will not be dropped from their handset portfolio. But Vodafone is taking a tougher stance, saying that devices that do not support RCS/Joyn will find it tough to get into the operator’s handset portfolio.
