We consider alternative models to quantum mechanics, that have been proposed in the recent years in order to explain the EPR correlations between two particles. These models allow in principle local hidden variables produced at the source, and some superluminal "hidden communication" (or "influences") to reproduce the non-local correlations. Moving to the case of three particles, we show that these alternative models lead to signaling when "hidden communication" alone is considered as the origin of the correlations.
