You get correlations - you can "understand what you read" once you have the measurements from both entangled particles, so you need another channel of communication (with the associated delays) to get that information.

One side doing their interaction may cause a "spooky action at a distance" (according to some QM interpretations), but if you have only one side of readings and don't know what the other party measured in their interactions, you can't tell anything about what "the other side" did, so it does not help communication at all because you still need to transmit as many bits in a non-quantum way until you can do anything.
