  We exhibit the intriguing phenomena of "Less is More" using a set of
multipartite entangled states. We consider the quantum communication protocols
for the {\em exact} teleportation, superdense coding, and quantum key
distribution. We find that sometimes {\em less} entanglement is {\em more}
useful. To understand this phenomena we obtain a condition that a resource
state must satisfy to communicate a $n$-qubit pure state with $m$ terms. We
find that the an appropriate partition of the resource state should have a
von-Neumann entropy of ${\rm log}_{2} m$. Furthermore, it is shown that some
states may be suitable for exact superdense coding, but not for exact
teleportation.
