In this paper we present two methods to improve the quantum teleportation processes for teleporting a coherent state via the pair coherent states. In our protocols, we use the measurement of the orthogonal quadrature components, and the photon number sum and phase difference. In the first protocol, we add a displacement of photon number at receiver and indicate measurement of probability in the second protocol. In the two methods mentioned above, our results show that the average fidelities approach to unit depending on the parameters involved.
