In this paper, we introduce a new state called superposition of photon-added pair coherent state. The two-mode sum squeezing property of this state is studied. It indicates that this state has two-mode sum squeezing. This state is an entangled state and the entanglement degree can be enhanced by adding photons to both modes. When using this state as an entangled resource for quantum teleportation, the results show that the quantum teleportation process is successful and the average fidelity of the process can be higher than the case where the pair coherent state is used if parameters are selected appropriately.
