The Siemens SX45 is a PDA mobile phone released by Siemens in 2002. It was one of the first Pocket PCs with mobile phone functionality. Because of its size and the fact that phone calls could only be made using a headset, it was not really in the same marketing segment as current smartphones.

It was replaced by the Siemens SX56.
