The firm said that its free PocketSkype software allows users to make voice calls using a Wi-Fi enabled Microsoft Pocket PC-based handheld at wireless hotspots.
Users need PDAs running Pocket PC 2003 and a 400MHz processor.
"PocketSkype is a thin version of Skype, developed specifically for PDA devices, making Skype mobile with the same core features of regular Skype software," the firm said in a statement.
"This includes free Skype to Skype worldwide calling to any Skype user, the ability to participate in free Skype conference calling, instant messaging, access to the Global Decentralised Directory, online presence and contact lists."
Skype currently boasts about 10 million downloads worldwide.
