All 5 Thuraya handsets (except for the SO-2510) have a dual-mode feature that allows them to operate in the Thuraya satellite network and GSM terrestrial mobile networks. Thuraya has concluded roaming agreements with over 200 wireless (cellular) operators around the world, providing its customers the ability of using their Thuraya phones outside the satellite coverage. The dual-mode feature of the handset is similar to the Telit (GSM/Satellite) and Qualcomm (CDMA/Satellite) handsets on the Globalstar system. Roaming for outgoing calls is only available for subscribers. For pre-pay (scratchcard) users of Thuraya roaming is only available for receiving incoming calls.
The satellite-only SO-2510 was released in November 2006. It has a colour screen and is claimed to be the smallest and lightest satellite phone in the world and uses the VxWorks operating system. The SG-2520 was released in early 2007, this is a dual-mode handset that also connects to GSM/GPRS services and is based on Windows CE and made by Apsat in South Korea. The device is slightly bigger than the SO-2510 but it also has a camera, GPS and support for SD Cards. The operating system is a rather customised version of Windows CE and is not at all like Windows Mobile. It has support for running Java J2ME applications only. Currently only the second generation handsets are on sale
