Dual SIM Dual Standby Mobile Phone Solutions--- (I) Infineon

There are 4 mobile phone platforms to support the dual SIM dual standby function, Spreadtrum, MTK, Mstar and Infineon.

The new platform supports touch screen, WQVGA display for improved mobile browsing capabilities, Bluetooth for file sharing and WLAN for internet access. In addition it provides high audio and video performance with its on-chip integrated FM radio and the computing power of the ARM11 core in the X-GOLD 213. Furthermore the XMM 2138 supports both standby and active Dual-SIM phones, implying that both SIM are available on the network to receive calls or messages. Powered by a single X-GOLD 213 baseband chip, the optimized protocol stack enables both SIMs to be available on the network simultaneously.
