Although we used to see dual-SIM phones being released by the major handset makers in the past, lately all such devices come from China. Now that may change with Samsung announcing the D880 DuoS, the slider phone that can simultaneously work with two SIM cards. This translates into automatic configuration of such services as WAP, MMS and E-mail for two carriers without requiring any additional actions from the user. In addition, DuoS' owners can set different ringtones for each of the SIM cards and know exactly which phone number they are respond to.
Finally, let's talk about specs. Aside from two SIM slots, the D880 DuoS also boasts 2.3" QVGA screen, 3MP camera with autofocus, FM radio, stereo Bluetooth (A2DP), high-capacity battery (1200 mAh), microSD expansion slot, as well as such preinstalled software as music player and business card reader.
