Dual Card Views

General Goods

A dual SIM mobile phone is one which holds two SIM cards. Initially, dual-SIM adapters were made available to use in regular mobile phones to allow them to contain two SIMs, and to switch from one to the other as required. This combination is called a standby dual-SIM phone. More recently, some phones have been produced that can natively work with two SIMs, both of which may be active at the same time. These are active dual-SIM phones. There are also some Chinese triple-SIM phones.[1] Akai Trio is the first phone with triple GSM SIM slots [2]

Dual-SIM operation allows the use of two services without the need to carry two phones at the same time. For example, the same handset can be used for business and private use with separate numbers and bills; or for travel, with an additional SIM for the country visited. Using multiple SIM cards allows the user to take advantage of different pricing plans for calls and text messages to certain destinations as well as mobile data usage.

Philips has made models Xenium 9@9w and 699 with this capability belonging to the restart to change active-line generation. Samsung also released the D880 DuoS in November 2007, a slider which can hold two SIM cards with simultaneous standby and the D780 which came much later both have limited function on the 2nd sim card, and there is a Windows Mobile based dual-sim phone too, called E-TEN glofiish DX900 (released in November 2008, been renamed to Acer Tempo DX900 in January 2009, after Acer bought E-TEN).

So happy together Looking to double your desktop's visual real estate? The Matrox G450 ($145), with its two 15-pin analog outputs and its converter cable with S-Video and composite-video jacks, lets you hook up two analog monitors (CRT or analog flat panel) or a single analog monitor and a TV. You can set independent refresh rates and resolutions up to 2,048 by 1,536 at 85Hz on the primary display and up to 1,600 by 1200 at 85Hz on the second. That's a lower maximum resolution on the second display than that offered by ATI's Radeon VE or Asus's AGP-V7100, but the G450 is the only card of the three that supports independent monitor settings under Windows 2000. The G450's MultiDesk software lets users define multiple virtual desktops (so you can run different apps on each monitor), and its eDualHead driver wraps Web pages across monitors and performs other Web-centric tricks.
