Hardware and Specifications
The Lumia 720 Dual SIM features the same great design as the Lumia 720, with the provision of two SIM card slots. Considering the bevy of budget devices in the market that feature dual-SIM technology, this is a smart move by Nokia. The Lumia 720 Dual SIM comes with Qualcomm's MSM8227 1 GHZ dual-core processor. The device runs on 512 MB RAM and 8 GB internal memory. There is also a micro-SD card slot to boost internal memory to 64 GB.
Screen and Design
The 4.3-inch screen on the Lumia 720 Dual SIM features a resolution of 800 x 480, and comes with ClearBlack technology. This allows you to see the screen even in very bright conditions. The screen is also coated with Corning's Gorilla Glass 2, which makes it immune to scratches. The design of the Lumia 720 Dual SIM is exquisite, and is one of the best mobiles to come out of Nokia. The device is not too big that it is unwieldy, nor is it too small to hinder usability. The slightly contoured polycarbonate body also fits very snugly in the hand.
Camera and Multimedia
Imaging is an area where the Lumia 720 Dual SIM excels in, thanks to the 6.1 megapixel camera that comes with a Carl Zeiss lens. The camera unit also comes with an LED flash and features autofocus. The 1/3.6 inch sensor takes great images and videos, and the Lumia 720 Dual SIM beats every other mobile in this category. At the front, there is a 1.3 MP shooter that can record 720p videos.
Software and Features
The device runs Microsoft's Windows Phone 8 OS, and will soon get the Amber software update from Nokia, which should include additional functionality. The user interface features elements like live tiles, which show information in real-time. The bold design language of the UI merges very well with the design of the device.
Connectivity and Battery
The Nokia Lumia 720 Dual SIM features 3G, dual-band Wi-Fi and Bluetooth 3.0. Being a dual-SIM device, the mobile can connect to two different GSM networks, although only one can be used at a time for calling. The device has a 2,000 mAh Li-Ion battery that gives a talk time of 23 hours on 2G and 13 hours on 3G.
