If you're a frequent traveller or you're forced to carry a business phone that doesn't allow you to make personal calls, you've probably already considered a dual SIM phone. Dual SIM mobile phones let you simultaneously use two SIM cards, meaning that you don't have to carry two hand sets around with you, and you don't run the risk of missing calls whilst switching SIM cards between one phone. Up until recently one of the problems with having a dual SIM mobile phone was that they were distinctly lacking in features. However, as smart phones become more and more common, more manufacturers are adding dual SIM features to existing technology. This is good news for consumers, because it means that there are now some top of the line dual SIM phones on the market. If you're looking for something high end that also happens to be a dual SIM phone, then check out some of these models...
The Samsung Galaxy S Duos
The Galaxy S Duos just looks like a slightly thicker version of the Galaxy S III. It's a four inch touch screen TFT display, so it's high resolution, bright, clear and sharp. It's got a 1 GHz processor and runs 768 MB of RAM, making it fast and responsive. It runs Android's 4.0 Ice Cream Sandwich operating system, but is upgradable to the 4.1 Jelly Bean system. The Duos has a great camera as well as a video camera, and 4 GB of internal memory that's upgradable to 32 GB using a micro SD card. It supports 3G for both SIM cards. The Duos is probably one of the best dual SIM phones that we've seen.
The HTC Desire V
This is HTC's first foray into the world of dual SIM phones, and it's a pretty good one. A four inch LCD touch screen is pretty bright and sharp. A 1 GHz processor plus 512 MB of RAM makes it as fast as we'd expect from a device in HTC's mid range Desire line. It runs Android's 4.0 Ice Cream Sandwich operating system, and has 4 GB of internal memory, plus a micro SD card slot to ramp that up to 32 GB. The camera has a built in 5 MP device with full LED flash, which is pretty nice. Unfortunately, whilst both SIM cards will support 2G, the Desire will let only the primary SIM card be on 3G.
The Sony Xperia Tipo Dual
The Xperia doesn't quite have the power of the other models, but it's a pretty nice device anyway. It's got a 3.2 inch TFT LCD touch screen, that's fully scratch resistant. That's a little small for a touch screen, but it's high resolution so it's nice and clear. It runs an 800 MHz processor and 512 MB of RAM, which is why it's not quite as powerful as our other picks. But, both SIM cards can run 3G, and the battery life is a stunning two days, which is incredible for a dual SIM phone. The 3.2 MP camera is pretty average though. The Xperia runs Android 4.0 Ice Cream Sandwich.
“ Dual Sim mobile phones are taking the world by storm” , says Phil Turner. More features are becoming available which makes this mobile phone system the way to go.
