The standout phone announced at Microsoft’s Build 2014 developer conference was undoubtably the Lumia 930. However, it might not prove as popular, sales-wise, as the new Lumia 630 and Lumia 635, which were also revealed during the opening keynote.
It’s an important phone for Microsoft, as the Lumia 630 is the first device to make use of Windows Phone 8.1′s dual-SIM card support. This will make it more interesting to buyers in developing markets, where dual-SIM phones are far more common. During the event, Nokia demonstrated the feature, showing each SIM will have its own Live Tile, and users can select which card they want to call or send messages using.
Wrapped up in a body shell which looks a lot like the new Nokia X range, the phone has a 4.5-inch, 480 x 854 pixel touchscreen, and is driven by the excellent 1.2GHz, quad-core Snapdragon 400 processor, with 512MB of RAM. There is a 5-megapixel camera on the rear, and a total of 8GB internal memory, plus a microSD card slot which will hold cards up to 128GB in size.
If you’re wondering what the difference between the Lumia 630 and Lumia 635 is, it’s about connectivity. Both the single SIM and dual-SIM Lumia 630 phones connect to 3G networks, while the 635 only comes with a single SIM option and 4G LTE connectivity.
Nokia wants to get the Lumia 630 on sale quickly, and is aiming for a May release. The 4G Lumia 635 will come later on in the year, and is expected around July.
