According to the Lumia 635 webpage that’s found at Microsoft Canada’s official website, the handset will be released by Rogers and Telus. There is now word on exactly when the new smartphone will go on sale, but we assume it will happen pretty soon - since the Lumia 630 (which is a Lumia 635 variant without LTE) was launched earlier this month in Europe.
Apart from featuring LTE connectivity, the Lumia 635 is identical to the 630. Thus, it comes with Windows Phone 8.1, a 4.5-inch IPS display with 480 x 854 pixels, 5MP rear camera, quad-core Snapdragon 400 processor clocked at 1.2GHz, and a 1,830 mAH battery. The handset offers 8GB of expandable internal memory, and only 512MB of RAM.
Unlocked, the Nokia Lumia 635 will cost less than $200 - which means that US and Canadian carriers can offer it for free on contract.
