Nokia is preparing to launch a Lumia 625 in the coming weeks with a 4.7-inch display and LTE support. Sources familiar with Nokia's plans have confirmed to The Verge that the handset will debut as one of the cheapest and biggest Lumias yet. Images of the Lumia 625, have been published on the official Chinese radio communication device regulator website. Having passed certification in that region, it's expected to debut soon priced at just CNY1999 ($325) in a variety of colors.

Although the 625 includes a 4.7-inch display, it will run at 800 x 480 (WVGA) resolution. It's a low-end Lumia, with a dual-core 1.2GHz S4 processor, 512MB of RAM, and a 5-megapixel camera. There's no word on US availability, but one particular variant of the Lumia 625 recently passed through the FCC with support for AT&T's GSM network.

Nokia's Lumia 625 is the next part of the company's strategy to push Windows Phone to even lower price points. The Nokia Lumia 520 is the most popular Windows Phone worldwide, according to data from Adduplex, and it has secured 13.3 percent share. Similarly the Lumia 620 has secured 9.6 percent, and the Lumia 710 has 9.6 percent. While Nokia is pushing Microsoft's mobile OS to the low-end, it faces increasing competition from competitors like Samsung, and its own low-end Asha line continues to sell well against Lumia Windows Phones.
