As we previously told you, the Lumia 530 should be introduced as a Windows Phone 8.1 successor to the Lumia 525 and Lumia 520 models. Naturally, this makes it a low-end smartphone. The Vietnamese retailer seems to confirm some of the rumored features of the Lumia 530, including: dual SIM capabilities, a quad-core Snapdragon 200 processor, 5MP fixed focus rear camera, 512MB of RAM, and 4GB of expandable internal memory.
It’s still not clear when the Lumia 530 will be available, and neither for what price (though this will certainly be a low one). Anyhow, Microsoft will likely release the handset in lots of markets around the world, including in the US - where T-Mobile and MetroPCS are expected to sell it.
