The Mobile World Congress, a four day event for technology fans and professionals, will feature an presentation by Nokia and their reason for the event might have been leaked.

The Nokia Lumia 520 and Lumia 720 have been rumored to make their debut during the MWC in Barcelona. While the Congress takes place from Feb. 25 to 28, Nokia is preparing an event on the first day.

According to a report, the Lumia 520 and Lumia 720 have been given nicknames, Fame and Zeal, respectively, and a few of the specifications were leaked.

Although not confirmed by Nokia, the Lumia 520, or Fame, will have a screen size of four-inches with Super Sensitive display, 8GB internal storage with 512MB of RAM, 1GHz dual-core processor, microSD card slot, and a five-megapixel rear-facing camera.
