The 502 Dual SIM and the 503 are the two Asha 50x phones put on sale by Nokia. The two add a transparent outer layer on the back, but are based on the Asha 501.

By bumping the camera to 5MP and adding a LED flash, the Nokia Asha 502 Dual-SIM improves the phone’s photography skills. Though, the video recording is still at the abysmal QVGA@15fps.

It comes only in dual-SIM, as the name suggests. Wi-Fi and WhatsApp are available but this model has only 2G connectivity. Asha 502 has slightly smaller battery.

In single and dual-SIM versions, the Nokia Asha 503 comes. While keeping the improved camera, it also brings back the 3.5G connectivity from the Asha 501.  To the original 1,200mAh capacity, the battery is back too.
