It is the first device to run on the new Asha platform, which is designed to make the experience faster and more responsive.
The Asha platform helps developers to create, publish and make more money from apps made specifically for the new generation of devices.
According to Nokia MTN has said it will offer the Nokia Asha 501 and ease access to Facebook.
“We are excited to support this initiative with Facebook in Nigeria and Zambia and we are looking forward to expand it to other markets," says Pieter Verkade, group chief commercial officer at MTN.
The handset pushes the boundaries of affordable smartphone design with bold color, a high-quality build and an innovative user interface.
It is accessible in six colours and comes in two parts - a durable, removable casing and the scratch-resistant glass display, which features a three-inch, capacitive touchscreen and a single 'back' button.
"The new Nokia Asha 501 raises the bar for what is possible in affordable smartphone design and optimization," said Timo Toikkanen, executive vice president for mobile phones, at Nokia.
"The synergy between the physical design and the engine that is the new Asha platform has created a smartphone with both style and substance at a great price."
The Nokia Asha 501 is expected to start shipping in June 2013.
It is expected to be available through approximately 60 operators and distributors in more than 90 countries worldwide.
