Nokia, the world’s biggest cell phone manufacturer, revealed three new handset models today. The new models were designed to compete in the very active market of mid-priced phones. This market is highly competitive.

Nokia will start shipping the new models in the third-quarter of this year. The new mid-priced phones include the Nokia 6600 Fold, the Nokia 6600 Slide and the Nokia 3600 Slide. These models will sell for between 175 euros ($273) and 275 euros, excluding taxes and subsidies.

Nokia controls around 39% of the world’s mobile phone market. The company has recently made great sales progress in emerging markets with sales of its low-priced phones.
