Simultaneous events were held in Mumbai and Delhi to launch the Nokia X in India. The Nokia XL and Nokia X+ will be launched separately, within 60 days.
The Nokia X models will fit in between the existing Nokia Asha and Lumia lines and act as "feeder" devices to help encourage users to upgrade to Lumia phones.
Rather than Google's suite of apps which ship with every Android phone, Nokia will use its own Maps app alongside Microsoft's email, messaging and cloud storage services.
Operator tieups in over 60 countries will let users pay for apps and content through their phone bills. Nokia claims this significantly increases the likelihood of a user making a mobile payment.
The Nokia X screen is a 4-inch 480x800 pixel display with a capacitive touch sensor. The lockscreen shows notifications and you can respond to missed calls or messages by swiping.
