Microsoft India on Saturday announced a ‘Smart Exchange offer’ for its existing Asha consumers to upgrade to the newly launched Lumia 435 Dual SIM smartphone. The exchange offer is valid from March 7 till April 15 or till stocks last, and can be availed from authorised retail stores across the country.

To remind you, Microsoft had launched the Lumia 435 Dual SIM last month in India. The device also has a single SIM variant which comes with identical specifications except the additional SIM card slot; though it is not expected to launch in India.

It features a 4-inch WVGA (480×800 pixels) LCD display and is powered by a 1.2GHz dual-core Qualcomm Snapdragon 200 processor coupled with 1GB of RAM. The 8GB of built-in storage is further expandable storage support via microSD card (up to 128GB). The Lumia 435 Dual SIM sports a 2-megapixel fixed-focus rear camera while a 0.3-megapixel front-facing camera is also onboard. The handset is backed by a 1560mAh battery rated to deliver up to 12 hours of talk time and up to 504 hours of standby time.
