Karbonn A40 4G price in India: Rs 2868, Rs 1399 effective price with Airtel

Karbonn mobiles, the Indian mobile giant has tied up with the Indian Telecom giant, Airtel for a kickass 4G smartphone experience at an unbelievable cheap price. Primarily competing with Reliance JioPhone, the new Karbonn 4G phone is one of the cheapest smartphones you can buy online in India. But is it worth investing? Well, we take a dig at the Karbonn A40 4G specifications to learn whether it's worth investing or not.

What’s hot?

Android 7.0 Nougat experience and the Good battery life.

What’s not?

One cannot complain much about a cheap smartphone specs sheet.

Design & Display

When you’re looking to buy a cheap smartphone in India, you don’t and shouldn’t really concern yourself with the design. But Karbonn didn’t introduce its cheapest 4G smartphone in the market with such attitude. Instead, it has introduced a phone with superior build quality in its class. Further, the new Karbonn mobile sports a 4-inches 480p resolution display, which is ideal for the price point. You won’t enjoy the vibrancy or the saturation, not even the viewing angle, but it can be considered as the standard display panel.

Performance & User Experience

Running on a Quad-core processor from the house of Spectrum, the chipset said to clock at 1.3 GHz. The 1GB RAM and 8GB internal storage surely make up for a good support. If you have any media storage concerns, then, you must know that the storage can be expanded up to 32GB via microSD card slot. Offering a 4G connectivity in this price range makes it a worthy smartphone. It comes with a dual-SIM connectivity, which means you can simultaneously run two phone numbers on one device. Karbonn teases the Android 7.0 Nougat OS based user interface on this inexpensive 4G smartphone.  


Not made for intense photography, this Karbonn mobile comes equipped with a 2MP rear camera and a 0.3MP selfie camera. Of course, it isn’t much, but Karbonn claims that it should be sufficient for clicking and sharing photos on social media and messaging platforms like Facebook and WhatsApp. Interesting to note, there are several camera modes available on this device including Panorama, Selfie, Burst, QR code, Smile shutter, and Gif mode.


A 1400 mAh capacity battery is considered to be quite large for the display size it comes with. Karbonn mobile claims to offer a 4 hours of talk time and 200 hours of Standby time, which is quite brilliant.      


Whether you’re buying this device with Airtel offer or not, we believe it is a good device for the specifications it comes with, even at its original cost price. But if you’re buying with the Airtel offer, then, it really is a great smartphone.
