At a time when feature phones with better specifications are becoming a rage (you can't miss the upcoming 'intelligent' JioPhone and the quintessential Nokia 3310), Russian company Elari has launched NanoPhone C which, it claims, is the world's smallest GSM phone.

Weighing only 30 grams, NanoPhone C in rose gold, black anthracite and platinum silver colour variants can be purchased from e-commerce site yerha.com at Rs 3,999.

The phone was, however, launched for Rs 3,940 in July in India.

In terms of specifications, it has a microSIM card slot, a microSD card slot, built-in FM radio and an MP3 player as well.

Elari NanoPhone C also has basic features such as a 3.5-mm standard headphone jack and a microUSB port for charging the phone and syncing data. It measures 94.4mm x 35.85mm x 7.6mm and features a tiny, 1-inch TFT display.

The NanoPhone C directly competes with the likes of Nokia 3310 (2017 version) and aims to give users a shot of "digital detox", but does it live up to the hype? Let's find out.

Here is what works for the device.

The fact that it smoothly synchronises with Android devices (we paired it with an Android smartphone) via Bluetooth is commendable.
