New Delhi,  August 13  2017:  We are used to nano SIMs after micro SIMs. Now say hello to a Nano phone -- the world's smallest GSM phone!
It is the Elari NanoPhone C, weighing just 30 grams, taking a micro SIM and a 32 GB microSD card  for expanding the built-in storage that is just 32 MB as is the RAM memory   Within its lilliputian size ( about 94 mm by 36 mm) with a 1 inch screen,  it houses MP3 player, FM radio, alarm and voice recorder ( recording incoming call to the SD card). There are no cameras.
The makers  don't expect   buyers to use this as their primary phone: rather they suggest you can pair it via Bluetooth,  with your main mobile phone ( iPhone or Android)   and call/receive from either.   Perhaps you may prefer to take a small-n-light phone with you when you  go jogging.
The Elari NanoPhone C costs Rs  3940 and has been brought to India by www.yerha.com
