Reliance Jio introduced the JioFi 3 back in 2016, which we unboxed in early 2017. Last year the company seems to have silently introduced JioFi 4 (JMR1140) and JioFi 5 (JMR814). Now the company has started selling JioFi JMR815, which should be JioFi 6. This measures 74 x 74 x 20mm and weighs just 95g with a 3000mAh, which is bigger than the previous JioFi models.
It has indicators for battery, signal and WiFi and has power and WPS buttons. There is a micro USB port for charging. It has a Altair ALT3800 processor, supports band 3 (1800 MHz), 5 (850 MHz) and 40 (TD 2300 MHz) for Jio.
It has WiFi 802.11 b/g/n support, similar to other models and lets you connect up to 31 WiFi-enabled devices and a device through USB cable. It also has a microSD card slot that accepts cards up to 64GB. You can make voice and video calls even on a 2G/3G phone by installing Jio4GVoice (JioJoin previously) app and connecting it to the hotspot over WiFi.
The JioFi 6 is priced at Rs. 999 (MOP), but the MRP mentioned is Rs. 2,499. It is currently available from Flipkart.
