I own the Reliance Jiofi device which is one of the worlds best mini portable wifi router. I bought it from 2000 rupees from a local nearby reliance store. The device is very small and easily you can carry in your pocket, since I use the 3rd generation so it has got an OLED display and the entire body is a matte finish.
You can connect upto 32 device and its battery is also very good, with 2600 mAh it really gives a very good back up, running upto to 6 to 7 hours. You get a charging adapter and usb cable along with it and it really takes very less time to fully charge.
There is three level of light intication, if the battery symbol is turned green than that means that the battery is full, if its blue than that means its 50% and if its red than it needs immediate charging, same with the tower signal and wifi signal. it has got only two buttons, one is the power button and the other is the WPS button.
You can also add memory card on it and the sim slot is on the back, the battery is removeable and you can’t use any other sim apart from Jio but than again why would one want to switch when jio is giving such a good package.
yes definitely you should buy this if you are planning to get one mini router and it is really value for your money.
