Its has been 8 months I am using this jiofi for my internet usage. I was not able use jio as I was using 3g phone but after buying this I was able to use jio network and also able to call from this by using jio4gvoice. the connectivity is really good and as my native is a village no problem or there was no issue of speed and it also has a good battery backup also as it lasts almost for 2 days in a single charge . I would definitely recommend this product for those who wish to use 4g network in their 3g mobiles. only thing is that I was not able use jiotv with it in my mobile .
