This is very good and small hotspot. We carry this jiofi any where. But now a days technology increases day by day and copitition also increases. Those pepole who want to use 4g network but they don’t use because of that their phone is not support 4g. The jifi is very beneficial to those persons. But now other company ISP also provide same scheme that jio provides 399. And their sims also support in every phone. So now jiofi is waste of money.
