Reliance jifi is a wonderfull device for 3g phones it can be used in 3g phones and can be also conneted to the laptops . In this device total 31 users can be connect at a same time and it is very fitfull to every one because it is easy to carry and as if it is very same in size as if from a mobile phones. So I prefer all the 3 g user to get a reliance jiofi and enjoy your 3g phone as 4g phone . thank you
