Jio without plan B(3g) or C(2g). Review on Reliance Jio

Everyone of us know about reliance jio telecom and its mind blowing offers, I really appericiate that they have fullfilled their offers and they taught a lesson to every telecom operators who were charging a huge amount from their customers and they should learn from reliance jio telecom Pvt ltd.  Which was great, but I have noticed that jio 4 internet is slower than other networks even reliance jio 4g network is slower than 3 g network which other telecom operator provide their customers( us) now coming to the point reliance jio telecom only provides 4g networks and its is not possible to get signal everywhere, most of the times their signal doesnt reach us  how tragic and if it reach it very weak and when one use the internet or its network if their 4g signal drops their is no plan b, no 3g or 2g network to mantain the calls, that really frustrating, jio is totally not reliable, very weak signal slower connection without a secondry mode of network and their customer service they are too busy always working on the issue  now decision is yours
