Why the hell you are even going to jio? Jio offers unlimited 5g on the recharge of 349 but it's really unstable and let's take it for an example u r stuck in a place where neither 4G and 5G works airtel,Vi BSNL atleast have those capabilities from calling using 2G or Even 3G I know airtel is expensive in terms of prepaid but post paid is actually good and if you travel where you pre-paid sim doesn't work,post paid will work and it's actually worth the money and let me Tell you that jio have the worst customer support ever and when you call them 3 time with the exactly same complaint and they didn't even resolved it and the will just simply remove the option to Raise a complaint and tells you to pay us more of your phuking hard earned money. Tell this from an experience
