Firstly, I didnt find any General discussion section, so I am posting it here, if there is any other appropriate section for it, please move it.. So, I just wanna know that, why people say that you wont have any problem from ISP when u r using prepaid card and any trick. I mean, even if you have prepaid card, but u r using data more than there data pack.. In prepaid, u pay first and then use their services. But still, u r using more than the limit. We can say that there system has bug or something that data didnt deduct. But still they have proof that you did recharge of 1 gb plan and used 200 gb or something. Can anyone clear my doubt?? Postpaid ka to clear hai, u have to pay them after your usage.
