I am using two airtel no and in both i have data plan 1.5 gb per day
Today 3:00 pm i connect my data 3:36 i got message that you have used 90% of data then again 3:40 i receive message that you have used 100% data
So i change my sim and connect the net throw 2nd sim after 7 minute 3:47 i got message that you have use 90% of data. (See attached of screen shot)
Since one week i am facing same problem. 5-6 times i call to customer care but always they told me please off auto update, don't watch hd video, what is this yaar kiya isse pehle hum ne net hi use nahi kiya ya phir mera mobile har roj update horahah hai
Yes jio is the best pehele mai jio he use karta tha usme is tarah ka koi problem nahi thaa

Jab 90% ka message aata hai to ek aur message bhi poopup hota hai ke 3gb ka rechage kijye 48 me ek din ke liye
My question is
