So the situation is that my Dad needs a usb dongle for his work. I checked all of them and found MTNL to be the best suited. Good unlimited plan. he sent someone from his office to mtnl's office and it turns out they are out of dongles and they don't know when they'll be in stock.So does anyone know from where in Delhi can an unlocked usb dongle be purchased? Can't buy it online as it needs to have a bill with company name and shit.
