I have a ufone mobile number. I used it rarely because I do not live in Pakistan and have it only for the short visits I make a couple of times a year to Pakistan. Only my close friends and family know my ufone number. I do not even use it for WhatsApp. Still I get almost 5-10 spam text messages on daily basis while I am roaming out of Pakistan. The only possible reason is that ufone or some one from ufone is selling consumer phone numbers to advertising companies and benefiting from it.

Its important to always create awareness against such malpractices and not let them go unreported.
