A few days ago I got a call from someone which I didn't want to receive. So I simply ignored it. That person called three times but I didn't pick up the phone and the phone kept ringing (or may be I disconnected every time don't remember exactly).
After that I got a message from UFone that if you want to block unwanted calls then simply send SMS to bla bla bla.....
Isn't this clever thinking by UFone!? I liked it. I mean if a person is not picking up calls then it could be unwanted call so they sent me SMS right after that haha
Another thing happened today. I didn't have balance and went to their website to check how to get ULoan or UAdvance of Rs.15 whatever they call it. And right after I visited that page I got an SMS from Ufone about that ULoan thingy haha!
Now the question arises how did they get my number as I just visited their website? It could be that I was once registered online....that online SMS you send...and they may have stored a cookie in my browser...and when I visited that page...they sent me SMS.....but that's a long shot and it could be coincidence
