Happy new year everyone.. Here is the issue. A couple of weeks ago I had a missed call on my cell phone. It was a witheld call, so I could not know who was calling me. After a minute or two, I had an SMS from my GSM Company. The SMS was a kind of spam. It was like " Do you want to know the number of your witheld calls, send an sms to some number and learn it bla bla" It seems they watch our call history. Then today, just after calling my friend who lives in UK (I am in Turkey) another SMS appeared, saying: "Call UK numbers with the same price in your country..." I am sure they are watching our calls and send sms's related to our calls. So is this a kind of spying activity?, my GSM company is the biggest one in my country. Nearly everybody uses them. Thanks for your comments.
