Try to fool people with text messages

I have an absolute classic! Try it and you'll know:

SMS content: Enter *#06# on the mobile phone, and press the dial key when making a call to display the number of the mobile phone device and check the authenticity. As we all know, today I'm going to tell you about a new technology. Enter **2 1*999999# on your mobile phone, and press the dial button when you call, and you can find your global positioning. Very advanced technology, I only told you. ...

Actually, you can't do GPS. This is a lie to him. After sending the above short message, as long as he operates through short message, he can enter **2 1*999999# on his mobile phone and press the dial key when making a call, and when someone dials his phone, his number will become blank.

Just enter ##2 1# and press the dial key. To get back to normal. It's free, haha, try it.
