My friend enthusiastically bought me an artifact, which was a mobile phone signal sticker, and we talked about it. When he bought it, the merchant described it to him: We all have special stickers in our mobile phones. The wavelength of the received signal, as long as you put this mobile phone signal sticker on the back of the mobile phone, you can expand the signal reception range, and you can receive the signal no matter where you are. However, experiments show that signal stickers have no effect, especially when tested in the subway or elevator. After the signal sticker is applied to the mobile phone, the signal will drop.

I then searched the Internet for comments on related mobile phone signal posts. Many netizens said that this product is a proper IQ tax product and can completely constitute a fraud. Some netizens said, if this signal sticker is so useful, wouldn’t the three giants of mobile phones think about this issue? But more netizens said that they bought this thing because it was very cheap, so they bought it and tried it!

So I searched for the price and sales volume of related products and found that the price of mobile phone signal stickers is also very cheap, and the cheapest one is as low as two yuan a piece, which is very suitable for the public. It’s an acceptable range, so it’s no wonder the sales are so high. But what I want to tell you here is that there is no antenna connection in this type of product, and it cannot achieve the function of enhancing the signal through the air. Even according to scientific principles, the wavelength of the signal cannot be stretched. Furthermore, if this signal sticker is so useful, the three major operators of the mobile phone cards we usually use will immediately launch such products, instead of spending more money to build base stations and try to increase the coverage of the signal. , just buy a mobile phone card and get a sticker as a gift, wouldn’t there be a lot of things left?

Nowadays, various products are emerging on the Internet in an endless stream. I hope everyone can think more and never pay this kind of IQ tax, especially for middle-aged and elderly people. Although it is very cheap, the province has to pay it. Save it!
