The cell phone signal in the room is very poor, so I can't receive calls and text messages. Is there any way to solve it?

There may be something wrong with the cell phone and signal.

In addition, it is best not to make a phone call when there is only one signal.

The transmission intensity is more than 1000 times different from that when only one cell is left. Therefore ... people who often talk about mobile phones ... should pay attention to ... 0. I got a very important message from a mobile phone manufacturer yesterday, that is, when you find that the reception intensity of your mobile phone is only one cell, you would rather hang up or change to a public phone. Don't talk too much. As we all know, the electromagnetic wave of mobile phones has always been a worrying problem. The design of mobile phone will enhance the intensity of electromagnetic wave emission, so as to maintain considerable call quality in areas with poor reception. When the reception is full and there is only one cell left, the transmission intensity difference exceeds 1000 times. The electromagnetic wave intensity is as high as 0.6W (Watt). How strong is 0.6W? I can't describe in detail what bad effects it will have on your brain, but I can compare it with two examples:

1) turn up the volume of a small radio with a speaker diameter of about 4 cm and stick it to your ear. The noise energy is generally 0.25W, less than 0.5W W. ..

2) Put your finger in front of a laser beam with an output intensity of 0. 1W (equivalent to that of an optical fiber network? You will feel burning pain in a few seconds. Can you stand these two situations for a long time?

Then how can you be sure that 0.6W electromagnetic wave will be fine if it is attached to your ear?
