What to do if the mobile phone fails to receive the signal?

Many people think that mobile phones without signals cannot be solved by their own ability. They think it is the communication operators who can solve this problem. In fact, it is not true. We individual users can solve the problem of no signal on mobile phones.

We first rule out the physical hardware problem, reinstall the SIM card and check whether the card slot and SIM card are damaged or deformed. Sometimes the SIM card is loose, resulting in poor contact. Or send it back to the mobile phone store for repair to check whether the internal hardware is no problem.

After excluding the physical and hardware factors, we can basically determine that the location cannot receive the signals transmitted by the base station. Evaluate the range you want to cover, and then call the operator to ask about the specific frequency band of your mobile phone's 2g 3g 4g 5g network. After writing down these two information points, buy a set of mobile phone signal booster online, provide the two information points just obtained to the supplier, and let the supplier recommend the most appropriate mobile phone signal repeater to you. We must choose good suppliers here, and don't be greedy for bargains. Because unqualified mobile phone signal amplifiers will cause great harm to the base station, and the average service life of cheap mobile phone signal booster is 2 months, while the average service life of qualified mobile phone signal repeater is 6 years. I believe everyone can do this simple arithmetic problem.

Next is the installation problem. First, find an outdoor place where you can receive mobile phone signals and install an outdoor antenna. One thing to note is the distance control. If the cable is too long, it will cause serious signal loss. You can't install antenna to receive signals 100 meters away from your home, can you? The mobile phone signal amplifier is connected to the outdoor antenna through the cable, and then to the indoor antenna through the cable. Indoor antennas are evenly distributed within the coverage area. If there are multiple indoor antennas to be configured, power splitter or coupler can be used for reasonable distribution.

After all this is done, the repeater can also receive signals in the indoor mobile phone after it is powered on. In the future, you will never be bothered by the lack of signal on your mobile phone.
