What is the reason for the bad cell phone signal

Poor cell phone signal can be caused by several reasons:

1. Signal blind area and weak signal area: The signal is lower than the receiving sensitivity of the mobile phone after loss, resulting in poor mobile phone calls or lower than the receiving sensitivity of the mobile phone after signal loss, resulting in poor mobile phone call quality.

2. Signal busy area: In areas with large traffic volumes, the base station capacity is difficult to meet the communication needs, and users cannot access the mobile network communication normally.

3. Signal conflict zone: The wireless signal in the high-rise building area comes from multiple communities, and most of them are unstable reflected signals from the ground and walls, resulting in frequent switching and seriously affecting the normal communication of mobile phones.

4. Environmental factors: For example, if the phone is located in the basement or in the elevator, the signal may be cut off automatically. The more complex the layout of the building, the more difficult it is to receive signals.

5. Mobile phone hardware: The SIM card in the mobile phone is an important carrier for our mobile phone signal reception. If the card is worn, this may make the SIM card unrecognized, readable, resulting in a poor signal.

6. Base Station Problems: If there is a problem with the base station that makes the signal sent not strong, the mobile phone signal will deteriorate.

7. Passenger flow: When there are too many people, the signal sent by the base station established by the same operator is limited and is collected by multiple people, resulting in the phenomenon of mobile phone signal being stuck.
