Will Unicom automatically lose its signal when it receives too many text messages?

No. The signal strength is related to the surrounding base stations and cell phone antennas. , has nothing to do with receiving text messages.

Cell phone signal is an electromagnetic wave called radio wave.

Radio waves refer to electromagnetic waves in the radio frequency band that propagate in free space (including air and vacuum). The shorter the wavelength and the higher the frequency of radio waves, the more information will be transmitted in the same time.

The propagation modes of radio waves in space are direct, reflection, refraction, penetration, diffraction (diffraction) and scattering.

There are many kinds of electromagnetic waves, arranged in order of frequency from low to high: radio waves, infrared rays, visible light, ultraviolet rays, X rays and gamma rays. Radio waves are distributed in the frequency range below 300 GHz.

Radio waves in different bands have different propagation characteristics.

The lower the frequency, the smaller the propagation loss and the farther the coverage distance, the stronger the diffraction ability. However, low frequency resources are scarce and the system capacity is limited, so low frequency radio waves are mainly used in broadcasting, television, paging and other systems.

High-band frequency resources are abundant and the system capacity is large. However, the higher the frequency, the greater the propagation loss, and the closer the coverage distance, the weaker the diffraction ability. In addition, the higher the frequency, the greater the technical difficulty and the higher the system cost.
