How can sunspots affect cell phone communication?

First, allow me to explain what makes up a sunspot: flares and CMEs, both of which are extremely dangerous solar radiation sources; flares are the release of energy, while CMEs are the sun's outflow of non-plasma.

They disrupt satellite-directly connected electrical devices like televisions, radios, and cell phones when they crash into the Earth's atmosphere. This destroys electric grids and interferes with communication because of the radiated energy.

Sunspots are regions of high magnetic activity on the surface of the sun that can emit bursts of radiation, including radio waves. These bursts can interfere with the radio signals used for cell phone communication, resulting in dropped calls, poor reception, or temporary loss of service. Sunspots can alter cell phone communication through disruptions to radio signals.
