Humid conditions can have an adverse effect on cellphone signals.
Humidity can create situations that hinder a cellphone signals from reaching their destinations and can affect the device's ability to function properly. Humid conditions are mostly associated with weather conditions, but can also be associated with manmade humid conditions, such as indoor swimming pools and saunas. Humidity can also create situations that make your cellphone a hazardous piece of electronic equipment.
Rain and Snow
When the humidity level reaches 100 percent, precipitation is likely to occur in the form of rainfall or snowfall. Extreme conditions associated with these types of precipitation come in the forms of thunderstorms or blizzards, both of which can wreak havoc on cellphone signals as they attempt to connect to the 2G, 3G or 4G wireless networks. Cell towers, which act as relay stations for cellular signals, either retain cellphone transmissions during a storm or attempt to divert them to nearby towers for faster processing. Often, if the humidity associated with the storm is high enough, the cell signals will be unable to reach the cell tower, in which case the transmission is aborted. If the tower retains the transmission, it will send it as it normally would once the weather clears.
Internal Components
In humid conditions, a cellphone's internal components can experience condensation, an effect that can lead to corrosion and eventual failure of the device's functions, including sending and receiving cellular signals. Although the phone's exterior casing is designed to protect its internal components from external forces, there is only so much it can do to combat humid conditions. Keeping your cellphone in a plastic bag or wrapped in a towel while experiencing extreme humidity can help avoid damage to its internal components and eventual failure to send and receive cellular signals.
Extremes
When transporting a cellphone from one atmospheric extreme to another, such as from arid to humid conditions, giving the device time to adjust to its environmental surroundings will minimize the chances of malfunctions, such as failing to send and receive signals. This can help minimize the effects that can be caused by differences in temperature and humidity. On a smaller scale, but equally important, differences in humidity between rooms in the same building, such as a bathroom and a garage, should be taken into consideration when protecting a cellphone from the effects of humidity.
Lightning
Lightning, another potential danger associated with extreme humidity conditions, can also affect a cellphone's ability to send and receive cellular signals. Although direct lightning hits are rare and cannot be entirely protected against, it is possible to minimize their potential hazards and effects on cellphone functionality and signals. Turning the device off when a thunderstorm is present is the best way to minimize the potential adverse reactions a cellphone can have when electricity is in the air. These reactions can include spontaneous electric discharges that can cause the device to malfunction or can cause bodily harm to the user.
