Why can't I call when it thunders?

Especially for computers, lightning can easily damage computer hardware and networks. Even if the computer has a good grounding wire, it is best not to surf the Internet, because lightning may invade the equipment along the signal wire and damage the chip and interface of the computer motherboard.

When it thunders, the magnetic field of mobile phone will change to some extent, but it is not enough to pose a threat to people's health. The frequency of mobile phones is as high as 900 to 1800 MHz, while the frequency of lightning is only a few tens of MHz, so there is generally no problem.

Thunderstorm weather, if it is in a building with lightning rods and electromagnetic shielding, it is no problem to play mobile phones and WeChat, and its danger can be basically ignored. Electrical appliances connected by wires are more dangerous than mobile phones.
