What happens when it thunders and rains and answers the phone outdoors?

. 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. You can't use your mobile phone when it thunders, which only means that lightning will damage the mobile phone itself.
