Without the internet, how can a mobile phone send messages to a computer?

When there is no network at home, although it can't be sent wirelessly, it can be very flexible:

1, spread by stupid methods. You can use the data cable of the mobile phone to connect computers to transmit to each other. Some mobile phone charging lines have USB, which can be used as a data line to connect to the USB interface of the computer for data transmission (that is, the process of copying and pasting).

2. The card reader can be used to connect computers and mobile phones for data exchange and storage. What kind of card reader has a mobile phone memory card?
