People talked face to face, and wrote letters. They also sent telegrams.
Before the telephone, people generally sent letters to people in order to get in touch with them. United States Postal Service started in February of 1692. At that time, that it was the only way to communicate.
To send a telegram you had to hand deliver your message to a telegraph office. There, an operator enters the message into a telegraph, which then translates it into Morse code and routes it to its destination. And the receiving end, machines translate the encoded message back into words and print it out. The telegraph office hand delivers the message to the person receiving it.
