From trunk calls to mobile phones

There was a time there were many barriers for people who wished to communicate. People had to book trunk call and patiently wait for the operator to connect to the other party. There was no privacy; technically the operator could eavesdrop on the entire conversation. Then came the PCO. But people still had to walk a little distance away from their homes. The mobile phone now has transformed everything where it does not matter whether you are lying on bed or in the toilet– it’s possible to communicate without any barriers of time, space or distance.
