How did my grand parents communicate

As my grand parents lived in Afghanistan, which is one of the poorest countries of the world, their main communication was through mail which took almost a month to be get

from one city to another. This was only good for the very few people that had Knowledge of writing and reading. Those who were illiterate would pay some one to write the letter

for them and pay again for some one to read the letter for them. The second source that came earlier was the tel-communications which would cost more and u had to go to the

center send a message to the person and fix a time for the person whom you talking to should also be present at the center in his or her city for you to talk. A lot of difficulties at the

time when they were communicating. Fortunately mobile phone is the leading source of communication in Afghanistan right now.
