I think that the advantages of the text msg, which is on of the modern means of communication are that they offer the possibility of texting. For example, when I am at school, I can write a text msg to my girlfriend.
In my opinionnot the phone but the video chatis the best invention of the century. The advantage of the video chat is that it gives us an opportunity to keep in touch withpeople living abroad. My sister lives in Poland, so my family call her every evening to see how she is doing and it helps us avoid sadness and the feeling of missing her.
I think that the phone is the most convenient means of communicationwhich we use to call , the phone isconvenient to use. I can call my relatives or my parents whenever and wherever.
I completely agree with Nastya, but I would like to add something more. In my opinion, the phone is the most convenient means of communication, because it wasn't only made for calls, but it's a pocket computer. Using only my phone, I can get to the how and the why of things. It's a cure for boredomand it's a helpful friend.
