Question

how is telephone or a mobile better than a letter?​

Answer 1

Explanation:

because it was the fastest communication than a letter

Answer 2

A phone call is a speedier mode of communication than a letter, which takes longer.

We can listen to each other's voices on the phone, but not in writing.

I prefer making phone calls over writing letters. That is because when we call someone, we get an immediate reaction, however when we write a letter, we have to wait days for a response.
