Difference between 送信【そうしん】 and 通信【つうしん】


I understand that they both mean to transmit or communicate, but I am having a
hard time understanding how they are used. I have seen them both used, for
example, on cellphones.

> メッセージを送信【そうしん】 in one messaging app
>
> メッセージを通信【つうしん】 in another messaging app

Is there a difference in the feeling, or is one more "correct"? Can they be
used in different contexts, instead of only being used in the same way?




送信 means outbound communication, 受信 means inbound communication, and 通信 means
communication in general. We also have a word 送受信, which explicitly refers to
communication in both directions.

So メッセージを送信 only means _sending_ a message. メッセージを通信 means both _sending_ and
_receiving_ messages.
