Digital Communication Vs Voice Communication

SMS
The social disadvantages to communicating via SMS in text language are as following:
It can be difficult to gauge sarcasm and emotion without the aid of body language
It takes longer to communicate; it can take you minutes to type a text message that could take only seconds if communicated verbally.
It could actually cost you more to have a conversation via a series of texts then make a quick phone call.
Its impersonal especially if you want to ask a question or tell the person something important.
