How important it is to keep in touch via text when you can't be face to face with a person?

I am of the opinion that texting is both bad and good. At some point it's fake as you don't understand in reality how the person you are texting with is feeling, but I think it's a good way of not losing contact with people that matter to you in real life. However I understood that people tend to behave different via text than they do in real life. So what is the point in texting after all if it supposedly was made for you to be closer to your people but at the same time it's making you distant and unreal?
