I use a phone vs I`m using a phone

"I am using a phone" refers to some activity you are doing right now. However, it would probably be better said: "I am using the phone."

A. Can you come here, now?
B. No, I can't, I'm using the phone.

"I use a phone" is a generalized statement about some activity you do repeatedly. By itself, this phrase doesn't make much sense. Here is one context where it does:

I mean using a phone in general (not necessary every day).

AnonymousI mean using a phone in general (not necessary every day).

In that case "I'm using a phone" suggests some temporary state of affairs. It may require some unusual scenario to justify this usage.

Please make yourself more clear. The same as what? Can you write the two sentences you think are the same in meaning?

Which tense we use when we want to say about something we do in general but not necessary regularly. For instance, about using a phone in general but not necessary every day or about studying English in general not in this particular moment. I hope I express myself clearly this time.

I am studying English means that this is an activity that you do in the general present. You are not necessarily doing it at the present moment unless context shows that you are.

Is that clear enough? We'll deal with the phone after we've got this cleared up.

In those cases we use the simple present.

Thank you very much, CJ! Now everything is clear to me.

Good luck.
