Learn English – Is the sentence “Queueing is so thoughtful of you.” grammatically correct

Both of these are acceptable, though the focus in each is different.

By placing different parts of sentence at the front, you make them more important.

In the first sentence, the focus is on communication and the inability to do it. You could extend this as follows:

We could not communicate through the phone, though we could use it to (do something else).

In the second, the focus is on the phone and its uselessness in the situation. It could be extended thus:

Through the phone, we could not communicate but through the (something else), we could.

This works when written. However, in spoken language, stress and intonation could alter the focus regardless of word order.

As a matter of preference, I would tend toward the first example, simply because it is the natural order of the sentence without clauses being juggled and extra punctuation being added. I would only choose the second if I specifically wanted to alter the focus, as explained above.

Hope that helps.

It is removed is grammatically correct, but is not something people normally say. It sounds quite stilted.

The only context I can think of would be as a reply from a "right hand man" to his boss, if the right hand man was particularly well spoken:

Boss: This room is too cluttered. Remove this obelisk.

RHM: Yes sir.

(RHM gestures to minions. Minions remove the obelisk.)

RHM: It is removed.

A much more common idiom is it is [far] removed from X which implies the thing that it refers to is [very] different to X.

E.g.

This chaise longue is far removed from the stools of your hovel, eh?
