In the first case, there is no money for practical reasons. Because there is no money, you can't afford to make a phone call. Too many calls will stop. So this sentence is completely understandable.

In the second case, ta himself may be rejected, and then he and ta want to save it, but the other party always refuses. Ta thought of giving up, so ta would sigh like this. Maybe it's too difficult to talk to each other on the phone, so it looks extravagant. Finally, I had to make up my mind to give up;

In the third case, ta was chased or something, and then that person often called him, but he was too busy to answer the phone and chat, so he simply hinted to the other party, don't do it again, such harassment is absolutely impossible.
