Sure it may be legal but is it whats morally good? If someone / your employer entered into a contract with you to pay you for your legal services for a year and then efficiently breached the terms would you give them a high five and be fine with it? In your example, would you give AT&T a high five for efficiently breaching their contract and taking money from a subscriber? Also I'm not sure if you're using the right terminology. From Wex, Efficient breach: A breach of contract in which the breaching party finds it cheaper to pay damages than to perform under the contract. [1] You're not paying them when you unlock your phone out of contract so it wouldn't be efficient breach. It's just breach of contract. Also as you know it's not really breach of contract or not until a judge says so, so you can't just call contract violations that happen all the time an efficient breach. I have a bit of legal education from years ago and I understand that there are many things that are legally "right" but there are other things to consider too.
