My mobile phone is blocked.

I'm an international student in the United States. Oh, my God, my luck is not very good. I'm a Chinese. I'm back in my motherland to continue my studies, but I just came back and my mobile phone can't use it. The operator's lock is blocked. It's too sad. He said it was a fraudulent blacklist. The operator is T-mobile. I can't contact the after-sales staff in the United States now. My IMEI is 35 538025 745006 1 I hope the after-sales staff can help me solve the problem. Thank you very much. When I return to the United States, I will definitely thank you. The mobile phone is very important to me because he is to Study is very important.
