Is it true that China Telecom used the telephone number to log in and deduct money?

Not deductive, not true. Hotel China Telecom is a communication service provided by China Telecom for the hotel industry, such as Internet, fixed telephone, wireless business telephone and various industrial applications. It's not true that China Telecom logs in by phone number without deducting money. However, if you answer someone else's phone, you will face the cost of answering the phone.
