[单项选择]BUSINESS TELECARD INTERNATIONAL
You can use your Business Telecard International at any card phone in the UK. Here is some information about making international phone calls.
You can now phone almost any country in the world, although in some cases you can only call major cities. When you cannot make direct dialling calls, you can ask the international operator to help you. This is more expensive and takes mere time, but it may be helpful if you want to speak to a particular person and no one else; in this case you should ask for a "person-to-person" call. Even more expensive is a reverse charge call where the person who receives the call pays.
If the international line is busy, you can reserve a call; explain the number you want and the operator will call you back when the line is free.
