| You can use your Business Telecard
International at any card phone in the United Kingdom. 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 big cities. When you cannot make direct dialing calls, you can ask the international operator to help you. This is more expensive and takes more 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(留下) a call, explain the number you want and the operator will call you back when the line is free.
