If you wish to minimise the cost of using the directory enquiry service, you can request the relevant telephone number from the directory enquiry agent and state that you do not wish the call to be connected to the telephone number. The directory enquiry call will then end. You may then dial the relevant telephone number separately, meaning that you will be charged for the call at a standard rate and will not pay the higher directory enquiry rate. If you are using a mobile, check if a text service is offered as having the number sent to you will likely reduce the cost. Remember that depending on which network you are connected to and the nature of the specific telephony plan or bundle that you have with your service provider, it may be cheaper for you to use a specific directory enquiry service.
