The Mexican PTT Telmex has brought into service a credit card payphone system from GEC Plessey Telecommunications at the Benito Juarez International Airport, which enables direct International Direct Dial access without the need for local currency or tokens: the system accepts standard international credit cards and gives the user operating instructions through a series of voice prompts in Spanish and English; like similar systems installed in the UK, the phone displays the cost at the end of the call, which is then billed to the credit card account; the system can also provide services such as Freephone, Message Mail and Phonepoint.
