Telephones
In public telephone booths, coins and special cards can be used. They are sold in Portugal Telecom shops, post offices and some kiosks and news-stands (with a sign indicating this).
All telephone numbers in Portugal are composed of nine digits. To call from abroad to Portugal, it is necessary to dial the international access code 00 and the country code 351.
To call abroad from Portugal, dial 00, the country code, the area code and then the number wanted. The dialling codes of the various countries are affixed in public telephone booths.

Mobile phones
Portugal is one of the countries with the highest number of mobile phone users.
There are three network service providers - TMN, Vodafone and Optimus – that have roaming agreements with most international mobile phone companies and provide users with a good coverage nationwide.
The Portuguese Highway Code forbids the use of mobile phones while driving, unless you’re using hands-free equipment or an earphone, and there are established penalties that can be applied in the event of any infringement.

Internet
Internet access is available on payment in some cafés and in numerous post offices that have the Netpost service.
In various hotels and public facilities, like Airports, Conference centres, Restaurants, Service Areas in motor-ways and shopping centres, there are duly marked "wi-fi" areas where it is possible to access wireless Internet.
