With international roaming, a user of the mobile telephone service is able to make or receive voice calls, send or receive data (including SMS, MMS and Internet access) or have access to other associated features when travelling abroad, without needing a new number.
Considering the importance of international roaming for the development of communications, ANACOM provides information about the service in this area, and in particular information related to tariff transparency, thereby helping to ensure that users are properly informed.
Companies can also consult the available wholesale roaming offers from mobile operators.
