International Roaming for the United States

In order to provide roaming to clients that travel outside Brazil, mobile operators partner with foreign service providers to offer services such as voice calls and data.

In this article, we will show which Brazilian carriers offer roaming services in the United States and what technology is used to this end.

It is common practice for mobile network providers to partner with one another, in order to provide telecommunication services when there are no proprietary antennas in some regions in Brazil. This is also the case in foreign countries such as the United States. Since Brazilians are travelling abroad more frequently, providers are making investments to assure their customers are still able to use their services even outside the country.

The United States has been for the past few years the main international destination for Brazilian travellers. In 2012, the country was visited by 1.79 million Brazilian tourists. It is estimated that the number of Brazilians travelling abroad grows around 7% each year, and between 2003 and 2012, the number of Brazilian tourists travelling to other countries increased 244%.

International Roaming in the United States

The five largest mobile network providers in Brazil created a partnership with two major North-American carriers. The services offered may vary slightly according to each operator, but in general they all offer voice, messaging and mobile data roaming services. These are individually charged per minute, message or megabyte used or included in packages, which tend to be the cheaper option. Note that the coverage area is limited to what is provided by each partner.

The technology used tends to be similar between the two major providers, AT&T and T-Mobile, only differing when it comes to the services they provide to Brazilian customers, such as availability of 4G data coverage. In order to assure the compatibility of these services with mobile devices, the frequencies available for roaming must be checked according to what is supported by each device.
