The services, operated on behalf of Mariposa Holdings, are live with Oi and Algar Telecom, two of the largest telecoms companies in South America.
It represents a significant expansion in 7digital's South American business, the company told investors, adding that services like these are key to the growth strategy.
7digital also revealed an agreement has been signed with Playster, a multimedia streaming group, to expand a music streaming service into 15 additional territories.
The deals with Mariposa and Playster are expected to contribute to 7digital’s 2016 revenues.
"The service launches with Mariposa show both the importance of mobile music to the company's growth and our ability to work with partners to generate revenues in markets that have been previously under served by strong digital music offerings,” said chief executive Simon Cole.
“In addition, our partnership with Playster aligns with the company's strategy to support customers who pursue business models that target more mainstream audiences."
Mariposa, in June, agreed a deal to license 7digital’s streaming technology and catalogue management platform and the first of the two services (via Algar Telecom) launched in October and the Oi services followed with launch earlier this week.
