Vodafone has extended a partnership agreement with Altice that sees it add the Dominican Republic to an existing deal in France.
The UK-based company has had a partner market agreement with French mobile operator SFR since 2002.
The deal enables SFR customers to roam in 26 countries where Vodafone operates, plus another 56 countries where it has partners.
In return, Vodafone customers get access to SFR’s network in France where it does not have an opco.
The agreement has been extended by four years until 2020.
Altice acquired SFR in 2014 and merged it with cableco Numericable.
In addition, Vodafone and Altice signed a similar deal related to the Dominican Republic.
Altice, which also owns Portugal Telecom, saw revenues decline 0.1 percent to €17.5 billion last year.
Turnover declined 3.5 percent in France, but Altice predicted an improvement this year.
Vodafone Partner Markets has deals in place with 37 companies in 57 countries.
Vodafone Partner Markets Chief Executive Stefano Gastaut said: “We are pleased to extend our long-standing relationship with SFR for another four years, enabling us to continue to bring our customers the best of Vodafone and SFR.
“I am also delighted that our partnership is now expanded to encompass Altice’s operations in the Dominican Republic, which means that Vodafone is now present in 82 countries, of which 57 are partners.”
