U.S. cable operator Altice USA will sell mobile service on wireless carrier Sprint Corp’s network under a new multi-year agreement announced on Sunday, becoming the latest firm to enter the wireless market in a bid to retain customers.
The companies announced the agreement a day after Sprint and T-Mobile US ended merger talks.
Under the terms of the agreement, Altice, the fourth-largest U.S. cable operator, will use Sprint’s network to provide voice and data services in the United States. It gave no time line on when it will introduce such services.
