BlackBerry said it would not renew a deal allowing T-Mobile US Inc to sell its products, a gamble by the smartphone maker as it struggles to stabilize its business under an aggressive new chief executive officer.
The move comes just six weeks after a public spat between the two companies, as T-Mobile offered its customers the Apple iPhone 5s for free in February and touted the promotion as "great offer for BlackBerry customers."
A backlash to the iPhone offer prompted T-Mobile US Chief Executive John Legere to respond, assuring Blackberry and its users of his company's support. Chen, in a blog post at the time, criticized T-Mobile for running the promotion.
In a statement late Tuesday, BlackBerry said it would continue to provide service to existing customers on T-Mobile's network or those who buy products from the carrier's remaining inventory.
"BlackBerry has had a positive relationship with T-Mobile for many years," BlackBerry Chief Executive John Chen said in a brief statement. "Regretfully, at this time, our strategies are not complementary, and we must act in the best interest of our BlackBerry customers. We hope to work with T-Mobile again in the future when our business strategies are aligned."
BlackBerry did not elaborate on why it was ending its relationship with T-Mobile U.S., the fourth-largest wireless carrier in the United States. T-Mobile could not immediately be reached for comment.
