Sprint on Monday announced plans to open up to 500 new branded retail locations in a joint venture with European wireless and consumer electronics shop Dixons Carphone.

Sprint said the venture, which will be funded by the two companies in a 50/50 split, follows a “successful” pilot program last year that resulted in strong sales.

The expansion will help “fuel Sprint’s retail transformation,” the carrier said.

“Sprint is committed to providing the best possible experience for our customers and that begins at the retail store level,” Sprint CEO Marcelo Claure said in a statement. “Dixons Carphone is truly a global leader in the wireless retail industry. We have seen incredible results from our pilot program, and I’m confident that expanding our partnership will accelerate Sprint’s distribution expansion and ongoing retail transformation.”

According to Sprint, the agreement will see Sprint and Dixons Carphone Connected World Services build and operate new Sprint stores in several U.S. markets.

Dixons Carphone has previously worked with Best Buy to launch its Best Buy Mobile and Geek Squad programs.
