He began his career as a senior engineer for Southern Bell.

“I am thrilled to be joining the company at this time,” de Cárdenas said. “I look forward to working with Tony and the rest of the team as Syniverse builds on its excellent reputation among wireless operators to maintain its strong customer base in North America and continue to grow its business throughout all regions of the world.”
