Since 2007, we have collaborated with some of the largest Mobile Network Operators in the world, including T-Mobile, Verizon Wireless, AT&T, Sprint, Soft Bank, ROGERS, Telefonica, and many others. Our work has involved integrating their subscription management APIs, GGSNs with RADIUS for authentication, authorization, and accounting (AAA), as well as CDR interfaces for real-time alerts, analytics, and the development of customer billing systems. Our achievements are reflected in the satisfaction of our employees and customers, as well as our company culture. You can find our success stories at https://www.zintechnologies.com/case-studies/.
