The TNS Wireless Signaling service supports GSM-MAP and the industry standards for inter-switch signaling that enable seamless roaming, including call validation, cross-protocol roaming capabilities, SMS and automatic call delivery.

TNS has been providing GSM signaling since 1999, and supports both ANSI and ITU protocols including full support for ANSI/ITU protocol conversion and the associated MTP, SCCP, and Global Title conversions required to support international roaming. 

With direct connectivity to major GSM operators and gateway access to other GSM networks, subscribers are able to roam freely with access to all the features they are accustomed to in their home serving area. 

Our seamless roaming solution, when combined with other TNS data-mining and roaming services, such as the TNS Roamer View service, provides real-time information for troubleshooting and monitoring as well as useful reports for strategic planning.
