We chose TNS because they were able to provide all of the SS7 services we required and, despite being a global company, they delivered a personal touch that we highly value.

Cellular One Selects TNS to Deliver Latest Wireless Services


Founded in 1991, Cellular One of East Central Illinois is an independent wireless communications provider based in Danville, Illinois. Cellular One’s focus is to deliver advanced services and the latest cell phone offerings to the local community, combined with outstanding customer service. Cellular One employees are active in their communities and are involved with a number of local charitable programmes and non-profit organizations.

Business Challenge
To effectively compete alongside national providers and meet customer expectations, Cellular One must continually upgrade its systems to the latest technology available. This requires them to make decisions and then implement changes quickly. Cellular One required a supplier who was responsive to requests and that could effectively deliver a range of high quality SS7, Clearing and Messaging services. All of this must be accomplished while also maintaining a personal touch with customers.

Since 2009, TNS has delivered a range of wireless SS7 services to Cellular One, including A-Links, Number Portability Services, ISUP Trunk Signaling, TCAP CLASS Services, GSM MAP Transport and Settlement and Exchange Services for GSM. TNS also provides its intercarrier messaging gateway which allows customers to send text and multimedia messages across networks regardless of technology or device compatibility.
