Similar to traditional landline Caller ID, Name ID securely accesses operator-validated name information managed by TNS, and displays it on the incoming call screen to reveal the name, city and state of previously unknown callers who are not stored in a mobile phone's contacts or address book. The enhanced Caller ID service is engineered by Cequint, a wholly-owned subsidiary of TNS, Inc. Name ID is now available from T-Mobile on the Samsung ExhibitTM 4G, and will soon be available on additional handsets including the T-Mobile myTouch® 4G Slide expected to be available this month. SEATTLE, WA - JCequint announced today the availability of Name ID from T-Mobile USA, Inc., the first implementation of Caller ID - one of the most popular features in the history of telecommunications - by a major wireless carrier in the U.S. T-Mobile Customers Gain More Control over Mobile Calling Name Caller ID Introduced to Wireless by T-Mobile USA Update: So looks like T-Mo was not first out the box with wireless caller ID here in the US: MetroPCS has offered it for some time and Sprint partnered with Privus Mobile back in March to offer similar features.

At first only Exhibit 4G owners will be able to sign up, but other handsets (including the myTouch 4G Slide) will be added to the list of compatible devices later. Of course, this sort of convenience doesn't come free - T-Mo will be charging $3.99 a month for Name ID service. Any match is displayed when you receive the call and, if the person isn't already in your phonebook, you can easily add them with a tap. Instead of just checking an incoming call against your list of local contacts, the number is also fed through a larger database of publicly listed ones. There were a number of technical hurdles that stood in the way, but today those are officially crumbling as T-Mobile is launching Name ID in conjunction with Cequint, the company behind City ID. But, the truth is, until now true caller ID has never been available from America's wireless carriers. If you're still rockin' a landline you probably take caller ID for granted at this point and, if you're a mobile only kinda person, you might not even realize your cellphone lacks it.
