The operator requested an extension over a year ago, to give it time to upgrade its TDMA networks to GSM. AT&T led the FCC to believe that as soon as the new networks were up and running it would provide the locator service. However, it turns out that AT&T has been distributing GSM handsets that do not have location capabilities.

The US telecoms regulator, FCC, is saying that AT&T has missed deadlines for the introduction of the service – and broken other rules – and must therefore pay the fine.
