China on Sunday said goodbye to 'dial telephones' when the last such unit was replaced with a state-of-the-art wireless unit in a remote Tibetan village, the state media reported.

The old telephones, operated by rotating a disk with numbered holes, had been used at Menzhong village in Nedong County of Tibet since 1974. China Telecom has invested US $17 million to set telephone networks to ensure that all the 683 counties and towns in Tibet are able to communicate with outside by wireless telephone. Around 17,800 families have joined the network since its launch in 2003.
