Wallendbeen residents were without a landline phone service for three and a half days spanning last weekend due to a fault on the transmission line linking the township to the Telstra exchange in Wagga.
Up to 88 phones in the village were out from early last Friday morning until just after lunch on Monday.
Telstra apologised for the delay, which it said was due to the need to "source and replace new technical equipment".
The service failure left a number of older residents in potential danger because they had no way of contacting emergency help in a health crisis, given that they don't have mobile phones because they don't work in the village.
Wallendbeen, at the crossroads of the Olympic Highway and Burley Griffin Way, is a notorious mobile phone black spot for anyone with a Telstra-based service.
Despite numerous requests including letters from the Wallendbeen Community Association to the local state member, Steph Cooke, and the federal member Michael McCormack, Telstra point blank refuses to do anything to remedy the situation.
When asked this week NSW regional general manager, Mike Marom, said "Telstra currently has no plans for any upgrades or changes to mobile coverage at Wallendbeen".
Mr Marom said Wallendbeen receives Telstra mobile coverage from the Telstra tower located at Ryans' Lane, approximately 11 kilometres away.
"For people living in areas with patchy or minimal mobile coverage, there are a number of antenna options that residents can purchase to can assist with improving the strength of a mobile signal into their home," he said.
Another remedy may be to change to Optus, which according to some is OK.
