A mobile phone black spot at Roseworthy is set to receive a boost, with a $600,000 partnership striving to tackle the problem.
The state government and Telstra are partnering to deliver the additional tower.
Member for Schubert Stephan Knoll said the new mobile phone towers were a great result for the local community.
"We have been looking to improve mobile phone coverage for years around Roseworthy, as it's essential for townships to stay connected, particularly now," he said.
"A reliable mobile phone service makes a significant difference for families, individuals and businesses living and working in remote areas. This will also improve safety for those in the Roseworthy area as well as open up new economic opportunities."
Telstra SA regional general manager Mark Bolton said Australians were relying on mobile connectivity more than ever before for making calls and accessing the internet.
"In an emergency having mobile coverage and being able to make a call can make a huge difference for people living in regional areas," he said.
Primary Industries Minister Tim Whetstone said the state government had long-recognised the importance of effective telecommunications as critical infrastructure for rural and regional communities.
"Mobile phone coverage and connectivity is vital for people living in regional areas, especially at a time like this, with the COVID-19 pandemic meaning people are heavily reliant on mobile coverage to stay connected," he said.
"Improved mobile coverage also leads to economic development opportunities for new and existing businesses and improved service delivery in areas such as health and education."
The $10 million state government Mobile Phone Black Spot Fund has contributed more than $8.7m to addressing 42 mobile phone black spot locations in regional SA.
