Mypolonga, Nildottie, Ettrick and Marama will get new mobile phone towers thanks to a federal and state mobile black spot program, Regional Services Minister Bridget McKenzie has announced.
The towers, among 22 to be built in South Australia, should be built during the second half of this year.
They will be jointly funded by the federal government, state government and Optus.
Liberal federal MP Tony Pasin said improved coverage would make regional residents safer and more productive and provide a better experience for tourists.
The federal government committed to offering two more rounds of funding, worth $160 million, prior to the election campaign.
The next round is already open.
