Cell reception in Yalata (South Australia)?

I would guess that it is very unlikely that there was mobile/cellular phone coverage at Yalata provided by any company. Could be wrong, There should be a landline connection at the roadhouse. I briefly checked the net but all I found in a few minutes were sites wanting me to change my phone plan. I clicked the coverage tab on one site and it ignored me. So to h*ll with them. Best bet is to call Vodaphone and ask them direct.
