Vodafone mobile customers are having trouble making calls and accessing the internet as the company experiences major outages across its 4G network.
The telecommunications company says it has identified the problem and is working to resolve it as quickly as possible.
“Mobile customers may experience difficulties making calls and experience slower data speeds this afternoon while services return to normal,” Vodafone Australia tweeted on Friday afternoon.
“Data services may be falling back to 3G intermittently, causing congestion and slower speeds.
“We apologise for the inconvenience and thank customers for their patience.”
Vodafone told AAP that if customers are using NBN for wi-fi, those services are not affected by the outage.
Mobile phone customers started reporting difficulties about 11am AEST, with complaints peaking just before midday, according to outage website downdetector.com.au.
Disgruntled customers from across the country have been venting their frustrations, with one saying: “Slower data than normal, try no data!”
“Literally on the phone to my partner giving him directions to get to his jobs because he can’t access maps,” tweeted another.
