Those who are with Telstra have reported their phone calls cut out after less than a minute.

But, head to another suburb, dial a number, and they can talk for as long as they want.

One of these people dealing with this issue was Corrimal’s Sarah Bowley.

She had been struggling with super-short calls since December 30, until things got better this week.

“I can make a phone call and it would last maybe 40 seconds,” Ms Bowley said earlier this week.

“The longest would be a minute and 10 seconds.

“I work for my parents and they call me regularly. When they do call I have to constantly call them back, after a couple of seconds.”

But it only seemed to be an issue around Corrimal – Ms Bowley’s phone calls went off without a hitch in other suburbs.

“I can drive to Woonona and use my phone and it’ll work fine,” she said.

And she wasn’t alone – she said a number of other people in Corrimal with Telstra coverage had to keep phone conversations really short to avoid being cut off.

Ms Bowley said she'd contacted Telstra – via their online chat forum, because, obviously she couldn’t ring them on her mobile.

The telecommunications company said there were no network issues in the Corrimal area and suggested it was a fault with her handset.

But switching to a new handset didn’t put an end to the problem.

Also, the people she knew with the same problem all had different handsets.

A Telstra spokewoman threw some light on the issue of the very short phone calls that only seemed to affect a few suburbs.

“We are aware of intermittent disruption to some mobile services in the Wollongong and Corrimal areas and our field techs are currently in the area investigating its cause,” the spokeswoman said.

“We apologise to our customers for the inconvenience and assure them we are working to rectify the issue as quickly as possible.”
