Some of the issues raised by readers include, calls dropping out and text messages not being sent in a timely fashion.

One reader said he was considering installing a tower to ensure greater connectivity for his oyster business.

Telstra's regional general manager says customers experiencing faults should contact the telecommunication giant's hotline.

Mike Marom was responding to issues expressed by customers and readers in our post.

Customers told the Port News they were experiencing issues including calls dropping out, text messages not arriving in a reasonable time and poor connectivity.

Mr Marom said there were a number of ways coverage can be impacted, including topography.

"The increase of data use - which is around 50 per cent - can also cause congestion," he said.

"It could be degrading of the service because of that congestion, however if it is a long-standing issue it could be topography.

"We would certainly be wanting to talk with any customers to understand their particular issues and to provide some possible remedies.

"For some customers in-building coverage can also cause problems, but there are solutions to that as well," he said.

"We want to talk with any customers experience difficulties."

Mr Marom said Telstra is working hard to upgrade its facilities which could also alleviate some of the issues with connection.

"By providing more bandwidth we do overcome some issues linked to congestion," he added.

The general manager also pointed to the benefits of rolling out 5G.

He said while this provided a new service it also increased bandwidth for 4G customers which also assists in providing better coverage.

Oyster farmer Paul Wilson described his Telstra coverage on the North Shore as "unbelievably bad".

"We had a great service up to about 12 months ago but now I am down to using wifi to talk with customers," he said.

"We have been battling this for some time. I've even considered putting in a tower to see if that helps.

"But the Telstra service is poor."

Mr Wilson said he had considered installing a tower to gain greater telecommunications connections.

Innes Lake resident Gen Delves said her main concern was the phone reception.

"Our phone service is pretty unreliable," she said.

"My phone will tell me I have service but I am unable to send text messages and sometimes people have told me they've received a text message from me that is dated.

"We've been here about 12 months and we don't really have a phone service and we rely on wifi.

"We also regularly get a message saying that a text has failed to send too.

"I also travel a bit between here and Sydney and the reception on the highway is very limited."

A Crestwood says her text messages "spiral endlessly" and sometimes don't even send.

"Text messages can appear hours after they've been sent," she added.

Sanctuary Springs' Austin McDonald says he has experienced connectivity issues for six or seven months.

"Calls will drop out so you can be talking to someone and then suddenly they're not there," he said.

"And you have to, sometimes, resend a message multiple times just to get it through the system.

"I also look at my call log and it can show that someone has called me, but the phone only rang for a second while the caller says they were getting a dial tone for a long period of time."

Mr Marom said customers experiencing poor connection issues can talk to a local network expert through the Telstra website.
