Telstra says it has been asked to shut down its mobile base station in Moama at different periods until December 12 due to third party works.
Customers will receive texts advising them of upcoming work, with the site needing to be switched off from Wednesday, December 4 to Thursday, December 12.
Restoration to the mobile network will happen at the end of each day.
Telstra customers can continue to make calls and send texts during disruptions by switching on Wi-Fi Calling, the company said.
Wi-Fi Calling is a free setting on most popular mobile phones, allowing the device to make and receive calls while connected to wi-fi.
Business owners are encouraged to talk to their bank about connecting EFTPOS terminals to wi-fi connections to prevent delays in processing transactions.
