“We continue to invest in our network to boost the capacity, speed, reliability of 4G and rollout our award-winning 5G network to even more Australians,” Optus said.
“Due to the increasing costs to maintain and provide a great network experience, we’ve made the difficult decision to increase the price of some of our mobile plans.
“Balancing the affordability of our products with the need for ongoing investment is a delicate task and we are acutely aware of this challenge, especially considering the vital role connectivity plays in our lives.”
