"When 5G arrives to our customers with 5G devices, they will get 5G network access at no extra charge," said Vodafone CEO Iñaki Berroeta.

This will soon extend to Vodafone's $5 a day international roaming, which will soon include 5G access in the United Kingdom, Italy, Spain, Germany and Ireland. Other countries will be added over time.

"In the coming months, we will be leading international roaming into the next generation of mobile technology by combining the great value of our $5 Roaming product with a 5G network experience in five of Australia's favourite travel destinations," said Berroeta.

Vodafone is already planning 5G coverage at more than 650 sites in parts of Sydney, Melbourne, Brisbane, Adelaide, Perth, and Canberra. The first sites have gone live in the Parramatta area, with others following from mid-2020.

"Throughout 2020 our customers will see us deliver 5G coverage to more areas; with more 5G devices to choose from; while delivering the great value that Vodafone is known for," he said.

"We have more than 650 5G sites in planning, with thousands more on our roadmap over coming years."
