Telstra and Vodafone will both start selling smartphone plans with unlimited data for the first time, following from rival Optus' similar offer that ended last month.
Telstra's mobile plan costs $69 per month on a 12-month plan and includes unlimited data with uncapped download speeds for the first 40GB. After that, users can still use data, but it will be capped at 1.5Mbps, which Telstra said would be "fast enough" to stream video and music.
Telstra's unlimited plan will go on sale this Thursday.
“We know how important it is to our customers that they can access the fastest speeds available to them on our network," said Telstra group executive of consumer and small business Vicki Brady.
“We have invested billions in our network, pioneered world-leading 4G speeds and pushed our 4G coverage out to more than 99 percent of the population. We are now introducing the unlimited plan Australians tell us they want while maintaining the superior network experience they expect.”
Vodafone has three similar plans all with unlimited data. The cheapest plan costs $60 per month with 30 GB of uncapped download speeds before also being capped at 1.5Mbps. The other two plans cost $80 per month for 60 GB uncapped download speeds, and $100 per month for 100 GB uncapped.
One of the key differences between the two telco's plans is that Vodafone will also bundle in a smartphone, Telstra's plan is BYO phone only.
Rival Optus put unlimited data plans on sale for a short time in March, and again last month to "eligible" customers, at $60 per month, though customers are capped at 1.5Mbps speeds when streaming video. Optus' unlimited plans are no longer available from its website.
