A statement from Telstra said the Galaxy S10 5G would be available first through the telco when the device was launched in Australia. Those who buy the S10+ will be able to upgrade to the 5G model.
The other three models — the S10, S10+ and S10e — will be sold in Australia after 8 March.
The new phones, apart from the 5G model, will be available in the US and the UK on 8 March. A foldable device will be available for sale on 26 April.
Telstra Consumer Segment executive Kevin Teoh, who was present at Unpacked where the new phones were shown to the media overnight, said: “Telstra has been a global leader in the testing, development and rollout of 5G in Australia and now our customers will be among the first in the world to experience it with Samsung.
“Under the partnership, the Galaxy S10 5G will be available through Telstra before any other Australian mobile operator when it is released in the first half of 2019."
Optus said the Samsung Galaxy S10e (128GB) would be available for lease on its 24-month My Plan Flex from $64 per month ($45 plan plus $19 per month handset repayments meaning a minimum total cost $1,536 over 24 months.
For the Samsung Galaxy S10 (128GB) a lease on the Optus My Plan Flex would cost from $69 per month. Customers can lease the S10+ (128GB) from $79 per month.
All Optus customers who place pre-orders by 7 March will get a pair of Samsung Galaxy Buds free.
