The cost of the phone is RRP but you get a free Google Next Hub Max if you pre-order.
The Nest Hub Max is currently $349 (JB, Harvey Norman etc) but looks like you will be required to be connected to the Telstra network for at least 1 month as you get a promo code for the Nest Hub Max that you redeem from the google store (cheapest plan is $55 per month but does not include access to Telstra's 5G network).
weird selling a 5g phone without access to 5g from the carrier. or is this an extra payment on top of the plan?
