This deal needs a Telstra login but might work with a Boost account. I used an old Telstra account now linked to my Boost number. If you don't have a Telstra account, you need a Telstra mobile number, Telstra landline phone number or Telstra account number to sign up.
The price is only for outright and doesn't need a plan. When selecting an interest-free payment plan for the phone for 12/24/36 months you need to add a Telstra plan. JB Hifi didn't match this for me, according to them it's related to a service and you need to log in for this deal.
I hardly see people using flip series phones. They will still only when RRP is user 1k
