As per the image, picked up yesterday at JB HiFi in Fountain Gate [likely to be applicable other JB stores].
JB Exclusive BYO SIM offer!
Port a number to Telstra and receive a
$400 JB Gift Card!$59 per month (after $10 credit is applied for 12 months)
80 GB Data12 Month Contract
Minimum cost over 12 months $708.
Offer only valid for customers connecting a new number to Telstra.
Not available for customers porting from Belong or Boost servicesEnds 3/1/21
"… a new number to Telstra", should mean porting in from services that are NOT either Belong or Boost. Surprised that Aldi Mobile isn't mentioned, so it may be an option for porting.
So long as you have a use for the JB Gift Card, which doesn't expire btw, then you can say that it is effectively $308 for 12 months or about $26.67 per month. Obviously you get the gift card immediately and you will pay $59 per month for each of the first 12 months. I would expect an early cancellation fee to apply, naturally.
I recently ported away, not sure if it is long enough to port back in, but I expect to try and do so before the 4th of January (probably on the 2nd or 3rd for me).
NB: There is no mention of this deal on JB's website, you need to visit anyway, but the printout as shown in the image was at the shop entrance.
This deal https://www.ozbargain.com.au/node/593258 is better, but it's only good for the 26th December now…. (an extra $100 on the giftcard).
Was it 500 bucks G card last time?
