+ factor in first month of mobile plan cost, you can just sign up and cancel plan which would cost you 1 month of mobile plan charge max (lowest is $35/month), alternatively if you want to stay at least 12 months then sign up with Shopback for cash back (12-month + handset = 65% cash back, 24 to 36-month + handset = 100% cash back. more info regarding this please contact ShopBack directly) or GoCashbackAU and Cashrewards :)
ALSO iPhone SE 64GB $549, LG Velvet 5G $799
12-month Amazon Prime subscription bonus for 60GB 100GB and 150GB plan, priced at $40, $45 and $65. So, best plan to stick with is 100GB for just $40 per month which would also save you another $59 from Prime subscription for a year.
No excess data charge, and no lock-in contract too ^_^
