Here are 2 good options for getting the most out of this starter pack. Before you activate make sure you get a referral code from a friend already with Belong or the OzBargain Belong pool for an additional $20 credit https://www.ozbargain.com.au/api/referral/35
Option 1 (4 Months 23GB) - Activate on the $25 10GB per month plan. When the 1st billing date comes you'll get another 10GB. Then switch to the $10 1GB per month plan for the 2nd & remaining months. The first 4 months cost is covered ($40 starter pack credit plus $20 referral credit) $5.00 will be left over for the 5th month.
Option 2 (3 Months 82GB) - Activate on the $40 40GB per month plan. When the 1st billing date comes you'll get another 40GB. Then switch to the $10 1GB per month plan for the 2nd & remaining months. The first 3 months cost is covered ($40 starter pack credit plus $20 referral credit) and data rolls over every month or can be gifted.
Billing Dates (4th, 12th, 20th & 28th)
Plans are billed on the same date monthly. The time between activation and the next billing date is free.
One month worth of data is credited on activation, and another on your first payment date, 1-8 days later. So you effectively get double data for the first monthly payment at no extra cost. You can then change to a lower rate plan ($10/month) and use the banked data allowance.

Is double data still a thing?
