I just received a sms from Boost stating:
"Get 40GB bonus when you recharge $150 before xx January! Use in Aus in 12 months, bonus applied automatically."
Note: this may also apply to other 365 days plans. received 2 weeks before my next recharge, RECHARGE ONLY, No new SIM purchases
For your reference: Kogan mobile via Vodafone, Catchmobile via Optus and Boost via Telstra.
Damn it! I recharged mine on the 9th of this month. Would have been great had I got the 40GB bonus data.
