Not as good as previous Lycamobile deals, but still pretty good for what you get:
28 day Prepaid SIM Starter Packs: $1 = 1GB; $5 = 8GB; $10 = 30GB
Uses Telstra Wholesale Network.
They will send you a SIM card and you apply the Code they automatically email you, after you pay.
NEVER EVER DEAL WITH LYCAMOBILE. YOU ARE WARNED!
