Telstra's Extra Small data plan is normally $15/month, but connections during '7 Day Frenzy' get $10/month off for the first 12 months.
No lock-in contract, so you can cancel any time and DONT FORGET $45 CASHREWARDS which will equate to $15 for 12 MONTHS , this means $1.25 per month for 5GB data- THIS IS CRAZY!
MOD: Received email from affiliate channel representing Telstra stating that Telstra are currently having tracking issue, and sales through cashback sites such as Cashrewards might not track properly.
Buy it, use it, bank it, boast it, harder better faster stronger!
No excess data charges. When you exceed your allowance, you can continue to access data, but your speed will be capped at 1.5Mbps.
This is a data SIM, so you can use it in devices like tablet, mobile dongles etc. You might be able to use it in a phone, but you can't make calls, it's not made for normal SMS use (charged at PAYG rates).
New customers only. If you want a higher plan instead, $10 discount currently applies those also.
Critical information summary (but does not list the $10/month discount)
Mod: Thanks to Giles for the description, copy pasted from them (who posted the duplicate deal).
