This one started today, but I went into my Optus App to get it and there was a 50% off data sim offer that stacked with the $0 Tablet.
Has to be 30gb data plan or above.
So my deal was
$12.50 x 12 Months
Tab A8 64gb 4G
30 GB Data added to my data pool
$150 total cost.
I put the SIM in, after 4 hours still no service, Messaged via the web chat (20 min wait), they activated the SIM.
Got an SMS saying activated (and OPUTS SPORT email too)
I still have PENDING on the OPTUS app, but If I log in via web its all there.
Hopefully the app updates tomorrow or another chat session!
