@AP78, you can update your spend limit through your Optus.com.au/myaccount
Click on the corresponding mobile number under the Your services tab.
Select settings from the menu
Scroll down to Premium SMS Spend control
The default spend limit is $200. Any increase to spend / credit limit will need to be approved by Financial Services. There is a limit per transaction of $29.95, except Google Play, that has a $49.95 per transaction limit.
Spend and credit limits apply to all third party content charged via Premium SMS or Direct Carrier Billing.
Thanks Danc i can understand why they have a capping on the amount per transaction but the amount they have set $30 and $50 really isn't of any use on the gaming side.
Do you know if there are plans to increase these amounts in the foreseeable future maybe like this year? Or rumor has it that they arr planning to ditch the credit thing all together....true??.. thanks for the info
