I already have a Trend Micro Account; can I transfer my existing licence over?

You can choose to sign in using your existing Trend Micro Account when purchasing Device Protect. You’ll be given a Trend Micro Security Suite product serial number that entitles you to download the apps on up to 10 compatible devices.



I have multiple services on my account, can I receive 2 months free on each service?

Unfortunately, the 2 months free subscription offer is only redeemable once per customer account. 



Why can’t I see the offer under My Offer? 

If you’ve got a Telstra post-paid mobile and/or internet service and you can’t see the Device Protect bonus offer under My Offer, go to Get help in the My Telstra app.



Where do I get a Trend Micro Suite license/ serial number from? 

After setting up your Trend Micro Account, you’ll be given a Trend Micro Security Suite license serial number that can be found in your Trend Micro Account.




How often is my Device Protect subscription charged?

Device Protect is a month-to-month subscription. You’ll be charged the full month subscription on the same day each month. This date may not necessarily align with your Telstra billing date, it’s the date you purchased the subscription. There’s no pro-rata charge or part-refund. If you cancel, you can continue using the product until the next payment date.



Can I purchase more than one subscription?

To purchase a subscription, you must redeem it against an eligible Telstra post-paid mobile or home broadband service, so if you have more than one eligible service, you may purchase more than one subscription. Each subscription gives you access to Trend Micro Security Suite for up to 10 compatible devices.  It’s important to note that each redemption will generate a new Trend Micro licence and that multiple licences (product serial numbers) can be held under the same Trend Micro account.



Do I get 2 months free subscription if I redeem again on another service? 

No, the 2 months free subscription is only redeemable once per customer account.



Can additional Trend Micro products/support services be added to my Telstra bill?

No, only Device Protect will be included on your Telstra bill. Any additional in-app purchases you make when using Trend Micro Security Suite won’t be added to your Telstra bill or Telstra Cyber Security subscription. You must pay for these directly to Trend Micro.

You’ll still have access to your security apps until the end of your monthly subscription. Before this date you will need to remove any saved data on your apps (such as passwords in the Password Manager app). Learn how to remove saved data and uninstall your applications.



When can I cancel my Device Protect subscription?

Your subscription is paid month- to- month so you can cancel anytime. We suggest cancelling at least 1 day before your monthly subscription renews so you’re not charged for another month.



How do I transfer my Device Protect subscription to another eligible Telstra service?

Cancel your existing service before choosing another eligible Telstra service to redeem your subscription against. You’ll be given a new Trend Micro Security Suite product serial number when you redeem your new subscription. To add this new product serial number to your existing Trend Micro account, sign in with your Trend Micro account details and apply the new product serial number to the devices you want covered.
