There is a risk that non-scam messages will be blocked and also that scam messages may not be correctly blocked. Please note that our upstream provider accept no liability where an SMS message that is a scam is not blocked.

Telstra’s SMS Filter capability:


i. May inspect the content and metadata of SMS messages which are intended to be received by the end user, including text, time, sender, number of messages sent, and recipient (“SMS content”);


ii. May use the SMS content to detect if an SMS message is scam; and


iii. Where an SMS message is identified as scam, may block that message before it reaches the intended recipient’s mobile phone (and any blocked messages will not be retrievable).

The filter involves network systems scanning the SMS messages and if and when a message is identified as being a scam, the message will then be blocked by the network. The result is that the message would not be sent to the you and would not be retrievable.

In effort to combat the rising number of scams targeted at consumers via SMS, Telstra have turned on a brand-new feature to find and block SMS scam messages with suspicious links as they travel across the Telstra Mobile Network, to stop many of them before they reach your mobile device.

This involves deploying capabilities to detect and block SMS messages identified as scam and stopping
the message before they reach the end user. This will reduce the volume of scam messages that are sent to those on the Telstra Mobile Network using SMS.

Yes, you can opt-out of this filter any time. To opt-out of the blocking action, the you must send an SMS message “FILTER OFF” to the number 0438 214 682

Short Messaging Service (SMS) technology is being used by criminal actors to deliver attempts to scam Australians. This filter is in place to protect you from scam messages with the use of capabilities that will block scam messages before it reaches you.

If an SMS has been blocked, this means that the intended recipient will not receive the SMS and the blocked message cannot be retrieved.

The purpose of this initiative is to reduce the volume of scam messages that are sent to end users on the Telstra Mobile Network using SMS. It is not guaranteed to stop all scam messages.

You will not receive the Referral Credit if your friend cancels their mobile plan before they pay their first bill.

There could be a few reasons why this might happen, depending on whether you were the referrer or the referred person.

  1. If you did not enter a valid mobile number during your order, then the person who referred you will not receive their credit.
  2. If you used a promotional code or took up a special offer when you placed your order, you will not receive a Referral Credit when you activate your SIM, we will however still apply a credit to your friends Account when you pay your first bill.
  3. If you referred someone to Pennytel and they activated their SIM card but have not yet paid their bill, you will not receive your credit until that has happened.

If you have referred someone to Pennytel, you will receive your Referral Credit after your friend has signed up and paid their first monthly bill. Your Referral Credit will show on your next bill.
