dtac is warning iPhone users over messages from unknown senders that may appear in iMessage. These may contain advertising messages for illegal services such as gambling. In response, the National Broadcasting and Telecommunications Commission (NBTC), Apple and all operators have launched an investigation and preventive measures.
The discussions between NBTC, Apple and all operators will ensure the highest cyber security standards are in place for the protection of consumers. In addition, dtac recommends iPhone users to report spam and block senders in case they receive suspect messages on iMessage as per the following methods:
1.Report spam or junk
iPhone users can report iMessage that look like spam or junk from Message app. If a user receives an iMessage from an unknown sender, a Report Junk link will appear under the message. Tap Report Junk, then tap Delete and Report Junk. iMessage will forward the sender’s information and the message to Apple, as well as delete the message from your device.
2.Block a phone number or contact
Reporting junk doesn’t block the sender from being able to send another message. To do so, go to iMessage, open the conversation, tap the contact at the top of the conversation, then tap the name, phone number or email address, scroll to the bottom of the screen, then tap Block this Caller.
3.Filter iMessages from unknown senders
iPhone users are able to filter iMessages from people who aren’t saved in Contacts. Go to filter iMessages, go to Settings > Messages and turn on Filter Unknown Senders.
dtac also wishes to stress iMessage spam is not sent by mobile carriers.
