Q: Can Singtel hi! PostPaid plan users receive roaming incoming SMS when going overseas?
A: Yes, Singtel hi! plan users can receive incoming SMS while roaming overseas, as long as:
• Your Singtel hi! plan is active and roaming is supported in the destination country.
• You have not activated the Barring Service (International Incoming SMS) in the Singtel hi! app (Me → Settings → Barring Service). If this barring is turned on, all international incoming SMS, including overseas OTPs and notifications, will be blocked until you deactivate it.

Then I ask about incoming SMS from Singapore.
Here is the answer from the chatbot.

Q: What if the roaming incoming SMS is from Singapore? Is it the same?
A: Good question, that can be a bit confusing when you are overseas.
If you are roaming overseas on a Singtel hi! plan, you can still receive SMS from Singapore numbers, even if you turn on the Barring Service (International Incoming SMS).
The barring service only blocks SMS from international (non-Singapore) numbers. Local Singapore SMS (including OTPs sent from SG numbers) are not affected.
