singtel always like that..
3G shut down, M1 and starhub finished 30 Nov 2024. Singtel just finished in late 2025
1) M1 shut down 3G on 31 July 2024.

Yes, it’s time for 3G to power down and take its final bow on
31 July 2024, paving the way for True 5G network high-speed connectivity.
I only got one M1 Prepaid SIM Card in late 2025 so not affected by 4G or 5G SA migration. It is already 5G enabled and I can get 5G SA.
2) StarHub shut down 3G from 1 Nov 2024. Take note the "from" word. Not so sure they really shut it down on that date. Need confirmation.
I exchanged three StarHub Happy Prepaid 3G SIM Card after that date cause I noticed no signal from one of the phones. But I forgot the exact date I went to StarHub Jurong Point Shop to exchange the three StarHub Happy Prepaid Cards, probably early 2025. They changed the cards directly to 5G SIM Cards. So now we can get 5G SA after the migration to the new StarHub Prepaid S plan (5G plan).

We're switching off our
3G network from November 2024
3) Singtel is saying that 3G network is closing from 1 Nov 2024. Take note the "from" word.
But you are right some users may have access to SingTel 3G until late 2025, based on your testing.
Our two SingTel postpaid SIMs are 4G enabled so they are not affected by 3G shutdown. But I changed them to 5G+ SIM Card in 2024 using SingTel Shop Kiosk.
Then I totally forgot that we still had one old 3G MicroSIM which came with the Fibre Broadband subscription back in Feb 2012. It is actually classified as a postpaid as per IMDA classification. Anyway I got the card exchanged to 5G+ SIM in 2025 with the help of SingTel Jurong Point Shop staff.
Our SingTel prepaid card is also 4G ready. I exchanged it to the new 5G+ SIM Card late 2025 at a SingTel roadshow.
