Looks like a glitch then. Indeed even the old S$8 4G plan and the S$5 Senior 4G plan are entitled for local data rollover.

I am on the $8 Double Eight plan / $8.80 NEW Double Eight plan - what happens to my plan?
You can continue recharging on your existing legacy plan or switch to our new 5G+ plans. If you have enabled auto-topup (ATU) and have a saved credit card / wallet balance, your plan will renew as usual with no action needed. If you’re interested to enjoy speedier service with 5G+ and more roaming, simply upgrade to our 5G+ Power Plan with 588GB 5G+ speeds at just $10.80/month!
Can new customers switch to eight’s old plans?
No. New customers who sign up from 24 September get to enjoy our NEW 5G+ plans starting from $10.80! It’s the best value 5G+ plan in town.
How much data can I roll over?
There is no expiry date on your data rollover balance, but it is capped at a maximum of 8 months’ worth of your current plan’s entitlements. For example, the Fortune eight plan allows a maximum data bank cap of 5,504GB.
