1. Singtel still have the traditional prepaid services. The focus is actually 5G.
Top up for 5G+ 250GB at S$15 per month

And Singtel offers free 5G+ SIM Card replacement for Singtel Prepaid customers.

2. M1 prepaid plan: still the traditional prepaid-plan. The top-up is not cheap for data.

M1 Maxx plans probably offer much better value for both number-parking use case (M1 Maxx Base Plan) and regular data use case (S$10 per month 5G plan) than M1 Prepaid Card.
3. The new Starhub (Star) Prepaid Plans are the most confusing one, it has "Prepaid" name but in reality are a post-paid plan (up to 10 lines and not three lines). The main good thing is that is is
5G enabled and with 120 days grace period. Data bundle is not good. My daughter is using it -- Starhub Prepaid S (automatically upgraded to this plan from the existing Starhub Prepaid card), S$10 per month for 80GB. Initially I wanted to port it out but later think it is actually not a bad plan to keep for my daughter (secondary student) as she does not need much data.

For regular data usage and larger data usage than 80GB, then Eight may be better but Eight 5G is at least S$14.80 per month now. Eight 4G at S$8 per month is cheaper but 4G speed is really not that good with Eight 4G.
4. Comparison of Singtel Hi! post-paid plan with Starhub Prepaid Plan (also apost-paid plan even with the "prepaid" name).
If you compare Singtel Hi! S$10 (port-in)/S$12 per month plan, and Starhub Prepaid S at S$10 per month and Prepaid M at S$15 per month plan, the only question is whether it is 5G enable or not. If yes, the S$10 (port-in)/S$12 Singtel Hi plan is kind comparable with Starhub Prepaid M plan but cheaper (better value).
