same same, and not different
I guess StarHub Giga may need to have better offering to differentiate with Eight, now that Eight also has 5G offerings.
Previously the differentiation was good since Eight did not have 5G plans.
1) Three tiers from StarHub SIM Only Plans
StarHub Star SIM Only (5G plans only): looks like not many people interested
StarHub Giga (5G and 4G plans)
Eight (5G and 4G plans)
2) Three tiers from SingTel SIM Only Plans
Singtel Gomo and Heya have very good differentiation.
SingTel SIM Only (5G plans only) -- SingTel even got Enhanced and Priority tiers with here. Lower cost plans have 12 months contract, including the S$15.28 per month plan.
Singtel Gomo (5G and 4G plans)
Heya (4G plans only)
