Is Singapore eSIM worth it for a layover? +
Yes. Even a 3GB 7-day plan at $6 is more than enough for a 1-3 day Singapore stopover. Changi Airport has full 5G coverage — your eSIM activates on landing. Use it for Grab taxi, Google Maps, and tourist apps without roaming charges.
Does Singapore eSIM work in Malaysia? +
Singapore-only plans don't work in Malaysia. If you plan to cross the Causeway to Johor Bahru or KL, look for a Southeast Asia bundle that includes both Singapore and Malaysia in one plan.
Which Singapore network should I choose? +
Both Singtel and StarHub are excellent. Singtel has slightly better indoor coverage in malls and hawker centres. StarHub is slightly cheaper. For first-time visitors, Singtel is the safe choice.
