Why Singapore is different
"Singapore's 5G covers 100% of the landmass — but local tourist SIMs cost S$15 minimum and take 15 minutes of ID checks. A 1 GB eSIM covers a full layover for under $3."
Singapore is the only major country with effectively 100% 5G coverage. Changi Airport is the most-awarded airport on the planet, and it's the transit hub for South-East Asia and Oceania. For travellers with 6–24 hours on the ground between flights, an eSIM is the difference between "expensive airport Wi-Fi" and "Sentosa beach for the afternoon".
Our Singapore plans run on Singtel, which has marginally better Jurong and Changi coverage than StarHub. StarHub is the fallback for central business district 5G density.
Coverage you can actually measure.
We run Singapore on 2 carriers so your profile falls back automatically if one signal drops. Coverage figures are measured against our own uptime data, not carrier marketing claims.

Troubleshooting
- Singapore has no meaningful dead zones. If you see "No service" anywhere on the island, toggle airplane mode — it's a device issue, not a network issue.
- The MRT underground has full coverage on every line.
- Some Johor Bahru (Malaysia) border areas are close enough that your phone may accidentally register on a Malaysian carrier. Set Network Selection to manual → Singtel.
