Singapore eSIM: Prepaid 5G Data Plans

Largely, yes. Singtel reported in July 2022 that its standalone 5G network covered over 95% of Singapore, including more than 1,300 outdoor locations and over 400 in-building and underground sites. Singtel also notes that you need a 5G standalone-compatible phone to get its full 5G experience. If your phone or plan does not support 5G, it will simply use 4G.

Not always by default. Singtel's hi! Tourist page says a SIM registered with a passport only gets data features, and calls and SMS are not included until you enable them at a selected Singtel hi! retailer in Singapore, with your passport. That matters if you were counting on a local number for SMS codes. Keeping your home SIM switched on alongside a data plan means you can still receive texts from your bank and apps.

Johor Bahru is in Malaysia, so once you cross the Causeway your phone moves onto Malaysian networks and a Singapore-only plan stops working. Check that your plan covers Malaysia, or add one, before you leave. LTA expects the RTS Link, a five-minute train from Woodlands North to Bukit Chagar with immigration for both countries at the departure station, to open at the end of 2026.

Yes. Install your eSIM before departure; once you land, simply enable data roaming to connect instantly at the airport.

Most plans allow topping up data or extending validity: supported plans are clearly marked on the plan card and on the product page. You can also purchase a new plan anytime; the QR code is emailed to you within minutes.
