Frequently asked questions
Yes. Roamis connects through major Singapore networks like Singtel and StarHub, and as a city-state, Marina Bay, Sentosa, Orchard and Changi — essentially everywhere — is covered by dense 4G/5G.
Korean passport holders can enter Singapore visa-free for 90 days for tourism (as of 2026). You must submit the SG Arrival Card online before entry, which is easy with your Roamis eSIM already online. Confirm current rules before you fly.
Validity starts when you install and connect in Singapore — not when you buy. Set it up before you fly and it begins counting from your first connection on arrival.
A Singapore-only plan does not apply once you cross the border. If you’re combining Singapore and Malaysia, choose a Southeast Asia or multi-country plan.
Yes, you can share your connection to a laptop or another device. Heavy tethering may be subject to the fair-use terms shown on the plan.
No. The eSIM runs alongside your existing SIM, so you keep your number for calls and texts while using Roamis for data.
