Korea eSIM

Need assistance at 2 am before a flight from Changi? HelloRoam support is available 24/7. Message us and a real person responds in under 2 minutes. No bots, no hold queue. Whether you need help with eSIM installation, plan changes, or troubleshooting a connection drop, the support team handles it in real time.

HelloRoam connects to local 4G LTE and 5G networks in Korea from the moment you land, at a fraction of what Singtel, StarHub, or M1 charge for international roaming. Plans start from S$4.30 with no lock-in contract and no activation fees. You pay once and use data freely without surprise overage charges.

Keep your Singtel, StarHub, or M1 number active for calls and texts. HelloRoam handles your data through a second eSIM line on any dual SIM compatible handphone. Family and colleagues reach you on the same Singapore number while your travel data runs on a separate prepaid eSIM plan.

HelloRoam connects to 204+ carrier networks across 185+ countries. Fixed data and unlimited data plans available. Your phone switches to the strongest available 4G LTE or 5G signal automatically. That means consistent speeds whether you are in a major city, a highway rest stop, or a rural area.

HelloRoam alerts you at 80% data usage so you are never caught mid-trip without data. Top up instantly from the app without reinstalling your eSIM or visiting a store. Additional data activates in under a minute, keeping your connection live through navigation, video calls, and streaming.

Your South Korea eSIM connects to trusted local 4G LTE and 5G networks. HelloRoam picks the strongest available signal for navigation, streaming, and video calls. You get local network speeds comparable to a prepaid SIM card purchased in-country, without the airport queue.

Travelling to multiple destinations? HelloRoam regional eSIM plans cover Southeast Asia, Europe, the Americas, and 185+ destinations in one purchase. Short holiday or long-term stay: choose fixed data or unlimited data plans. One account, no SIM swaps. A single regional plan replaces the hassle of sourcing a new local SIM card at every border crossing.

Share your Korea eSIM data with a laptop or tablet using your handphone's built-in hotspot. No extra fees, no setup required. Works on all eSIM compatible devices. This is particularly useful for business travellers who need a consistent mobile broadband connection for their work laptop while abroad.
