Whether you’re heading to Hong Kong for a weekend of skyline selfies, a two-week urban escape, or a full-on extended stay, staying connected is a must. The easiest way? eSIMs. No physical SIM card. No queues at airport kiosks. Just scan a QR code and you're online within minutes.
International eSIM providers like Three UK or Airalo can be preferable to local Hong Kong options like HKmobile if you're planning to visit multiple countries or want a smoother setup process in English. They often offer on-par coverage, easier top-ups, and more user-friendly apps, making them ideal for travellers who want flexibility beyond just Hong Kong.
We’ve rounded up the best-value eSIM plans for Hong Kong right now, organised by trip duration to help you pick what actually suits your itinerary.
Let’s get into it 👇
Because eSIM plans vary by validity period and data allowance, it's worth choosing one that matches your trip length and usage habits—you don’t want to overpay for data you won’t use, or worse, run out halfway through your stay.
Why we love it: If you're in Hong Kong for a week or less, this is hands-down one of the best-value options. 10GB is plenty for using Google Maps, hailing Ubers, scrolling socials, and uploading those iconic skyline shots. It lasts a full 30 days too — so no pressure to use it all in one go. It’s a low-risk, high-reward option for short stays. Want more data? No problem. Smartroam offer a range of plans, all available at Sim Local. You can even download the Sim Local app for quick-and-easy top-ups.
Best Value
Why we love it: Most people visit Hong Kong in 3-5 days, so if you're planning on a longer trip, you might be hoping to fit in some other Asian countries. This plan gives you a generous 18GB and covers 70+ countries, so it’s ideal if you’re planning to hop from Hong Kong to Singapore, Macao, or Vietnam. For just £7 more than Smartroam, you get nearly double the data and regional flexibility. Think of it as your “Asia adventure” pass.
Why we love it: 20GB over 30 days is a sweet spot for many long-stay travellers — enough to work, stream, FaceTime, and browse without stress. While this plan is a bit pricier than others per GB, you can rely on strong city-wide coverage.
Why we love it: If you’re going to be in Hong Kong for a while, this is the kind of set-it-and-forget-it plan you want. No top-ups. No worrying about daily limits. If you're there for the full 90 days, the daily rate works out to around £1.29, which is a solid deal for peace of mind and unlimited(ish) data access.
