Best eSIM for Hong Kong: land ready for the Airport Express, MTR and Star Ferry.

For travellers who want Hong Kong mobile data on the phone they already own, eSIMbundle is a strong option. Buy a Hong Kong bundle before departure, land at HKG, and use Google Maps, MTR Mobile, Citymapper, Uber and WhatsApp straight away. A VPN is included with every plan.

In Hong Kong, eSIMbundle connects to csl. Your eSIM joins it automatically after landing, so you never need to choose a carrier. csl supports 4G and 5G.

Coverage is generally comfortable across Central, Kowloon, Sha Tin, Tsim Sha Tsui, Mong Kok, Sai Kung and the outlying-island town centres. Signal can weaken in long MTR tunnels, on Lantau country-park hiking trails, in remote Sai Kung Country Park stretches and on ferry crossings to Lamma, Cheung Chau and Peng Chau.

4G is broadly available across Hong Kong and 5G is generally strong across Central, Kowloon and the main urban corridors. Whether your phone connects on 4G or 5G in a specific spot depends on your device, the available partner network and live local conditions.

Light users on Maps and messaging often manage on 1–3 GB a week. Normal travellers using MTR Mobile, streaming, translation and hotel bookings usually want 5–10 GB a week. Heavy video or hotspot users can push past 15 GB a week. Use the Travel Data Calculator to size a Hong Kong plan for your trip.

eSIMbundle Hong Kong plans are data plans. Use mobile data for WhatsApp, FaceTime and other internet-based calling and messaging. Keep your normal SIM active for calls, SMS and verification messages, subject to your home carrier's roaming charges and support.

Yes. On a compatible dual-SIM phone, keep your normal SIM installed and use your eSIMbundle eSIM for mobile data. Your normal phone number stays with your home SIM, and WhatsApp continues using the number already registered to your account.

Yes. In the eSIMbundle app, open Store or Add data and buy a separate bundle on the same installed profile. Each bundle has its own allowance and validity and may wait before first use. Eligible finite bundles offer saved-card auto top-up at 80% used, up to your approved package price. Manage it under Account → Auto top-up; check existing replacement orders before buying again.

Yes. Open the eSIMbundle app → Account → My eSIM → Set up your eSIM and use Install eSIM on this phone, or QR/manual fallback. Confirm the profile appears in phone settings. Installation does not start the bundle; first supported use in coverage does. At your destination, enable the line, select it for data and enable its Data Roaming setting. Keep the profile after the trip.

Yes. Use VPN inside the eSIMbundle app with your normal account. VPN connection requires an active qualifying bundle, including on Wi-Fi. Prepare the app before departure; a bundle awaiting first use may not yet provide access. Choose a country and connect. VPN does not guarantee access to every service.

In town centres on Lamma, Cheung Chau and Peng Chau coverage is generally comfortable. On the ferry crossings themselves and on remote Sai Kung Country Park trails, coverage from any Hong Kong carrier — including your eSIM partner network — can thin out.

Yes. Your eSIMbundle eSIM stays installed on your phone. When you travel to another supported destination, add a bundle for it in your account and it activates on the same eSIM — no new installation required.
