Which network actually works in Hong Kong
Your best bet for an eSIM in Hong Kong is 3 Hong Kong. They offer solid coverage across the city and most of the outlying islands. While you're unlikely to encounter major dead zones in urban areas, don't expect perfect signal if you're hiking in the more remote country parks.
A 7-day plan with around 8GB of data will set you back roughly $15-$20 USD†. You can often find these plans directly through the 3 Hong Kong website or via third-party eSIM providers like Airalo or Holafly. For a 15-day duration with a similar data allowance, expect to pay closer to $25-$30 USD†.
Activating your eSIM usually involves scanning a QR code. Make sure your phone's airplane mode is off when you scan it, and that you're connected to Wi-Fi. If you're using a dual-SIM phone, especially one with a Chinese mainland variant, be mindful of potential network conflicts. Some users report issues with their primary SIM interfering with the eSIM installation. The QR code itself often has a short lifespan, so try to activate it shortly after receiving it.
A specific Hong Kong gotcha: some operators may block or throttle VPN traffic. If you rely on a VPN for privacy or accessing geo-restricted content, test it immediately after activation. If your chosen provider is blocking it, you'll need to switch to another plan or use a different method.
eSIM FAQ for Hong Kong
Will my phone work with a Hong Kong eSIM? Most modern unlocked smartphones (iPhone Xs and newer, Samsung Galaxy S20 and newer, Google Pixel 4 and newer) support eSIM technology. Always check your device's specifications before purchasing.
Can I use my Hong Kong eSIM as a hotspot? Most plans allow personal hotspot usage, but it's always wise to check the specific terms and conditions of your eSIM plan. Some lower-tier plans might restrict tethering.
What happens if I run out of data? You'll typically be throttled to very slow speeds or require a top-up to continue using data. Check your provider's app or website for data top-up options.
Is it cheaper to buy an eSIM before I go or upon arrival? Buying before you fly is generally more convenient and sometimes cheaper, especially with introductory offers from third-party providers. You'll have connectivity the moment you land.

Buy the eSIM, install it, but don’t turn on data until you land. Some plans only start counting from first data use, others from purchase, check before activating.

Your bank’s 2FA codes still arrive on your physical SIM. Don’t pull it out, just disable data on it in settings.
One eSIM per trip, not per country
For multi-country trips, regional plans (Europe, Asia, Global) usually beat buying separate eSIMs per country.
