Which network actually works in Hong Kong
SmarTone is your best bet for reliable eSIM coverage in Hong Kong. Their network is solid pretty much everywhere you'll actually be, including on the MTR and ferries. You might get spotty signal on some of the more remote hiking trails or outer islands, but for city life and standard travel, it's the most consistent.
For a 7-day plan with around 5GB of data, expect to pay between $15 and $20 USD. If you need closer to 10GB for 15 days, bump that up to around $25 to $30 USD. These aren't the cheapest plans in Asia, but you're paying for the convenience and reliable connection.
Getting Your eSIM Fired Up Without the Headache
Activating an eSIM can be a pain if you don't do it right. Don't activate it until you've landed and are through immigration. This is crucial. Once you're ready, put your phone in Airplane Mode. Then, scan the QR code provided by your eSIM vendor. Your phone will prompt you to add a new cellular plan. Follow the on-screen steps, and once that's done, turn Airplane Mode off. It usually takes a minute or two to connect.
A quick warning: if your phone is a dual-SIM model that was originally sold in mainland China, it might have hardware limitations that prevent eSIM use. Double-check your specific model if you bought it there.
The One Big Hong Kong eSIM Gotcha
The main thing to watch out for is that some mobile operators in Hong Kong, particularly the smaller ones or those targeting local residents, might block or throttle personal hotspot usage. SmarTone generally allows it, but it's not guaranteed on every single plan. If you absolutely need to tether your laptop for work, confirm this specifically when buying your plan. Some cheaper tourist plans are notorious for blocking it.
Quick Answers to Your Burning eSIM Questions
Will my eSIM work on the MTR? Yes, SmarTone has excellent coverage within the MTR tunnels and stations. You shouldn't lose signal while commuting.
Can I buy an eSIM at the airport? You can, but prices are usually inflated. It's much better to buy online before you fly. Look for SmarTone or CSL.
How long does the QR code last? Most QR codes are valid for 30 days from purchase, but some can expire sooner. Activate it soon after landing.
Is 5GB enough for a week? If you're mostly using it for navigation, messaging, and occasional social media, 5GB is probably fine. If you stream a lot of video or download large files, you'll want to upgrade to 10GB.

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.
Keep your home SIM for SMS
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.
