The Dufresnes

Hong Kong is the most three-dimensional city we've ever tried to navigate. It doesn't just sprawl outward — it stacks. Walkways cross above streets, the Mid-Levels escalators climb the hillside, malls connect through their upper floors, and the MTR runs layers deep beneath all of it. On our trip there, the single most-used thing on our phones wasn't the camera — it was the map. Here's how Holafly handled a city that's genuinely hard to move through, and why unlimited data earns its place here.

Why Hong Kong is a navigation problem (and a data one)

Most cities you navigate on a flat map. Hong Kong you navigate in layers, and that changes everything about how much you lean on your phone:

• The MTR is the backbone, and it's fast, but interchanges are big and multi-level, and getting the right exit out of a station can mean the difference between arriving at your destination and surfacing on the wrong side of a hill.
• Above ground is 3D too — elevated walkways, the Central–Mid-Levels escalator system, and mall-through-routes mean the "walking directions" genuinely matter, not just the direction of travel.
• Kowloon and Hong Kong Island feel like different cities, linked by the MTR and the Star Ferry, and you'll cross between them constantly.
• Everything is dense and vertical, so the restaurant you want is often on the 14th floor of a building with no street presence — you find it by phone or you don't find it.

Add the usual translation (Cantonese menus and signage), Octopus-card top-ups, and real-time transit, and Hong Kong turns out to be one of the more data-dependent cities to visit well.

How Holafly held up

The honest report from our time there: coverage was excellent. Hong Kong is one of the most connected places on earth, and it showed — fast, steady data across Hong Kong Island and Kowloon, and, crucially, working underground on the MTR, so we could check the next interchange and the right exit from the platform rather than after surfacing. On the Star Ferry, up on the Peak, through the layered walkways of Central — it kept up.

It runs on local Hong Kong networks (connecting to whichever is strongest). As anywhere, the far edges and some deep interiors can vary, but for a city trip you're on strong signal essentially the whole time.

One thing to know: Hong Kong is not behind China's firewall

This trips people up. Mainland China blocks Google, WhatsApp, Instagram, and more — but Hong Kong is a Special Administrative Region with an open internet, so all your normal apps (Google Maps, WhatsApp, Instagram, Gmail) work exactly as they do at home. A Hong Kong eSIM needs no VPN.

If your trip also includes mainland China, that's a different situation entirely — there you'll want Holafly's China eSIM with its built-in firewall bypass. We cover that separately in our China eSIM guide. For Hong Kong alone, you don't need any of that.

Holafly Hong Kong pricing with THEDUFRESNES

First move: pull up the MTR route to your hotel — you'll be on it immediately.

What other travelers say

On the forums, Hong Kong visitors consistently report the same: coverage is superb (including underground on the MTR), the open internet means no VPN faff unlike the mainland, and the real value is navigation — a vertical, layered city where the map is running constantly. The relief people mention is landing already connected and heading straight for the Airport Express without hunting for a SIM.

Hong Kong FAQ

Does it work underground on the MTR? Yes — that was one of the standouts. Coverage held on the platforms and trains, so navigation kept working below ground.

Do I need a VPN in Hong Kong? No. Hong Kong has an open internet, so Google, WhatsApp, Instagram, and the rest work normally. A VPN is only a mainland-China concern.

What if I'm also going to mainland China? Use Holafly's China eSIM (built-in firewall bypass) for the mainland — see our China guide. A Hong Kong eSIM won't carry the bypass because Hong Kong doesn't need one.

Can I share my connection? About 1 GB/day tethering on the Hong Kong eSIM; for heavy sharing or a laptop, Plans Unlimited has unlimited hotspot.

How many days should I get? Most Hong Kong trips are short and city-focused — a 3–7 day eSIM ($11.31–$26.13 with the code) fits the typical visit.
