Buy eSIM data plans for Hong Kong
A Hong Kong eSIM is a prepaid mobile-data plan for your trip. Install it on a compatible, carrier-unlocked phone before departure, then select it as your data line within the plan's coverage area.
A Hong Kong eSIM is a data-only plan that loads onto your phone digitally, so there's no plastic SIM to swap. Touch down at Hong Kong International Airport, one of East Asia's busiest gateways, and your line connects to the local 3 HK network with 5G the moment you reach the terminal. Skip the roaming fees and the SIM kiosks: you're online before you clear the arrivals hall. Pull up maps to find your train, message home that you've landed, and check directions across the harbour without hunting for Wi-Fi. Activate it before you fly and arrival is effortless.

Hong Kong
A Hong Kong eSIM keeps you connected as you ride the Victoria Peak tram up for the skyline and wander the harbourfront below.

Frequently asked questions
Which mobile networks does the Hong Kong eSIM use?
Your Hong Kong eSIM connects to the local 3 HK network, including its 5G service where available. You'll fall back to 4G in spots where 5G hasn't reached, so you stay connected across the city either way.
Will I have good coverage across the city and harbour?
In a dense, vertical city like this, coverage is strong across the districts and around the harbour where you'll spend most of your time. It can be more variable in the quieter, outlying areas, so it's worth saving a map offline before any day trips.
Will one Hong Kong plan cover a multi-country trip?
This is a Hong Kong-only plan, made for trips that stay within the territory. If your itinerary crosses into other places, choose a regional eSIM instead so you keep one working line across the whole journey.
When should I set up the eSIM before arriving in Hong Kong?
Install and activate it while you still have Wi-Fi at home or before you board, so it's ready to switch on the instant you reach Hong Kong International Airport. That way you're online walking through arrivals, not waiting in a kiosk queue.
Will the eSIM help me get around on the ferry, metro and trams?
Yes. With data running you can check the Star Ferry crossings, plan MTR metro routes and catch the trams between Hong Kong Island and Kowloon, all with live directions in your hand. It makes moving back and forth across the harbour simple.
Can I keep my own number and use a hotspot in Hong Kong?
Yes. The eSIM runs as a separate data line, so your usual number stays active for calls and texts while it handles your mobile data. Where the selected plan and the device allow it, the connection can also be shared as a hotspot to a laptop or a travelling companion's phone; check the plan details first.
