My recommendation
Traveltomtom recommends a CMHK prepaid sim card for Hong Kong or when buying a sim card at Hong Kong Airport then get a China Mobile tourist sim card with 80 GB data for around $11 USD.
But... do you want to deal with Internet Censorship of Hong Kong?
All prepaid sim cards you buy in Hong Kong come with a long registration process (can take up to 24 hours) and with internet censorship. For example TikTok is blocked on Hong Kong prepaid sim cards.
To avoided all this hassle simply order an eSIM for Hong Kong on the internet and there is no internet censorship on eSIMs for Hong Kong. A Hong Kong eSIM from SimOptions gives you 10 GB data for $12.90 USD.

Why buying a sim card for Hong Kong?
Do yourself a favor and stay connected while traveling to Hong Kong. Trust me it makes everything so much easier and more fun. Think about ordering a taxi through an app, getting directions from Google Maps or find nearby local restaurants with good reviews, finding your nearby friends, checking your online banking apps, emergencies, etc.
Overseas data plans? Did you know that they limit the internet speed? Can you still roam on a 3G connection or do you want 5G? There is 5G everywhere in HongKong.
And what about WiFi in Hong Kong? Yes, there is free public WiFi almost everywhere in Hong Kong but did you know that roaming the internet on public WiFi is through an UNSECURED connection. That means your data is not protected. If using public WiFi the use of a VPN is recommended to protect your data.
Staying connected in Hong Kong is easy and does not need to cost a lot of money. There are amazing eSIM deals for Hong Kong and if you want to buy a local prepaid sim card in Hong Kong it is also done easy and fast.
Being a full time travel blogger and nomad since 2012 I constantly get to new countries and in every country I look for the best ways to stay connected. As I am also on a journey to travel to every country in the world I get to some really cool places.
Everywhere I go I write sim card guides for tourists to help them save money on high roaming charges. In total I wrote more than 200 guides from around the world: Thailand, Bangkok, Indonesia, Bali, Singapore, Vietnam, USA, Mexico, Turkey, Europe, Dubai, South Africa, Paris, Rome, London and many more.

Where to buy a sim card in Hong Kong
Hong Kong Airport
The easiest way to get connected when arriving in Hong Kong is to buy a prepaid sim card at Hong Kong Airport. There are multiple sim card shops that sell sim cards for tourists at Hong Kong Airport.
There are several 7-Eleven convenience stores as well as Global Exchange shops that sell prepaid sim cards for tourists. There is a 7-Eleven already before you go through customs.
When you arrive in the Arrival Hall there is also a China Mobile and a 1010 sim card store. All these sim card stores are all located on L5 in the middle of the arrival hall. There is free WiFi available at Hong Kong Airport for your convenience.
Buying a sim card at Hong Kong Airport is very convenient, but expect to pay tourist prices compared to the sim card plans you can find in the city center of Hong Kong. But if you do a little effort you can find a sim card plan with 30 GB data for around $12 USD.
Keep in mind that at Hong kong International Airport they do not sell eSIMs. They only sell physical prepaid sim cards for tourists.
They have a great prepaid sim card offer at the Global Exchange stores. They set up the sim card for you, you give them your passport, they do the registration for you and you get this amazing tourist sim card deal.
- 80 GB data + 1,000 minutes = $88 HKD - $11 USD
You can only buy this physical prepaid sim card in person at the airport, not on the internet. Apart from the fact that it comes with the internet censorship in Hong Kong, TikTok is blocked on this sim card for example, this is of course one of the best Hong Kong prepaid sim card deals for when visiting Hong Kong in 2025.
Retail stores mobile internet providers
If for some reason you were not able to buy a sim card on arrival at the airport then I recommend you to go to any of the official mobile internet provider stores in any of the malls. There are so many around. Just type in your preferred provider on Google Maps and go to the nearest store.
Convenience stores
Traveltomtom does NOT directly recommend buying a sim card from a 7-Eleven or any other of the convenience stores in Hong Kong. Why not? These employees are not specialized in selling sim card and most important you will have to do the activation all by yourself. In an official retail store they do everything for you AND they make sure it works before you walk out of the store.
The sim card registration process in Hong Kong is pretty complicated if you have to do it yourself. You will have to register online, scan your passport, provide all the details and then send it for approval and wait. In some cases people have reported to wait for up to 24 hours to get approved.
Order a sim card for Hong Kong online
To avoid all the hassle of buying a prepaid sim card in Hong Kong on arrival you can also order one on the internet. You are connected as soon as you land in Hong Kong.
SimOptions has international prepaid sim cards that will be delivered to your home address before your trip. You can already find Hong Kong prepaid sim cards for $24.90 USD with 10 GB data.
However, the most convenient way to get internet on your phone when traveling to Hong Kong in 2025 is an eSIM. Order your eSIM for Hong Kong directly online.

Mobile internet providers in Hong Kong
There are 4 mobile internet operators in Hong Kong that sell prepaid sim cards for tourist:
- CSL - Hong Kong Telecom
- China Mobile Hong Kong - CMHK
- Smartone
- Three - 3
All of them have excellent network coverage throughout Hong Kong and its outlining areas and islands.
Registration process
Just like in most countries you will need your passport to buy a sim card in Hong Kong. Before March 2022 you could buy a prepaid sim card without any form of identification, but things changed and a copy of your passport will be taken in the phone store when you buy a prepaid sim card. Your Hong Kong sim card will be registered on your name and passport number and you get a sim card with a Hong Kong phone number starting with +852.
If you buy a prepaid sim card in a convenience store you will have to do the sim card registration yourself and it is a 6 step verification process and you will need to wait for it to be approved which can take up to 24 hours.
To avoid the registration you can opt for an international sim card or order an eSIM for Hong Kong online, they only require your email address.
Internet censorship in Hong Kong
In huge contrast with China mainland there is much less internet censorship in Hong Kong. Most social media apps work like normal, the biggest exception is that TikTok is blocked in Hong Kong and you will need a VPN to use TikTok. All other social media apps like Facebook, Instagram, Snapchat, Youtube, WhatApp work like normal.
Google Maps, Safari, Google Chrome all work without any issues, but you will see that many webpages are blocked.
Best 4G/5G network in Hong Kong in 2025
Hong Kong is one of the most advanced countries when it comes to 5G mobile internet. Almost all of the country and especially the tourist attraction in Hong Kong are covered with a 5G signal and that is not limited to 1 or 2 providers, but all of them.
I will show you the 4G/5G network coverage maps and you will understand what I mean.
3 Hong Kong 4G/5G network coverage map
CMHK 4G/5G network coverage map
CSL 4G/5G network coverage map
Smartone 4G/5G network coverage map
As you can see from the above Hong Kong mobile internet coverage maps all tourist destinations and best places to visit in Hong Kong are very well covered with a 4G/LTE/5G signal. In fact there is pretty much 5G everywhere in Hong Kong.
We can also clearly conclude that 3 Hong Kong and China Mobile have a much smaller mobile data network compared to CSL and Smartone. Smartone has the best 4G/5G mobile network in Hong Kong in 2025.
The big bummer is that Smartone, CSL and Three Hong Kong do not let prepaid sim cards use the 5G network. Only China Mobile allows its prepaid costumers to use the 5G network.
Prices prepaid sim cards in Hong Kong in 2025
All prices and info below is update per January 2025. Prices are in Hong Kong Dollar and 100 HKD = $12.8 USD and $1 USD = 7.8 HKD.

The CMHK sim card package will say unlimited data, but don't be fooled. After 7 GB data on max speed the internet speed will be reduced to 384 Kbps, which is barely enough for using WhatsApp.
All the above CMHK prepaid sim cards are sold in the official CMHK retail stores around Hong Kong as well as in 7-Eleven, Circle K and Vango Convenience Stores. If buying a CMHK prepaid sim card Traveltomtom advices to visit one of the CMHK stores where they will instantly activate your prepaid sim card on your passport.

CSL.
At CSL. offer 2 different plug and play Discover Hong Kong Tourist SIM Cards. One for 8 days and one for 5 days and both prepaid sim card plans include unlimited calling time in Hong Kong.

Data is valid in Hong Kong AND Macau! So this is a great sim card if you are visiting Hong Kong and Macau in the same trip. These sim cards also include free CSL. WiFi service wherever you can find a CSL. WiFi signal in Hong Kong.
If you finish the data of your starter package, CSL. Offers the following data top up package:

Best sim card for Hong Kong in 2025
The cheapest way to get data on your phone when traveling to Hong Kong is buying a local prepaid sim card at Hong Kong Airport.
China Mobile has a great prepaid sim card deal at the airport for around $11 USD you get 80 GB data. In the city center in China Mobile stores you only get 7 GB data for $10 USD. So pick your favorite.
A much faster way to get connected is an eSIM and the best things about eSIMs for Hong Kong is that you avoid the internet censorship!
Therefore my first recommendation is to get yourself an eSIM and you are online as soon as the plane lands.
A Hong Kong eSIM from SimOptions gives you 10 GB data for $12.90 USD. Check out my comparison of the best eSIMs for Hong Kong in 2025.
After comparing all the prepaid sim cards for tourists the conclusion is that China Mobile is the only provider that offers 5G on tourist sim cards. CSL, Smartone and Three only offer 4G/LTE on prepaid sim cards for tourists.
If you decide to buy a sim card on arrival in Hong Kong then be aware that you can only get a physical prepaid sim card, eSIMs for tourists are not available.
Keep in mind that with a China Mobile prepaid sim card you will experience internet censorship and for example Tiktok is blocked.
Also keep in mind that if you are traveling to mainland China or Macau roaming charges may apply. However, some prepaid sim card plans offer free roaming in Macau and/or mainland China.

Uber is officially illegal, but still widely used. An Uber ride from the airport to the city can easily cost you around $40 USD.
