Traveling to Hong Kong soon and planning your trip? Make sure to get a local prepaid sim card in Hong Kong to stay connected. It is the cheapest way to have a data connection on your phone with the fastest internet speed. Buying a sim card in Hong Kong is easy and only takes a couple minutes.

This is your complete guide for buying a sim card in Hong Kong with where to buy a sim card, the best 4G/5G network, up to date prices as per June 2022, my recommendation and even info about international and e-sim cards for Hong Kong.

Hong Kong is a breathtakingly beautiful bustling metropole that is home to some amazing tourist attractions and fantastic nature trails, lively traditions, unique cuisine and a melt pot of many different cultures. I recently had to change to visit Hong Kong for the 4th time as it is one of my favorite cities in Asia.

As part of traveling to every country in the world I get to some really cool places. Everywhere I go I write local guides for buying a prepaid sim card to help travelers save money on high roaming charges. In total I wrote more than 150 guides from around the world: Thailand, Vietnam, USA, Mexico, Turkey, Europe, Turkey, Dubai, South Africa, Paris, Rome, London and many more.

Why buying a local sim card in Hong Kong?

Do yourself a favor and stay connected while traveling. It makes everything so much easier. Think about ordering a taxi through an app, get directions from Google Maps or find nearby local restaurants with good reviews.

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? And WiFi? Yes, there is free WiFi almost everywhere in Hong Kong but did you know that roaming the internet on a public WiFi is through an UNSECURED connection. If using public WiFi the use of a VPN is recommended.

Getting yourself a local prepaid sim card for Hong Kong is not only done easy and fast it also guarantees you the fastest internet connection and the best 5G network coverage.

My recommendation

Traveltomtom recommends a SmarTone prepaid sim card for Hong Kong for short visits. SmarTone give you unlimited data per day for 24 HK$ that is $3 per day. So when visiting Hong Kong for just 3 days you can be sorted with unlimited data for less than $10 USD.

If swapping sim cards and changing phone numbers does not have your preference then you might want to look into getting a portable WiFi device for traveling. Personally I am not a fan, read about it in my article ‘How to get WiFi when Traveling’. Another option is an e-sim card for Hong Kong, which can already give you 5 GB data for $13. Click on the link for more info.

The cheapest way to get connected is a local prepaid sim card. But another great option is a world travel sim card. Check out my comparison of the best international sim cards in 2022 and find some great sim card deals for traveling in Hong Kong.

However, the easiest way to stay connected when traveling in 2022 is an e-sim card.

Where to buy a sim card in Hong Kong

Hong Kong Airport

The best and easiest way to get connected is to buy a local sim card on arrival at Hong Kong Airport. There are multiple stores that sell sim cards for tourists at Hong Kong Airport.

In Arrival Hall A you can find a store called SongWiFi that sells prepaid sim cards. But you can also buy them at 7-Eleven, which is located in the middle of the Arrival Hall. There is also a China Mobile store and at Circle-K they also sell prepaid sim cards for Hong Kong, just like a store called 1010 with a big yellow sign. All these stores are all located on L5 in the arrival hall.

There is free WiFi available at Hong Kong Airport for your convenience.

Hong Kong Malls - Official provider retail stores

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 the by you preferred provider on Google Maps and go to the nearest store.

Convenience stores

Traveltomtom does not recommend you to buy a sim card from the 7-Eleven or any other of the convenience stores. Why not? These employees are not specialized in selling sim card. 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.

Order a sim card for Hong Kong online

When you want to get connected as soon as you land then you can order a Hong Kong sim card online and get it shipped to your home address before your trip. You can already find Hong Kong sim cards for $20 with 6 GB data. Click on the link to find out more.

Registration process

Nowadays just like in every other country you will need your passport to buy a sim card in Hong Kong. But this only recently changed. Before March 2022 you could buy a prepaid sim card without any form of identification. Your Hong Kong sim card will be registered on your name and passport number. If you want to avoid this you can opt for an international sim card or an e-sim card.

Internet censorship in Hong Kong

In huge contrast with China mainland there is no internet censorship in Hong Kong. All social media apps work like normal so there is no direct use for a VPN. However, for safety and privacy reasons it is still recommended.

Mobile internet providers in Hong Kong

There are 4 mobile internet operators in Hong Kong that sell prepaid sim cards:

  • 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.

Best 4G/5G network in Hong Kong in 2022

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.

4g 5g network china mobile hong kong

4G/5G network CSL

4g 5g network csl

4G/5G network Smartone

4g 5g network smartone hong kong

As you can see from the above Hong Kong mobile internet coverage maps all tourist destinations and places to visit in Hong Kong are very well covered with either a 4G and mostly even a 5G signal.

However, we can also clearly conclude that Smartone has the best 4G/5G mobile network in Hong Kong and that the China Mobile and the Three network are a little less advanced.

Sadly and pretty remarkable, CMHK is the only operator that offers a prepaid 5G sim card for Hong Kong.

Prices prepaid sim cards in Hong Kong in 2022

All prices below are in HK dollar. 100 HK$ is worth around $13 USD.


china mobile prepaid sim card hong kong

A CMHK prepaid sim card costs HK$ 68 and comes with 18 HK$ credit. Although, 2 HK$ credit is taken for the registration process and it is a monthly occurring fee.

This CMHK tourist sim card comes with 3 GB data for 5 days. The 16 HK$ remaining credit/airtime can be used to call any number around Hong Kong and mainland China for 0,25 HK$ per minute.

After you finished the 3 GB data you can top up with the following 4G data packages:

  • 18 HK$ = 1 GB valid for 1 day
  • 38 HK$ = 2 GB valid for 3 days
  • 48 HK$ = 3 GB valid for 5 days
  • 40 HK$ = 2 GB valid for 30 days
  • 88 HK$ = 3 GB valid for 30 days

Click here to find the latest China Mobile Hong Kong prepaid sim card and top up deals.

All the CMHK data packages as well as the starter package claim to come with unlimited internet, but THIS IS USELESS. After you used the data from your package, the internet speed will be reduced to 384Kbps. Meaning just enough for WhatsApp, basically an E signal.

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.

The data packages are rather small, I had hoped to see bigger data packages as with streaming videos and uploading Instagram videos, etc. the usage of data can go fast. Also these are 4G sim cards and why use 4G when there is 5G available.

china mobile 5g prepaid sim card hong kong

So I search around and also found a prepaid 5G sim card of CMHK on their website:

  • 48 HK$ = 3 GB valid for 90 days.

This lets you roam the internet on the fastest speed possible and no contract is needed. Whenever you used the 3 GB data you simply top up again. When buying a CMHK sim card for Hong Kong this would be my recommendation.

The CMHK 5G sim card can only be bought from an official CMHK retail store or from a 7-Eleven.


csl prepaid sim card hong kong

They offer 2 different CSL. plug and play Discover Hong Kong Tourist SIM Cards, one for 8 days and one for 5 days and include unlimited calling time in Hong Kong.

  • 88 HK$ = 3 GB data for 5 days
  • 118 HK$ = 8 GB data for 8 days

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:

  • 48 HK$ = 3 GB data + unlimited calls

For the latest CSL. prepaid sim card deals have a look at their website in the link.

All the above CSL. prepaid sim cards are sold in the official CSL. retail stores around Hong Kong as well as in 7-Eleven, Circle K ,Vango Convenience Stores and the 1010 mobile shop at Hong Kong International Airport in the arrival hall level 5.

Unfortunately CSL. does not offer a 5G prepaid sim card for Hong Kong, only monthly plans. So if you are a tourist visiting Hong Kong and you want to roam on 5G then a CSL. sim card is not your thing.

Three - 3 Hong Kong

3 prepaid sim card hong kong

A prepaid 3 Hong Kong All-In-One sim card costs 88 HK$ and comes with 88 HK$ credit. Basically a Three sim card for Hong Kong is free. You can use this credit the way you want to.

Calling costs: 0.1 HK$ per minute and you can buy one of the following data packages:

  • 18 HK$ = 1.5 GB for 1 day

  • 68 HK$ = 4 GB for 7 days
  • 88 HK$ = 5 GB for 14 days

There is also a 3 Hong Kong prepaid sim card deal for HK$ 138, which basically means you have HK$ 138 credit instead of HK$ 88.

For the latest Three prepaid sim card deals for Hong Kong click on the link to go to their website.

Unfortunately Three Hong Kong does NOT offer a 5G prepaid sim card for tourists either, just like CSL.

The All-in-one Three sim cards are available self-service kiosks (Live Box) or in authorized 3 Hong Kong stores. You can also purchase Three Hong Kong sim cards at the airport in the 7-Eleven.

For this last sim card deal there are data packs you can activate:

  • 38 HK$ = 2 GB for 3 days
