(If you’re looking to see what we selected last year, you’re welcome to visit our best Hong Kong SIM cards for 2018)

The SIM card landscape has changed the last few years. For 2019 there’s a lot more data options, higher allowances (e.g. more gigabytes), and less roaming charges. All positives for the consumer!

Also, 3-in-1 SIM cards are now norm. You do not need to specify micro/nano sizes. The SIM card will look like this, and you pop out the size that fits your phone, super easy.

This guide gives you everything you need to know about prepaid SIM cards in Hong Kong, and some popular options. (This guide is applicable for many other Asian countries. However, some countries such as China and Singapore require identification before purchase, Hong Kong does not.)

Quick primer on voice, SMS, and data:

Voice is straightforward, phone calls are rounded to the nearest minute, and charged at a set price per minute. Simply guesstimate how many minutes you’ll call using the prepaid SIM to figure out how much credit you may use. (You don’t need voice minutes to call someone. You can download and use one of the following apps which will utilize your data allowance WhatsApp, WeChat, Facetime, Skype, Line, etc.)

SMS (aka text message) is not free to send in Asia. It’s very cheap to SMS others on the same mobile network, and slightly costlier out of network. However, receiving incoming SMS to a HK number is free, anywhere worldwide. Our suggestion is not to use SMS. As with voice, use a messaging service such as iMessage, Facebook Messenger, Skype, WeChat, or Whatsapp to chat with your friends and family. Messaging programs use data only, and you can reach all your friends overseas.

Data is usually what travelers covet these days. 4G is readily available in Hong Kong and throughout Asia, and 5G is rolling out now too. Most of the prepaid services will either offer 4G or 3G, which are both still plenty fast. As long as you aren’t downloading huge files or videos, you should be fine.

On many SIM cards, you will need to enter a code from the packaging to activate the particular data package you would like. It is easy to do, don’t fret. Considering turning off apps refreshing in the background to conserve your data usage, and turn off data roaming to avoid fees if applicable.

Activating SIM cards are fairly easy too. Used to be you had to type a code but nowadays you pretty much just insert and start using.

Asia 8 Days Data SIM (unlimited data) by China Unicom

Highly recommended due to very reasonable price and large coverage of countries to roam in. 2GB of high-speed data, and slows down after, but still plenty fast to access anything pretty much except video streaming.

Included free roaming in all of the below countries:

Hong Kong, Macau, Taiwan, Japan, South Korea, Singapore, Myanmar, Thailand, Malaysia, Indonesia, Philippines, Cambodia, Vietnam, & Laos: 8 days or less

Once your total data usage in above listed Asian regions reaches 2GB “Fair Usage level”, the upload/download speed would be reduced and restricted (but not below 256kbps) and tethering and Peer-to-Peer services would not be available.)


If you will roaming with a prepaid SIM, be sure to look at the rates before you use it. Also, double check the card for roaming support, some cards don’t work outside their home country, though many do.

Roamers should pick one of the cards under the roaming SIM section we recommend above to avoid any unwanted surprises. The roaming data cards with unlimited allowance is a huge bonus and you don’t need to worry about running out of money or data on your SIM. Just make sure you turn on the roaming data option on your phone, otherwise it probably won’t work when you arrive in a new country.


Activation for most cards is easy, pop it into your SIM card it should register automatically. Some may require a number combination to be sent, be sure to read the instructions. Keep in mind many of the cards must be activated in Hong Kong, or some cases activation can be done other countries that are supported, such as China.

Refill / Top-off:

If you used up the credit that was initially loaded onto the card, some cards allow refills or “top-up.” This can be done online or in-store. It will usually extend the validity of the card as well. For instance, some cards are valid for up to 180 days, then each top-up will extend it another 180 days from the refill date.

How to purchase

There’s a few options.

Online: Purchase from our partner; they will mail the prepaid SIM cards to your door so that you have it for your trip before you leave. Best if you instantly want to turn on your phone once the plane lands in HKG and use it. Saves time for searching for your card or encountering stock issues at the store. They carry cards for other countries as well.

Airport: 7-11 and Circle K are some of the stores which carry prepaid SIM cards. The inventory and stock changes so often it’s hard to know what they’ll have before you arrive. Pro, you can get it at the airport. Con, airport stores are often out of stock on many SIM cards due to the sheer number of passengers.

In-town: Again check out any convenience store, or go visit your local mobile phone store and see what they carry. Major mobile carriers are CSL, Smartone, China Unicom, Three, and China Mobile. Usually you’re limited to whatever mobile brand store you enter but their stock tends to be better than the convenience stores. The customer service is usually better too, helping you activate the SIM card and help answer any questions.

Phone Compatibility

Most important, make sure your cell/mobile phone is GSM capable and accepts SIM cards. (Hint: if it accepts SIM cards, it’s GSM.) Make sure it’s unlocked. Phones in many western countries are locked to only accept SIM cards for one particular carrier, if it’s unlocked you can use it anywhere globally. Call you carrier if you’re not sure, sometimes they can send you a code to enter on the phone to unlock it.

Reminder to bring a paper clip, or needle to put the SIM card tray out if you’re phone has this. Often people forget to bring the pin to change SIM cards and are stuck scrambling to find something that’ll fit in the phone’s SIM card tray eject hole.

If you need more details check which phones will work in Asia. Almost any unlocked phone less than 10 years old that supports a SIM card will work.


Obtaining a prepaid SIM card should not be a stressful event, but many times is it. Hopefully this guide will help. If you run out of funds on the card, you can usually “top-off”, aka refill, your SIM card by adding extra money in-store or online. Read the instructions that come with the SIM card packaging and you’ll be fine. Enjoy your trip!
