Best Tourist HK Prepaid SIM Cards Guide

May 29, 2019: We’ve updated our picks with the 2019-2020 version, please click through here for the latest SIM Cards.

Time for our 2018 edition of Hong Kong’s best prepaid SIM cards! This list is updated to include new products in the SIM card space, and we’ve removed some products which are discontinued. (We still have our 2017 picks if you want to take a look.)

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.

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.

Many cards are marketed for roaming however, such as the China Mobile 4G/3G Roaming card mentioned earlier. Calling rates for these cards are generally less than others. For example, this card is $1.9/min in China, vs $6-8/min for many others.


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, many 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 HK SIM Card; 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!

  • Hi, I will be in Hong Kong and Mainland China (Guangzhou and Shenzhen) between Dec 1, 2018 and Mar 31, 2019. I would need a SIM-card which would give me data (4GB/Month) and calling (free or cheap) to Hong Kong and Europe (mostly Germany and UK). Furthermore I would need an Hong Kong phone number. Is there any card which fulfills these specific needs? Thanks

  • The Discover HK 8 day sim comes with $48 value which you can use to top up another 5 days with 1.5 GB data and unlimited call/sms. So you could potentially use it for a total of 13 days, or if you return to HK within the expiration date, top up 5 days at that time and potentially use the sim on 2 trips.

  • Hi I have question regarding international incoming, is that also chargeable and also local incoming calls are charged too?

    I heard something like this from a friend.

  • Hey, I’ve got a question and I hope you can help me. I’ve got the “4G/3G Data & Voice Prepaid SIM Card by China Mobile” the $78 one. I bought it at 7-Eleven.

    How do I refill it? I tried through the app, which is asking for a phone number, and as far as I know, this one doesn’t have a phone number. On the Settings of my phone (Android), it says “Phone number not available.” I tried through the 7-Eleven, but they told me that my only option was to buy a new card.

    I will be in Hong Kong for about thirty more days.

  • Thank you for your useful information! I will be in Hong Kong for 6 weeks early next year. For what I read in your bolg 4G/3G Data & Voice Roaming: China Mobile card 30 day data plan would be the best fit for me. I would like to know if I could get a prepaid mobile WiFi in HK for my apartment there? if so , which one would you recommend? Thank you for your help!
