Top Hong Kong Prepaid SIM Cards 2015

Visit our newer article as of 3/11/2018: Best 2018 Tourist HK Prepaid SIM cards guideUpdate November 8, 2017: 2017 Top HK SIM Card Guide

Visitors coming to Hong Kong are always asking about the best SIM Cards for their needs. There is no one-size fits all prepaid SIM card, and it really depends on a few factors; primarily:

  • Length of stay
  • Voice calls vs data usage
  • SIM card size (micro vs nano)
  • Roaming needs

Cost is usually not a huge factor as telecommunications is relatively cheap here in HK, and each card is more or less around the same price to remain competitive.

If I had to pick my top three, here are my recommendations:

  • Hong Kong only: China Mobile 4G/3G Data & Voice
  • Greater China (China, HK, Macau, Taiwan): China Unicom Cross Border King Dual-Number
  • HK and other countries (includes roaming): one2free Power Prepaid SIM

All prices and costs in this article are in HKD. Pegged at 7.8 HKD per 1 USD.

China Mobile 4G/3G Data & Voice

I’d say the China Mobile 4G/3G Data & Voice prepaid SIM is the best overall card for use in Hong Kong only, for data and voice usage as the name implies. It’s available in both micro-SIM and nano-SIM sizes, so will fit almost all phones these days.

Local calls are a mere $0.10 per minute and only $0.18 per minute for IDD (overseas calls)

IDD calls to:

  • China, Canada, Singapore, USA (mobile + fixed line;)
  • Malaysia, Taiwan, Japan, Australia, UK, and India (fixed-line.)

For data, there’s a 1 day, 5 day, and 10 day package. The 10 days data is a slower version of 3G, but perfectly acceptable for web surfing, e-mails, etc. Data service is a bargain at $30 HKD for 10 days. That’s only $3 HKD a day.

$80 to buy this card with $78 of stored value. You can purchase it at most convenience stores, China Mobile retail outlets, or at Hong Kong SIM Card.

China Unicom Cross Border King Dual-Number

Plan to visit China, Taiwan, Hong Kong or Macau? The Cross Border King Dual-Number prepaid SIM is the best card for use in the Greater China region, as you can use the same SIM card in each of the aforementioned countries. Only drawback, it only comes in regular-SIM and micro-SIM sizes. Those of you with nano-SIM phones will need to cut the card yourself using scissors or a SIM card cutter. (Just cut all of the excess plastic around the chip.)

Costs to use the Cross Border card are certainly higher than a Hong Kong only prepaid SIM card, but it really gives you the flexibility of roaming without worrying about switching SIM cards & finding local options. It also provides two phone numbers, one mainland China number and one Hong Kong number for others to reach you at.

Voice calls range from $0.45 to $3.00 generally, depending which countries you’re in and calling to. It isn’t very cheap, but a short call here and there won’t break the bank.

Data is available, and a cheaper option over voice if you want to use a messaging app like WeChat or Whatsapp. You don’t get a huge allowance of data, so avoid downloading videos. Generally web surfing and e-mail will be fine. (Keep in mind Google, Instagram, Facebook, amongst others are often blocked in China.)

$120 to buy this card with $120 of stored value. Some convenience stores may carry it, you can purchase at a China Unicom retail store or online at Hong Kong SIM Card as well. (Not as common to find as the other two cards.)

One2Free Power Prepaid SIM

one2free’s Power Prepaid SIM is your best choice if you are visiting Hong Kong and plan to roam as well. You could definitely use this only in Hong Kong as well, but as compared with the China Mobile card, the data fees are slightly higher.

Roaming is available to countries worldwide, not just Asia. Great if you want to do a trip to HK, Thailand, Malaysia, & Singapore, etc; and won’t want to bother getting new SIM cards everywhere. See full list and fees covered.

Local calls are a mere $0.10 per minute and only $0.18 per minute for IDD (overseas calls.) Full list of IDD countries.

Data fees range depending on the length and allotment:

  • Hourly Unlimited: $8
  • Day Pass Unlimited: $28
  • 7 Day Pass Unlimited: $78
  • 30 Day 300 MB: $38
  • 30 Day 1 GB: $88

You’ll get a 30% bonus when you recharge the phone card.

$88 to buy this card with $88 of stored value. You can buy it at most convenience stores, one2free retail outlets, or at Hong Kong SIM Card.


For all of these cards, if you run out of stored-value, you can top-up the value of the card and refill additional money onto the card online or in a store.

These prepaid SIM cards are carried at local convenience stores such as Circle K, 7-11, Vanguard, etc. Availability is hit or miss, sometimes they will be out of stock, especially the airport store. You might need to search a few stores before finding the card you want. Otherwise another option is to use Hong Kong SIM Card and have the card shipped to you so you’ll have it upon arrival.

Hope this article helps you with your prepaid SIM selection during your visit! Let us know your experience with these cards below and if you agree with my view on it.

  • I am traveling to hong kong for 4 days . I need data only for Internet , no need phone call . Which sim card should I get and is it available in all 7-eleven store ?

  • Hi, I am staying in HK for a few months. Usually I don’t make nor receive phone calls. When I do, only talk for less than a minute. Let’s say I talk on the phone for less than 2 minutes per month. In another country, I use 4G of about 3-3.5GB data per month. In HK, I mainly use the internet on the MTR. Which card do you recommend? Thanks.

  • hi looking for sim for when I travel to hk (4 days) and thailand(2 and half weeks)

    do you suggest just getting separate sim cards in each country or sticking with One2Free?

    need 2 sums for 2 people- good data and making emergency calls between them

    Many thanks

  • hi
    travelling to Hong Kong for 3 days and thailand for 2 and half weeks.
    what do you u suggest?
    -One2Free Power Prepaid SIM looks good but we don’t mind getting one for each country if overall it’ll be cheaper

    I need 2 sim cards for 2 travellers where data is important and can make emergency calls to one another
    many thanks

  • hi, I will be travelling to China, Macau, Zhuhai, Guangzhou and Shenzhen, which sim card service is better? I will be using quite a bit of data. Hope you can recommend me.

    • You can try the China Unicom cross border king, but data isn’t that cheap. You might be better finding a local card for mainland china and macau separately if you need a lot of data.

  • Hi, I need a prepaid nano-SIM card for a 30-day period. All I need is voice only, as I plan to use wifi wherever I can. What is the cheapest/best option I can get? Thank you.

  • Strange question from me. I have inherited a HK SIM card and it registers (in HK) to “MORE Mobile” but for the life of me I can’t find out who is the service provider and who I need to recharge with. Any ideas?

  • Hi,very useful article. Thanks.
    Just have a question mark on including Taiwan in the King-Dual-Number deal.
    Since Taiwan is actually not a part of China, politically and Telecom-infrastructure-wise, I wonder if that deal would really work in Taiwan.

  • Hi HK Travel Blog,

    I will be staying in HK for one month and is looking for a prepaid card for voice call, SMS and lots of data at 4G speed without throttling (need to VPN to work during the month, I am guessing 3-5GB per week). Do you have any recommendation for my need?


  • Hey HK Travel Blog,

    I’m staying in Hong Kong for 2 months and need only data, because making calls isn’t needed if using Whatsapp. I hear free wifi is available everywhere in HK, so why do some prepaid cards mention free unlimited wifi? Do I need their specific card in order to access wifi?

    I have researched many websites, but cannot find a good answer. The China mobile states that the 10 day data add on can not be subscribed more than once, so that is not an option for me. The website for One2Free has been changed to CSL, and I cannot find the prepaid card listed on the website.

    What do you recommend for my situation?

    Your advice would be greatly appreciated! Cheers from Canada.

  • Hi, I will be HK for 3 weeks or so in December, I would like to know which one is best? I might travel to Macau or mainland.

    Local & IDD Phone, text & data.

  • Hello,
    I’m looking for a no contract plan or sim card with a sufficient amount of data that I can use in HK for around 2 months. I will be there from end of May to end of July. I saw that China Mobile has a 10-day data package for $30HKD and I’m wondering if there is one for a month? Overall, which one of the above would you recommend?
