Where to buy
Prepaid SIM cards are readily available in HK at the mobile carrier’s stores, or convenience stores such as 7-11, VanGo, or Circle K. You can also purchase SIM cards online at HKsimcard.com which will actually deliver the SIM cards to your home anywhere in the world. The cost is a little higher but it may be worth it to have access to make calls and access data upon arriving. You can also avoid any hassle of finding the SIM cards when you get here.
Identification is not required in HK to purchase a SIM card. Some countries such as Singapore require a copy of your passport.
Hong Kong is on the GSM network and all phones require a SIM card. Most phones sold in the past 5+ years are “world phones.” As long as it supposed one of the bands listed below you’ll be fine.
Phones must be “unlocked.” Many phones sold in Western countries are locked to the local carrier only, be sure to get an unlock code before you reach HK so that you can use it with the local mobile carriers. If you cannot get it unlocked before you arrive, many times you can go to a mobile phone store and pay a nominal fee to unlock it. Perhaps $150-200 HKD.
2G, and 3G are well established and reliable in HK. 4G LTE is new to the HK market and most carriers are now offering services in 4G LTE.
GSM 900, GSM 1800
UMTS 850, UMTS 900, UMTS 2100
LTE 1800, LTE 2300, LTE 2600
SIM cards come in primarily three sizes, be sure to select the correct size upon purchase.
The electrical components are the same in each card. So you could just cut a larger Standard SIM card into a micro or nano SIM. Or a micro-SIM into a nano SIM.
Vice versa, you can also use a smaller SIM card such as a micro-SIM in a standard SIM slot. I have an older phone where I just slide the micro SIM into the standard SIM slot and keep it in place using tape. This won’t work on newer phones where the SIM card “pops” out of the phone and you need the exact size.
Prepaid Card Selection
Here at Hong Kong Travel Blog we regularly review various prepaid SIM cards on the market. You can take a look at the reviews here, or you can also look at the selection on HKsimcard.com. There is no ideal card, each situation is different.
We can make a quick recommendation from the selection at our partner site Hong Kong SIM Card:

Roaming data: China Unicom – Japan, South Korea, Taiwan data only.
Adding value / reloading
The amount of value on most SIM cards can be added using various methods. The easiest is usually adding value online. You can also go to a convenience store or the mobile carrier’s own stores to add value as well. This can be useful if you have used up your credit and want to add value without getting a new SIM card and phone number. Also, it’s good if you decide to add on data or roaming plans and didn’t buy enough credit to begin with.
You can usually extend the validity of the SIM cards upon each recharge as well, usually ny 90 or 180 days.
