Hong Kong visitors can buy local prepaid SIM cards using an accepted passport or travel document and completing real-name registration. SoSIM is a strong budget choice for a longer Hong Kong stay, while CMHK, csl and SmarTone offer useful options with Macau data. Your decision should account for daily limits, regional allowances and whether you need local calls.

Local prices and inclusions checked September 4, 2026. Offers, available card versions and terms may change.
CMHK’s daily allowance suits regular use throughout a trip, while csl’s three-day bundle gives you a total allowance to use across the pass period. SmarTone’s card price and recurring package charge need separate attention, as explained below.
Confirm the complete amount payable for the exact card before purchasing, including any retailer service charge. The table uses published card or visitor-pass prices, rather than assuming that every shop sells every version on identical terms.
If advance setup matters more than a large local allowance, compare Roafly’s Hong Kong data packages alongside these local options. Check that your phone supports eSIM before buying.

Which Local SIM Should You Buy?
SoSIM: a budget choice for a longer Hong Kong stay
The SoSIM local package combines a substantial allowance with local calling, making it worth considering for several weeks in the city. Physical SIM and eSIM versions are available, and both require registration for Hong Kong use.
Keep these conditions in mind:
-
The base package uses 4G and has a 50GB fair-use threshold.
-
Data continues at a much lower advertised speed of 128kbps after that threshold.
-
The local allowance covers Hong Kong; roaming services are purchased separately.
-
The monthly package renews automatically if sufficient prepaid balance remains.
The reduced-speed allowance should not be treated as an unlimited substitute for streaming or large uploads. Also distinguish changing future renewal settings from terminating an active package: early termination forfeits its remaining allowance.
CMHK: daily data for short visits
CMHK’s three- and seven-day tourist cards listed by 7-Eleven give you separate daily allowances for Hong Kong and Macau. Their structure is useful if you want a predictable amount each day.
The seven-day card’s advertised 35GB Hong Kong total is divided into 5GB per day. Do not plan around using that entire amount in or two days. Likewise, the Macau portion is 500MB per day, which needs more care if you will be uploading videos during a day trip.
csl: check the exact Discover Hong Kong version
The three-day Discover Hong Kong pass combines shared regional data with an additional Hong Kong-only allowance. Similarly named three-day csl cards can have different coverage, so match the product name and regional allowance before buying.
Longer csl passes need a closer look. The current csl offer page advertises larger seven- and fifteen-day allowances, but some terms and retailer listings still show smaller quotas. Check the entitlement on the exact card or purchase screen before paying.
SmarTone: shared Hong Kong–Macau data with a recurring charge
SmarTone’s HK–Macau card can suit a visit that extends beyond a short tourist pass. Its package terms separate the HK$78 card purchase from a HK$68 default package charge deducted from stored value.
-
Visitor bonus: eligible visitors registering with a passport or the specified Hong Kong–Macau entry-exit permit receive an additional 7GB Hong Kong–Macau data.
-
Bonus timing: the extra data starts the day after activation and lasts 30 days.
The default charge repeats every 30 days, so review the renewal conditions before adding more credit. Macau data on this product uses CTM, and the phone’s data-roaming setting must be enabled there.
Where to Buy a SIM Card in Hong Kong
Your buying location affects which products you can find and how you complete setup. Decide whether you want an operator shop, a retail purchase or an order before heading out.
-
Operator shops: csl and SmarTone stores are useful places to ask about their current prepaid products and registration process.
-
Convenience stores: 7-Eleven lists CMHK tourist cards and csl products. The Discover Hong Kong range is also distributed through Circle K.
-
PARKnSHOP and Watsons: both sell SoSIM physical cards in Hong Kong.
-
Online order with pickup: SoSIM offers prepaid purchase followed by collection at participating stores; Hung Fook Tong locations are pickup points.
-
Local eSIM purchase: SoSIM also sends an eSIM installation code by email, removing the physical pickup step.
Keep the packaging and receipt until the SIM works. SoSIM purchases from PARKnSHOP or Watsons may require the activation code printed on the receipt.
If you are still deciding between a SIM, roaming or shared connectivity, explore other ways to get in Hong Kong.
Buying at Hong Kong International Airport
Hong Kong International Airport lists 7-Eleven, RELAY and Travelex Worldwide Money among its SIM-purchase options. Buying there can be practical if you want to arrange a physical card before continuing into the city.
Check the exact package, final price and whether staff can help with registration. The airport location alone does not establish a price premium, a particular allowance or included setup assistance.
Passport Registration and Activation
Local prepaid SIMs require real-name registration before you can use the service, including local-operator eSIMs. Registration itself is free; distinguish any optional retailer assistance charge from this requirement.
Under Hong Kong’s SIM registration rules, visitors without a Hong Kong identity card can use an accepted original passport or travel document. HKSAR and British National (Overseas) passports are excluded as identity proof for this process.
What to prepare
Have these ready before starting:
-
Your original, valid identity document.
-
An unlocked phone compatible with the physical SIM or eSIM purchased.
-
The SIM packaging, card number and purchase receipt.
-
Access to the operator’s registration instructions and any confirmation messages.
Follow the operator’s sequence:
-
Insert the physical SIM or install the eSIM as instructed.
-
Open the registration link or use the operator’s designated registration page.
-
Scan your identity document and check the captured details carefully.
-
Submit the information and complete any follow-up verification.
-
Wait for confirmation, then test mobile data with Wi-Fi switched off.
Manual verification can take longer, particularly when scanned information needs correction. Avoid assuming that paying for a card means it will be usable immediately.
Buy an unregistered card and register it under your own identity. Cards advertised as already registered to someone else should be avoided.
Payment and when validity starts
SoSIM’s shop lists Visa and Mastercard among its payment options, making purchase possible without relying on a local payment app. Payment methods vary by seller.
Check activation timing before inserting or installing a SIM far ahead of your trip. SoSIM starts counting SIM validity on insertion or installation, and its default local package starts with activation. The card’s overall expiry date and the data package’s end date are separate.
Will Your Hong Kong SIM Work in Macau or Mainland China?
Crossing from Hong Kong into Macau or Shenzhen can change which allowance your phone uses. Look for the destination explicitly in the package’s coverage.
The selected cards handle this differently:
-
csl’s three-day Discover pass: the shared portion works in Macau; its Hong Kong-only data stays separate.
-
CMHK’s listed tourist cards: Macau has its own daily allowance. Do not assume a similarly named card includes Mainland China.
-
SmarTone’s HK–Macau card: the shared allowance applies to those two destinations.
-
SoSIM’s local package: travel data is a separate purchase.
-
Roafly’s Hong Kong country package: covers Hong Kong; it should not be treated as a Macau or Mainland China package.
Before a border crossing, confirm the destination, available roaming allowance, activation instructions and applicable expiry time. Enabling data roaming changes a phone setting; it does not add a destination to your purchased package.
Local SIM or Roafly eSIM?
Local prepaid SIMs deserve consideration in Hong Kong because some offer large allowances at low upfront prices. Included local calls and a Hong Kong number can also be useful for contacting businesses or receiving messages.
Roafly is useful when you want to arrange mobile data before departure, retain your primary SIM and avoid a physical purchase or local SIM-registration process. Its Hong Kong service is data-only, with csl and SmarTone listed as supported networks and no eKYC identity-verification requirement.
-
Selected 30-day packages: 5GB for US$9.90, 10GB for US$14 and 20GB for US$20. These are selected options from the catalogue.
-
Hotspot and top-ups: sharing uses the purchased allowance without a separate hotspot quota; top-ups are supported.
-
Calls and messages: no local phone number or conventional calls and SMS are included.
Roafly standard prices confirmed September 4, 2026; prices may change.
Your trip gives you a useful decision rule:
-
Prioritising data per dollar or local calls: compare local prepaid packages first.
-
Prioritising preparation before arrival: consider Roafly on an unlocked, eSIM-compatible device.
-
Visiting Macau or Mainland China too: confirm explicit coverage for every destination.
-
Using a phone without eSIM support: buy a compatible physical SIM.
If you want to investigate travel eSIM selection further, compare Hong Kong eSIM options before choosing a plan.
Hong Kong SIM Card FAQs
Can I buy a local SIM for an eSIM-only phone?
Yes. SoSIM offers a local eSIM, and csl has an eSIM version of its Discover Hong Kong range. Check the exact eSIM package before paying, since a physical-card offer does not automatically have identical digital terms. Local registration still applies.
Can I keep a Hong Kong number after my data package expires?
Some prepaid services allow the number and stored balance to remain valid beyond the data package. SoSIM, for example, distinguishes the local package’s 30-day period from the SIM’s longer validity. Check both dates and the operator’s recharge conditions before relying on the number for a future visit.
Does adding credit automatically give me more data?
Adding stored value and buying a data package can be separate actions. Some monthly services renew from sufficient balance, while other passes require a new subscription. Check that the intended package is active after recharging.
Hong Kong’s local SIM choice comes down to how much data you need, whether you want a local number and where you will travel next. Match those needs to the exact card, complete registration and check that the connection works before relying on it.
Roafly publishes this guide and sells the travel eSIM alternative discussed above.
