   For a Hong Kong number without a long contract, the main options are prepaid SIMs and no-contract monthly plans from the big carriers. Prices below come from pages dated between April and October 2026, so confirm them before you buy.

   Options worth comparing

   • SmarTone prepaid: This is the clearest "keep my number" option. Its HK$118 local prepaid SIM is marketed as keeping your phone number while still receiving SMS/OTP from Hong Kong overseas. SmarTone also has a $65 local prepaid SIM card with a fixed monthly charge included with data and voice call.

   • SoSIM: This is a no-contract option with a strong data allowance. Its HK$33 Hong Kong plan is listed as Hong Kong 50GB FUP / 30 Days , and it says you can port in as fast as 3 days via online application. It also states there is no contract, no admin fee, transparent pricing .

   • 3HK (Three): Its prepaid range is fairly broad. One guide says these SIM cards provide flexibility with no contracts or administrative fees. There are many options, including 2 GB to Hong Kong SIM cards with unlimited data allowances and varying voice minute allowances. Prices range from 19 to 498 HKD (~$2 to $63) with mainly 30-day validity periods. Its annual cards are also cheap. A price comparison site lists a 3HK Hong Kong local 395-day 66GB annual card , and another lists a 365-day 12GB annual card at HK$30.

   • CSL More Mobile: This is a popular budget choice. One expat guide says the CSL More Mobile sells a $48 prepaid SIM with 30GB of 5G data and 200 minutes of local voice valid for 30 days. It is available at 7-Eleven without an HKID (per that guide's table).

   • China Mobile Hong Kong (CMHK): Its prepaid plans suit people who cross into Shenzhen. An expat guide says CMHK is the cross-border specialist , and that prepaid is available without an HKID.

   Things to check before you commit

   • Registration: Hong Kong requires real-name registration for SIMs. SoSIM's page says no registration needed (except Hong Kong) , so expect to register with your ID for local numbers.
   • Number retention rules: Prepaid plans can expire or be deactivated if unused. Read the validity and recharge terms, especially for annual cards, since you want to keep the number long-term. The sources I found did not spell out these rules, so check directly with the carrier.
   • Data-only eSIMs: Some cheap eSIMs do not give you a Hong Kong number. For example, one provider says its eSIM doesn't include a Hong Kong phone number, traditional voice calls, or SMS. Make sure you buy a plan that includes voice and SMS if you need the number.
   • Price comparison: An aggregator reports that the cheapest local 30-day prepaid SIM starts from HKD $7 , and annual cards start around HK$30. Very low prices often come with conditions, such as a short validity period, limited voice minutes, or a shop-specific offer, so compare the total value rather than the headline price.

   Simple recommendation: If you want the number to stay active for a long time with minimal fuss, compare an annual prepaid card from 3HK or SoSIM against a monthly prepaid plan from SmarTone or CSL. Choose the monthly option if you use a lot of data, and the annual card if you mainly want to keep the number and use light data.
