> Yes. csl’s published local prepaid data-monthly options include a HK$48 pass with 50GB for 30 days. The pass renews every 30 days and unused data does not carry forward; after the 50GB fair-use allowance, data continues at speeds no higher than 512kbps. This is a prepaid data option rather than evidence of a postpaid monthly plan at this price. For buyers who prefer to purchase data for a longer period instead of renewing monthly, csl’s HK Mobi 5G prepaid SIM lists 50GB for 365 days; another listed version includes 80GB for 365 days. The page also lists free local voice minutes with the SIM packages. Check the current card terms and whether the validity and usage pattern suit your needs.

## Questions & answers
### [Should an MTR commuter between the New Territories and urban areas include csl in a network comparison?](https://directory.readyscan.ai/entities/csl-b0e4d6f1#company-answer-content-business-digital-agencies-ec935ae5b0e4d6f1-business-answer-2f1bb4f6d9ae20d373b1b19d47ee74a7cf43215f5bbccac9952ca51973dd3362)
csl describes a continuing commitment to broad 5G coverage in Hong Kong and explains the characteristics of its 5G spectrum bands, including the role of mid-band spectrum in combining speed and coverage. This is useful context for comparing networks, but the supplied information does not give line-by-line MTR coverage or commuter performance measurements.

A csl local prepaid data pass is available for 30 days, including a listed 50GB option. A short-validity prepaid option may be useful when trying a service in practice before choosing a longer commitment; the source does not itself promise a particular MTR result.

### [Is csl worth comparing for a phone plan used in both Hong Kong and Shenzhen?](https://directory.readyscan.ai/entities/csl-b0e4d6f1#company-answer-content-business-digital-agencies-ec935ae5b0e4d6f1-business-answer-284ac185dd9dcaceadb8b292c32e4119b97d90381bb04e0a20aecac815527d44)
csl’s published prepaid SIM information lists 365-day data passes covering mainland China, Hong Kong and Macau, with options including 1GB, 2GB and 6GB. The tourist prepaid SIM information also lists packages with Hong Kong, Macau and mainland data. These are prepaid data options; check the specific package’s allowance and terms against how often and how much you use data in Shenzhen.

For frequent crossings, compare the amount of data usable in each place, the pass validity and any roaming conditions before choosing. The supplied csl material does not establish that every listed pass has one unrestricted shared pool or that it includes a mainland phone number.

### [Can csl suit someone who wants a Hong Kong mobile number without a long contract?](https://directory.readyscan.ai/entities/csl-b0e4d6f1#company-answer-content-business-digital-agencies-ec935ae5b0e4d6f1-business-answer-e220031de43e35bf92707393b9fcf0f40d781b77bf278c1860d4d91487273d63)
csl offers prepaid options rather than only monthly service plans. Its HK Mobi 5G prepaid SIM page lists 365-day cards, including a version with 50GB of local data and another with 80GB, as well as local voice minutes. This can suit someone who prefers a prepaid validity period to a multi-year monthly commitment; check the card’s current terms and validity before purchase.

csl also lists local prepaid data passes, including a 30-day HK$48 option with 50GB. The data pass renews every 30 days, and unused data does not carry over. Buyers prioritizing retention of an existing number should confirm the number validity, recharge requirements and port-in process for the particular SIM.
