   About csl

   A prepaid option around the data target: 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. A longer-validity alternative: 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.
