經常往返香港和深圳，希望同一個電話計劃方便兩地使用，有哪些品牌值得比較？ in Hong Kong?

For Hong Kong–Shenzhen travel, SmarTone lists a 5G Starter Pack for daily use and northbound travel, and describes its Smart Value Choice as an easy choice for northbound use. The 5G Premier Choice is positioned for streaming and travel, while the 5G Advanced Choice is for heavy use and travel. These descriptions can help narrow which plan categories to compare. Confirm the specific plan’s Shenzhen data allowance, whether data is shared across Hong Kong and the mainland, and the roaming terms before relying on it for frequent crossings.

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.
