Greater Bay Area travel eSIM comparison
Count the data you need on each crossing before changing your Hong Kong monthly plan. For occasional Shenzhen or Macau visits, one fixed-validity pack may be enough. CMHK’s regional prepaid eSIM guide lists HK$38 for 5GB over 30 days across Mainland China, Hong Kong and Macau; it does not include ordinary voice or SMS.
Editorially checked:
Lowest listed pack price: CMHK Greater Bay Area Pass · 15GB · 30 days at HK$88 per 30-day pack. Allowances and validity vary; confirm before buying.
What matters here
- This CMHK product must first activate in Hong Kong or Macau, not in the Mainland.
- Its Hong Kong data requires real-name registration.
- Five gigabytes shared across four trips averages 1.25GB per trip; heavy use on one trip leaves less for the rest.

FAQs
Will crossing the border renew my allowance?
Not for a fixed shared pool. Compare that model with a plan explicitly offering a daily or monthly Mainland allowance. Record when the daily period resets and whether unused data carries over; the GBA label alone answers neither.
What should I set up before reaching the checkpoint?
Complete the selected product’s registration and activation, save tickets offline, and select the intended data line. Allow for network registration after crossing rather than planning an urgent payment around a promised one-minute handover.
