A current CUniq offer, with its conditions
CUniq’s ONE Greater Bay Area 20GB online offer runs from 22 September to 21 October 2026 for new customers taking a 30-month contract. Its terms specify HK$101 a month and waive the HK$18 monthly administration charge during that term. The plan fees alone are HK$3,030 over 30 months; additional usage and optional services remain separate. This is a particular dated offer, not a price for every CUniq applicant.
The same promotion gives a 100-minute GBA voice package whose stated HK$48 monthly charge resumes after the contract. Record when each waiver ends. Check whether the quoted data is shared across regions or is a separate Hong Kong bonus; a local bonus does not increase the Mainland allowance.
Make CMHK quote the same job
Ask for enough data in each place you actually visit, the cost of a Mainland number if needed, overage handling, and the total for the proposed term. A cheaper monthly fee with another year of commitment is a different purchase. For a few short trips, also compare keeping your current line and adding trip data; CMHK’s regional prepaid eSIM has no calls or SMS and must first activate in Hong Kong or Macau.
Check the number before depending on it
For either provider, get the registration documents, activation process and recurring number fee in writing. If the purpose is a particular account’s verification messages, confirm that use with the account provider. Do not port or cancel an existing number merely because a sales page says a new Mainland number is included.
China Mobile HK
Consider CMHK if its written quote covers your actual destinations and number needs at the better complete cost, with a term you can keep.
China Unicom HK (CUniq)
Consider CUniq if you qualify for the specific shared-data offer, will use its regional allowance, and accept the 30-month commitment and post-promotion charges.
