Claude · 在香港用手機，每月預算港幣150元、需要約50GB數據，有哪些電訊品牌值得比較？ in Hong Kong?

Short answer: Based on 2026 price roundups, China Mobile Hong Kong (CMHK) and 3HK are the main options that fit HK$150. csl, SmarTone and HKBN are worth checking if you can stretch slightly or want specific perks. Prices change often and the sources disagree on some figures, so confirm on each carrier's official site before you sign.
Brands to compare
- CMHK (China Mobile Hong Kong): The most promising budget pick. One roundup lists
中國移動香港 $129 with 50GB on a 24-month contract , and says CMHK's $149 plan is 50GB shared between Hong Kong and mainland China, for customers porting their number . Another source lists a $179 plan for 50GB shared across Hong Kong and mainland China , so check which price applies to you.
- 3HK: Also fits the budget. One listing shows
50 GB local data with 3 GB of Chinese Mainland and Macau shared data at $148 per month . Note that 3HK's 50GB plan at $148 has a 24-, 30- or 36-month contract option , and older listings show an admin fee of HK$28 unless waived.
- csl: Slightly above budget. One roundup lists
csl at $168 for 60GB, with 3GB of mainland data and a 24/36-month contract . Another source notes csl's $158 / 50 GB plan with a $18 admin fee waiver , so the pricing differs between sources.
- SmarTone: Usually more expensive. One roundup lists
SmarTone at $179 for 60GB, with mainland and Macau data included and a price increase from its older $138 plan . One review says SmarTone's network stability in MTR and indoor areas is strong, but its data value is weaker .
- HKBN: Possibly cheap. One roundup lists
HKBN at $125 for 60GB on a 30-month contract, with no mainland or Macau data listed . Its 100GB figures in the same source look inconsistent, so verify directly.
- 1O1O: Not a value pick at 50–60GB. The same roundup lists
1O1O at $389 for 60GB .
No-contract options
If you want to avoid a 24–36 month contract, the no-contract sub-brands are weaker on 50GB. One comparison notes that MySim (CMHK) supports 5G with 8GB local data for HK$48 per 30 days , which is well short of 50GB. Birdie is listed as 4.5G with 42Mbps , not 5G. Also check whether a no-contract plan with 50GB is actually 5G before you assume it is.
What to check before choosing
- Contract length and fees: Many of the lowest prices require 24–36 months. Compare the total cost over the contract, including admin fees and any early termination charges.
- Data scope: Some plans cover only Hong Kong data, while others share data with the mainland and Macau. If you cross the border often, the shared plans may be worth more than a slightly cheaper local-only plan.
- Speed after the cap: Many plans drop to a lower speed (often 1 Mbps) rather than cutting you off, which matters if you use a lot of data.
- Coverage: Check indoor and MTR coverage where you live and work.
Practical shortlist: Start with CMHK's HK$129 (local) or HK$149 (shared with mainland) plans, and 3HK's HK$148 plan. Compare them with csl's 60GB plan if you want more data and can pay a bit more. Confirm the current price, contract, admin fee, and included cross-border data on each official website before subscribing.
Claude · 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?

Since you cross often, the most useful option is a plan that includes Mainland China data on a Hong Kong number. A standard Hong Kong plan stops working at the Shenzhen border. A Hong Kong SIM or eSIM does not work once you cross into Shenzhen, and vice versa. Here are the main carriers to compare. Prices and terms come from third-party guides and carrier pages, so check the current offers before you sign up.
1. China Mobile Hong Kong (CMHK) This is the strongest fit for weekly Shenzhen trips. Its Greater Bay Area plans include free data roaming in Mainland China (5G) and Macau (4G) , and one guide says that CMHK almost always wins once you do the maths over a 12-month period. Compare its total monthly cost against a cheaper base plan plus roaming add-ons.
2. China Unicom Hong Kong (CUniq) This is a shared-pool option. One guide reports that China Unicom HK offers shared data plans starting from HK$398 per month for 30 GB of combined Hong Kong and mainland China data . The same source notes that these are contract plans (typically 24 months) , so check the commitment before you commit.
3. 3HK (Three) This is the value option. One source says its flagship $88 per month plan bundles 32GB of local data, an additional 2GB shared with Mainland China and Macau . That mainland allowance is much smaller than CMHK's, so it suits lighter cross-border use.
4. SmarTone Mainland roaming here is limited to higher tiers. One guide says a mid-tier $148 plan adds 5GB of Mainland and Macau roaming data . Choose it mainly if strong 5G coverage matters to you.
5. CSL (HKT group) CSL's 5G plans list Mainland China and Macau roaming, but the terms say the roaming package must be subscribed separately and that the customer has activated IDD, roaming service and subscribe to Data Roaming Day Pass service . Read the fine print before relying on it.
Other options to know about
- eSIM from a regional provider (for example Roami or Airalo): these can cover both places, but they're better for occasional trips than daily commuting. One guide notes that
a China-only eSIM plus a Hong Kong-only eSIM is almost always cheaper than a regional plan that covers all three .
- Prepaid SIMs: if you consider one, note that 7-Eleven says
from 17 June, 2026, all prepaid SIM cards do not support Activation in Chinese Mainland. Activation has to happen in Hong Kong.
How to choose
- If you cross most weeks, start with CMHK's Greater Bay Area plan and compare its price with 3HK plus add-ons.
- If you cross occasionally, 3HK or a regional eSIM may cost less.
- Check whether the mainland allowance is shared or separate, whether it is 4G or 5G, and whether the contract is 12 or 24 months.
- Confirm your phone supports dual SIM or eSIM, so you can keep a second line active.
