   Based on the sources I found, SmarTone, csl (1O1O), CMHK, and 3HK are the four operators to compare. The evidence is mixed, so test your own commute route before committing.

   Start with the MTR's own status. The MTR says all MTR stations were currently covered by 5G services . Upgrades to speed and capacity are still underway. As of the end of April 2026, upgrade works have been completed at 17 stations , and upgrade works for the remaining seven stations including Mei Foo (MEF - TWL), Lai King (LAK- TWL), Tsing Yi (TSY), Kowloon Tong (KOT - KTL), Lok Fu (LOF), Lam Tin (LAT), and Tiu Keng Leng (TIK) are in progress. These are scheduled for completion between 2026 and 2027. Several of these are New Territories stations, so your experience may improve during the contract period.

   Independent data (Opensignal, May 2026). This is the most credible source I found. Its per-operator figures are hard to map reliably from the extracted text, so check the table directly on the report page. What I can say is that the report covers the Opensignal Coverage Experience metric , which represents the experience users receive as they travel around areas where they would reasonably expect to find coverage. That is closer to your commute than a speed-test score.

   Operator notes (secondary sources, treat with caution):

   • CMHK: One review says China Mobile Hong Kong delivers Hong Kong's fastest 5G median download speed . Another source reports that user reports on Reddit (January 2025) indicate that CMHK's in-tunnel MTR performance at certain stations on the Tsun Wan and Kwun Tong lines can be variable during peak hours . Its strength is speed, and possibly weaker MTR performance at peak times.
   • SmarTone: It is the one most often recommended for MTR commuters. One guide says SmarTone earns its roughly $20 per month premium over 3HK if you commute underground. Its claims about every MTR station are not independently verified in these sources.
   • csl (1O1O): One source says csl delivers the most consistent network experience for enterprise and power users prioritizing reliability. That suggests it is a good choice if stability matters more than peak speed.
   • 3HK: Its main advantage is coverage. One source says the carrier is the only Hong Kong MNO to deliver 5G connectivity in every road tunnel , though this is a vendor-adjacent review. Another guide says the network trades raw MTR-station 5G coverage for price , which conflicts with that claim. It also notes 3HK is competitive above ground but weaker inside MTR tunnels .

   Suggested approach:

   1. Check the Opensignal May 2026 table for the operators' coverage-experience and 5G-availability numbers.
   2. Look at your specific line. Underground coverage is the key variable. Note that the MTR's own page lists pending upgrades for Tsing Yi, Kowloon Tong, Lai King, and others, so your station pairs matter.
   3. Use free trials, eSIM options, or short-term plans to test your route at peak hours (roughly 8–9 AM and 6–7 PM) before signing a contract.
   4. If you want a backup, a second eSIM from a different operator can cover gaps.

   Plan prices change often, so check each operator's current offers directly.
