Hong Kong SIM Cards & Home Internet: The Newcomer's Guide (2026)
Hong Kong has some of the cheapest mobile data on earth — and a confusing alphabet soup of carriers. Here's the simple version: what to buy on day one, what to switch to when you settle, and how home broadband works.
Day one: get a prepaid SIM at the airport
You need data the moment you land. Two MVNO brands dominate the value end:
| Brand (network) | Starter deal | Renewal | Notes |
|---|---|---|---|
| SoSIM (3HK network) | HK$33: 50GB + 1,500 local minutes, 30 days | HK$48 / 30 days (60GB + 5,000 min) | Best data-per-dollar; eSIM available; buy at 7-Eleven, Circle K, PARKnSHOP |
| Club SIM (CSL/HKT network) | Top-up based, e.g. HK$38 / 90 days (1GB) | Packs from HK$48–128 | Great for keeping a number alive cheaply; strong CSL coverage |
Both are sold at airport 7-Elevens and convenience stores citywide. Real-name registration is required — bring your passport; activation takes minutes.
eSIM option: both brands offer eSIM if your phone supports it — no store visit needed.
Settling in: the big four carriers
Once you have an HKID and a local bank account, the main carriers (with shops everywhere) offer postpaid plans with handset deals:
- CSL / HKT — largest network, premium pricing, best coverage in remote areas.
- SmarTone — strong customer service reputation, competitive 5G plans.
- 3HK (Three) — aggressive pricing, owns SoSIM.
- China Mobile Hong Kong (CMHK) — cheapest of the big four, great if you travel to the mainland often (cross-border data bundles).
Typical postpaid: HK$100–200/month for generous 5G data. The MVNOs above (SoSIM/Club SIM) remain cheaper if you don't need a handset subsidy — many long-term residents never leave them.
MyRepublic is a smaller broadband-first player that also sells no-frills mobile plans — worth comparing if you want one provider for both.
Home broadband: HKBN vs Netvigator (and friends)
- HKBN (香港寬頻) — the price fighter. 1000M fibre plans are frequently HK$100–150/month on promotion. Online signup, fast installation.
- Netvigator (HKT) — the incumbent, slightly pricier, bundles with Now TV and CSL mobile for discounts.
- 3Home Broadband / SmarTone Home 5G — 5G home broadband (a router, no fibre installation) suits renters who move often or live in old buildings without fibre.
Newcomer tips:
- Contracts are typically 24 months — ask about the early termination fee before signing.
- Installation in most buildings takes 3–7 days; serviced apartments usually include wifi already.
- "1000M" is the standard product now; anything slower is rarely worth the small saving.
Frequently asked questions
Can I keep my foreign number too?
Yes — use dual-SIM or eSIM: keep your home number on eSIM for bank SMS codes, and run Hong Kong life on the local SIM. Club SIM's pay-as-you-go top-ups are ideal for a number you barely use.
Do I need an HKID for a postpaid plan?
Generally yes, plus proof of address. Prepaid SIMs only need a passport for real-name registration.
Is public wifi usable?
"Wi-Fi.HK" hotspots are everywhere (MTR stations, malls, libraries) but slow and unencrypted — fine for maps, not for banking.
