Senior deals in Hong Kong are real and properly cheap. As of mid-2026, CMHK, csl, Sun Mobile, China Unicom and SoSIM all run dedicated plans for people aged 60 or 65 and over — from a $38 four-G plan to 5G options with unlimited calls. The trick is picking the one that matches how they actually use the phone, not just the lowest sticker price.

The no-contract route: SoSIM’s SoJoy 360 and other cheap cards
- SoSIM’s SoJoy 360 (60+): HK$396 covers 360 days — around $33 a month, the cheapest real senior option we found. No contract, no admin fee, and as a prepaid card it can never overspend.
- Each 30-day cycle gives 30GB FUP local data plus 3,000 local call minutes, and there’s 6GB of China / Macau / Taiwan travel data across the 360 days (top up at $10/GB beyond that).
- Anti-scam call blocking built in (drawing on the Hong Kong Police’s scam-call list), and SIM validity is guaranteed for at least 420 days so the number won’t quietly die.
- Buy it new at Easy66 (in store or online), or upgrade a $33 SoSIM from PARKnSHOP/Watsons. A family member can log in with their own email to help manage the account remotely.
- Regular SoSIM (any age): a new $33 card gives 50GB for 30 days plus 1,500 minutes, and monthly 4.5G packs run from about $48 (60GB) after the January 2026 price change. Runs on 3HK’s network.
- SmarTone 月用輕量王: $65 per 30 days for 5GB (capped to 2Mbps after) and 2,000 free minutes. No contract, no application — just top up.
- Lucky SIM’s $8/month postpaid plan (1GB + 100 minutes, 24-month term) is the cheapest way to keep a Hong Kong number alive for someone who barely uses data.
- csl’s Club SIM is another no-contract option on csl’s network — buy data packs as needed, no term.
Why a proper senior plan beats a bare prepaid card — and what actually matters
- Staff do the paperwork — registration, porting and setup are handled in store or by phone, not via self-serve forms.
- No 120-day recorded-voice prompt. New prepaid cards play a “new SIM” announcement when you dial for the first 120 days — a real pain for an older person making calls.
- Real support — shops and hotlines. Many prepaid brands are app- or online-only.
- Lost the card? Postpaid can reissue it at the store the same day; prepaid can take days.
- Renewal is automatic — no risk of the number expiring because nobody remembered to top up.
- Free voicemail, call forwarding and call filtering; prepaid usually charges extra for these.
- Bill control: prepaid can never overspend, while a postpaid plan needs a clear, fixed monthly fee.
- Coverage where they live — all four operators cover all 18 districts, but ask the store about reception before signing if they live in remote New Territories. Senior plans and SoSIM’s 360 also bundle scam-call filtering, which matters given how many fake-call scams target older people.
Cost check: a light user on 5–10GB a month
Here’s the real monthly cost of the options above, cheapest first. Prices are as of mid-2026 and promotions shift often, so check current offers before signing. Consumer Council tip: don’t compare headline prices — add the monthly admin fee (often $18) and any rebates to get the real cost, keep a written record of any verbal promises, and don’t assume a “senior” label is automatically the best deal.
| Option | Monthly cost | What you get |
|---|---|---|
| SoSIM SoJoy 360 (60+) | ~$33 | 30GB/mo + 3,000 mins; 6GB Greater China; no contract |
| CUniq 樂悠 4G (60+) | $38 | 8GB + unlimited calls; free China number |
| Sun Mobile 樂悠 4.5G (60+) | $58 | 5GB + unlimited calls; admin fee waived |
| csl Smart 爸媽 4.5G (65+) | $58 | 5GB + unlimited calls; admin fee waived |
| CMHK 長者 5G (60+) | $88 | 10GB + unlimited calls; China/Macau/TW incoming free |
| csl Smart 爸媽 5G (65+) | $98 | 20GB + unlimited calls; China/Macau roaming included |
Setting it up for them: registration, porting, roaming safety
- Real-name registration: every SIM in Hong Kong has required it since the SIM registration rules took effect in September 2021 (the prepaid transition finished in February 2022). Stores usually register on the spot with their HKID — no separate errand.
- Keeping their number: porting is free — just apply at the new operator with their HKID. Verification usually takes a few working days and is suspended during the first four days of Chinese New Year. Time the switch after the current contract ends and before the billing-cycle cut-off to avoid double charges.
- Turn data roaming off by default (or ask the store to do it) — surprise roaming bills are the classic complaint among older users. Before picking a data size, check how much they actually use with our data-usage guide.
Frequently asked questions
What is the cheapest real senior plan in Hong Kong?
SoSIM’s SoJoy 360 works out to about $33 a month (60+, no contract, 30GB + 3,000 minutes per 30 days, plus 6GB of Greater China travel data). Among postpaid plans, CUniq’s 樂悠 is $38 for 8GB, Sun Mobile and csl’s 4.5G plans are $58, and CMHK’s 5G plan is $88. Note the age gates differ — csl requires 65.
Is prepaid or a monthly plan better for an older relative?
Prepaid is the safest against bill shock — you can never overspend, and SoSIM’s 360 even lets a family member manage it remotely. A monthly senior plan is better when they want in-store support, automatic renewal (nothing to remember to top up), free voicemail and no 120-day new-card call prompt. Both work; it comes down to whether you prefer hard cost control or zero-fuss support. See our prepaid vs monthly guide for the full trade-off.
Does a senior need 5G?
No. For calls, WhatsApp and light browsing, the 4G/4.5G senior plans at $38–$58 are plenty, and they cost noticeably less than the $88–$98 5G tiers. Take 5G only if they stream a lot of video on mobile data. If you do want 5G, our cheapest 5G guide covers the low end.
What do I need to set a plan up for my parent or grandparent?
Bring their HKID for the mandatory real-name registration (every SIM in Hong Kong needs it). For most senior plans, proof of age (their HKID) is enough at the store; CMHK’s special $38 plan also needs proof of CSSA or Old Age Living Allowance. To keep their existing number, just ask the new operator to port it — it’s free and usually done in a few working days. Details are in our porting and SIM registration guides.
