Older parent sold a long telecom contract?
How families can check, cancel and complain

Your parent used to pay a few dozen dollars a month for their phone, and suddenly they’re on a multi-year contract costing several times more, with a secondary SIM, roaming data and cloud storage? This page shows how to check the contract, cancel what they don’t need, and where to complain.

Found an unsuitable contract?

Act early. Find the contract and bills, check what’s included, then contact the operator. The Consumer Council has an elderly hotline: 2110 2288.

Real case: man in his 80s sold a 67-month contract

Case published by the Consumer Council, 2025

  • • The complainant’s father was in his 80s, had cataracts, and had always used a mobile plan under HK$100 a month.
  • • In August 2024 he signed, in a shop, a 67 months contract, with a monthly fee of about HK$600.
  • • It included a secondary SIM, two roaming data passes, two roaming voice and data bundles, and 4 cloud storage plans (HK$60 a month after a 3-month trial).
  • • He didn’t travel and didn’t need a secondary SIM. At first the operator would only cancel the secondary SIM.
  • • After Consumer Council conciliation, the operator agreed to cancel all secondary SIMs and add-on services.

Key point: a signed contract doesn’t mean it can’t be changed. In this case, the family followed up and the extra services were cancelled.

Common sales traps

TrapWhat to watch for
Very long contract termFar longer than usual, locking in the fee for years
Add-ons they don’t needSecondary SIMs, roaming data, cloud storage – often not needed
Free trials that turn into chargesMonthly charges start automatically after the trial
Phone or door-to-door salesA verbal yes can create a contract, and terms may not be fully understood

What rights do older customers have?

Cooling-off for door-to-door sales

Contracts made during an unsolicited home visit generally have a cooling-off period of at least seven days, during which you can cancel free – unless service has started, installation has begun or gifts were received.

No unfair sales practices

The Trade Descriptions Ordinance prohibits false trade descriptions, misleading omissions and aggressive commercial practices. The Communications Authority enforces it for telecom licensees.

Written confirmation for phone contracts

After a contract is made or extended by phone, the operator must give written confirmation within a reasonable time.

No automatic renewal

Unless the customer specifically says so or confirms it, operators cannot automatically extend or renew a contract.

How family can help

1. Gather the contract and bills

Check the signing date, contract term, total monthly fee, and the charge and trial period for each add-on.

2. Talk it through with them

Ask where they signed, what the staff said, and whether they really need a secondary SIM or roaming. Note the key points.

3. Check for a cooling-off period

If it was sold door-to-door and service hasn’t started, you may still be able to cancel free within the cooling-off period – act fast.

4. Call the operator together

Operators usually need the account holder’s authorisation, so call together. You can use this script:

“Hello, I’m the account holder [name], and my family member [your name] is with me. On [date] I signed a [term] contract, but I don’t use the [secondary SIM / roaming data / cloud storage] at all, and it wasn’t clear when I signed. I’d like these cancelled and my monthly fee adjusted. Could you give me a reference number, please?”

5. Complain in writing

If the call doesn’t work, use the template below and send it with copies of the contract and bills.

6. Get help from the Consumer Council or Communications Authority

If the operator won’t help, ask the Consumer Council to conciliate. For misleading or pressure selling, complain to the Communications Authority.

How to protect older family members

  • Go with them when they renew or switch operator
  • Ask about the contract term and total monthly fee before signing
  • Ask what each add-on is for – skip it if not needed
  • Note when free trials start charging
  • Remind them not to agree to phone sales on the spot
  • Check their mobile bills regularly

FAQs: telecom contracts and older people

My parent was sold a long contract. Can it be cancelled?

Start by asking the operator to cancel unneeded SIMs and add-ons. In a Consumer Council case involving a 67-month contract, the operator agreed after conciliation to cancel all secondary SIMs and add-ons. If it was a door-to-door sale and service hasn’t started, the cooling-off period may still apply.

Is there a cooling-off period for telecom contracts?

Only in some cases. Under the industry code, contracts made during an unsolicited home visit generally have a cooling-off period of at least seven days for free cancellation. It no longer applies once service has started, installation has begun or gifts were received.

Can family members complain on an older person’s behalf?

Family can help gather documents and contact the operator. Operators usually need the account holder’s authorisation, so call together or arrange authorisation first. You can also call the Consumer Council elderly hotline on 2110 2288.

Where can I complain if the salesperson lied or used pressure?

Telecom licensees’ sales practices are covered by the fair trading provisions of the Trade Descriptions Ordinance, enforced by the Communications Authority – including false descriptions, misleading omissions and aggressive practices. Call 2961 6333 or use the complaint form.

How do I find out which add-ons are in the contract?

Check the contract and itemised bills line by line – base fee, secondary SIM, roaming passes, cloud storage – and watch for charges that start after a free trial.

How can I stop this happening again?

The Consumer Council advises buying only what you need, reading the terms carefully, and having older people shop with family or friends. Ask about the term, total monthly fee and what each add-on is for before signing.
