Split the bill into four amounts
| Charge | Action |
|---|---|
| Base plan plus compulsory fee | Use their combined amount when comparing. A waived fee may return after a promotion. |
| Optional recurring services | Check entertainment, extra SIMs, roaming subscriptions and device protection. Confirm cancellation terms and any bundle discount you would lose. |
| Usage charges | Identify the actual trigger: roaming, calls, data overage or premium SMS. A bigger local data plan will not fix every kind of charge. |
| Handset instalments | Separate hardware from service. The phone payment can remain due after a number transfer. |
Take screenshots of the itemised bill and the contract end date. For an unexpected charge, ask for the service name, activation date and evidence of subscription. Keep the case number and follow the provider’s payment and dispute instructions rather than simply ignoring the bill.
Calculate the switching break-even point
Suppose your current service costs HK$198, a suitable replacement costs HK$78 and leaving now costs HK$600. The monthly saving is HK$120, so it takes five months to recover the exit charge. If the old commitment ends in two months, waiting costs HK$240 of missed savings and avoids a HK$600 exit payment. These are example figures; use your written settlement quote.
Ask for two quotes with the same requirements
Give your current carrier and a competing carrier the same data requirement and contract length. Request the total payment, compulsory fees, rebate timing and price after the offer ends. OFCA’s pre-contract checklist covers the terms to establish before agreement. Do not accept extra years or an unwanted handset merely to make the monthly number look smaller.
Set a reminder before the next renewal decision. Record the notice requirement and ask how the service continues when the commitment ends. If you keep your number, submit a port-in request through the receiving carrier and leave the old line active until the transfer succeeds.
