Kelvin Wong
Telecom pricing researcher
Kelvin Wong is a house pen name for DealSifu’s editorial output, not an independently identified reviewer. The telecom desk covers mobile plans, home broadband and MVNOs at DealSifu. It maintains the site's Hong Kong price database from providers' public tariff sheets, records available verification dates, and produces the step-by-step switching guides.
Verification approach
Kelvin Wong starts with original tariff sheets, service terms, official registers or coverage data and ties every material figure back to its source. Where a comparison involves a calculation, the inputs and assumptions are retained. Details that cannot be confirmed from public evidence are labelled as unknown instead of being presented as fact.
Coverage areas
- Mobile plan & SIM-only pricing
