Methodology
How this mobile-plan list is built
DealSifu ranks live Hong Kong mobile plans from public provider data, then keeps the source and review trail visible so you can sanity-check each deal.
- Sources: Operator and MVNO websites, offer pages and published plan terms are the primary sources.
- Ranking: Default sorting uses the current effective monthly price, then lets you filter by data, network, eSIM, contract and provider.
- Caveat: Promotions and retention offers can change quickly, so always confirm the final price with the provider before switching.
- Freshness: Changed rows are reviewed before publishing, and each plan card links back to the stored source where available.
Prices are for reference only and may be out of date. Always confirm with the provider before purchasing.

Read guide →Frequently asked questions
What is the cheapest mobile plan in Hong Kong?
The cheapest plans are usually prepaid SIMs and MVNO monthly plans, which can start under HK$50 a month for a few GB of 5G data. The exact cheapest plan changes with promotions — sort the live list by price to see today’s lowest.
Is a SIM-only plan better than a contract with a phone?
For most people, yes. Buying a phone outright and taking a SIM-only plan is usually cheaper over two years and lets you switch providers freely, because a contract phone bundles the handset cost plus interest into the monthly fee.
Do MVNOs have worse coverage than operators in Hong Kong?
No — MVNOs run on the operators’ own networks, so coverage is essentially the same. The differences are in extras like priority data at congested times, premium roaming packages, and physical retail support.
