OFCA’s FAQ says HKID holders use the original HKID. A person without HKID can use an accepted valid travel document; HKSAR and BN(O) passports are specifically excluded as registration identity documents. Check with the carrier if your document type is unusual instead of paying first and hoping the upload succeeds.
Prepare these before you need the connection
- Original identity document, order reference, SIM packaging or eSIM details, and access to the purchase email.
- A working Wi-Fi connection for the carrier’s official registration page. The unactivated local SIM may not provide the data needed to finish setup.
- Your exact phone model and carrier-lock status. Registration approval cannot make an incompatible eSIM work.
Buying in a shop does not always include setup
A convenience-store sale may only give you the sealed product. If you need help, confirm that the operator’s shop or selected seller will register that specific product and accept your document. Allow time for manual review; the provider controls its processing time. Do not plan an essential call around an unconfirmed promise of instant activation.
After confirmation, turn off Wi-Fi and test mobile data. If the product includes a local number, test the call or SMS function you need as well. An eSIM shown in Settings proves installation, not that identity verification and the purchased service are active.
What about an overseas travel eSIM?
An overseas-issued roaming product can follow a different activation and identity process from a local Hong Kong SIM. Follow that seller’s requirements; do not assume the words “Hong Kong eSIM” establish either an exemption or a local phone number. Check whether the product is data-only and what starts its validity.
Avoid a pre-registered card in someone else’s name
Use your own documents and the official channel. A seller promising that you can skip registration by using an already-registered card can leave you unable to prove ownership, replace the SIM or recover the number. Keep the purchase receipt and account access until after the trip.
