All SIM card users are required to register the SIM cards for activation in Hong Kong. If your prepaid SIM is solely used overseas for travel data and voice services, real-name registration is not required. However, we suggest customers to complete real-name registration to facilitate the use in covered destinations around the world. Click here for registration guide and details.

No real-name registration limit is applied. Customers can cancel real-name registration at any time and register again later (not necessary to use the same identity document). At each telecommunication operator, a personal user can register up to 10 prepaid SIM cards; a company/corporate user can register up to 25 prepaid SIM cards. Customers are required to register again upon change of SIM card (e.g. lost SIM replacement / changed to eSIM), except changing mobile number.

If you use a newly activated prepaid SIM to make a local call, according to The Office of the Communications Authority (OFCA), "This call is made from a new prepaid SIM card" voice alert will be played to call receivers before a call connection, to raise customers' awareness of suspicious calls.
