Lucky SIM has three types of services, each with a different start date calculation reference:

【1】New card eSIM (applicable to LuckySIM / Lucky2):

After completing the payment in our online store, you will receive an eSIM QR Code via email, regardless of whether the eSIM requires real-name registration. Since the eSIM QR Code has an expiration date, it is recommended to install it within 2 months. After successfully connecting to the telecom operator's network, the next step is as follows:

- "Non-real-name registration eSIM": It will take effect immediately and the data plan will officially start

- "Real-name registration of eSIM required": If you have a Hong Kong number, or use Internet data in Hong Kong and Taiwan, you also need to register with your real name to activate it, and the data plan will officially start

【2】Number portability (applicable to physical SIM card/eSIM):

After the payment is completed in this online store, it will be handed over to the transfer specialist for follow-up. After submitting an application for porting, a physical SIM card/eSIM will be issued in advance. You will need to wait for it to be activated after the porting is successful, and the data plan will officially start at that time.

- "Physical SIM Card": Can be received and activated in Hong Kong/overseas

-「eSIM」：Pay attention to the SMS confirmation on your mobile phone. You will also receive an eSIM QR Code/activation code via email for default activation. The phone number and email address must be correct, as the system cannot change or resend.

【3】Add value on behalf of others (applicable to physical SIM card/eSIM):

If you want to add value/renew your phone number, please remember to add value in advance before the expiration date, otherwise your phone number will become invalid! Can't retrieve!

Prepaid card users can simply purchase a recharge plan to increase data/extend validity.

This online store has set up a preset value-added service. If the customer does not provide a valid value-added date within 1 month before payment, this online store has the right to make the value-added service effective immediately after payment, and the data plan will start at the same time.

The number expiry date will be extended from the date of recharge. The new and old validity periods will not be calculated together, but the longest expiry date will be used as the basis.

Lucky SIM has two major brands, "LuckySIM" and "Lucky2", each with different usages:

【1】LuckySIM Hong Kong/Roaming Data SIM Card (Applicable to physical SIM card/eSIM):

All data plans allow free SMS reception worldwide, but not sending. If you have Hong Kong minutes, you can make/receive calls in Hong Kong. However, there is no IDD function for long-distance minutes overseas, so you cannot make/receive calls.

【2】Lucky2 Internet Data Card/Travel Card (Applicable to physical SIM card/eSIM):

All data plans do not have a Hong Kong number, so you can only receive system SMS messages, avoid fraudulent calls and SMS harassment, but cannot make/receive calls.
