Mailing Policy
The product will be mailed within 2 working days via Hong Kong ordinary mail. Therefore, only delivery addresses within Hong Kong can be accepted, and no mailing or tracking number is provided.
Hong Kong postal delivery generally takes approximately 3 working days; remote areas may take longer.
When placing an order, please provide the recipient's full and accurate name and address to avoid delivery failure.
Delivery may be delayed by traffic, weather, or other force majeure conditions. Please arrange your order early to avoid not receiving it before your departure date.
Orders that have already been shipped cannot be modified or changed.

Purchasing Information
Hotspot sharing uses bandwidth, and network speed may vary depending on the terminal device and location. Therefore, minimum network speeds are not guaranteed. Please confirm this before placing your order.
According to fair-use principles, the telecommunications company may, at its discretion, restrict data usage for users who consume large amounts of data within a short period. We recommend avoiding prolonged video viewing or system updates.

Important Notes
The SIM card will be activated automatically after insertion; registration is not required.
The SIM card must be activated within 90 days after ordering. We recommend activating it as soon as possible after arriving in the “Usage Area” to avoid expiration.
Day calculation: calendar-day basis (for example, if a user purchases a 3-day internet plan and installs and activates it at 10:00 a.m. on 9/1, 23:59 on 9/1 is counted as the first day, and the plan will terminate at 23:59 on 9/3).
Time zone calculation: GMT +8 Hong Kong time is used as the standard, not the time zone of the “Usage Area”.
Usage within the data allowance is provided at the specified transmission speed. If usage exceeds the data allowance, the transmission speed will be restricted or reduced to no more than 128kbps.
The SIM card will expire due to late activation, and no refund will be issued.
Please do not insert the SIM card before arriving in the “Usage Area”; otherwise, the customer must bear the risk that the SIM card may not provide the intended or normal service.
Note: Actual connection signal and speed may be affected by various factors, such as the customer's location relative to the transmission station, website server resources, internet traffic conditions and number of users, and the supported speed of the mobile device.

User Guide
Insert the SIM card into your phone after arriving at your destination.
Wait 1–2 minutes; the phone should automatically connect to the network.
With the phone turned on, please enable data roaming and mobile data.
If the phone cannot select it automatically, select “3gnet” as the APN.
Make sure Wi-Fi is turned off; Airplane Mode is turned off; and the network mode is set to 5G/4G/3G/2G.
Popular apps and social media are supported.
Hotspot is supported, but support cannot be guaranteed for all devices.
For dual-SIM phones, we strongly recommend inserting the SIM card into slot 1.
