- The activation time of this service is after 8pm the following day. Customers are required to select China Mobile HK or CSL as mobile service operator when they are traveling in Hong Kong, select China Mobile or China Unicom as mobile service operator when they are traveling in Mainland China.

- When customer’s remaining local data usage reaches 1GB, 500MB & 50MB in current billing month, an automatic SMS alert reminder will be sent. Once the remaining local data usage is consumed, local data / roaming data will be barred. Customers may unbar and purchase additional data. Customers may also unbar and pay for additional data per KB. In order to safeguard customers, the maximum charge for additional data is capped at $500 over and above customer’s monthly plan charges, (except Mobile Data Monthly, Blackberry Mobile Email Service & CTM Wi-Fi Usage). When this charge ceiling is reached, data access speed will automatically be adjusted to not less than 256kbps. While roaming, the customer is required to pay for all related data service roaming charges based on the individual charges of roaming network operators. The actual data transmission speed may vary due to certain circumstances such as the current internet environment, the computer hardware used, software(s) installed and used, the number of concurrent users, the location, the speed of the website(s) and other factors.
