Data Roaming Frequently Asked Questions (FAQ)
- Q1: What is the "Data Roaming Day Pass Easy Version"?
  A1: This is a daily fee data roaming service that allows you to use mobile data in over 170 destinations without needing to change your SIM card or rent a Wi-Fi egg. The service is charged on a daily basis, with prices divided into four charging zones (Zone A - Zone D) based on the destination.
- Q2: How is the daily roaming fee calculated?
  A2: The daily fee ranges from HK$88 to HK$178, depending on the destination you are in on that day.
  - Zone A (HK$88): Mainland China, Macau
  - Zone B (HK$88): Japan, Taiwan, South Korea, Thailand, Singapore, and other popular regions
  - Zone C (HK$138): Specified regions in Europe and America (e.g., USA, Canada, and European)
  - Zone D (HK$178): All other global regions and Aircraft Roaming.
- Q3: What are the speed limits for the roaming data?
  A3: The roaming Mobile Data available is 500MB per day (calculated based on local time), after which the data transmission speed will be capped at 512kbps.You can still maintain basic network connectivity until the next local day begins.
- Q4: How will I be charged if I travel across multiple destinations within the same day?
  A4: If you visit multiple destinations within the same "roaming day," a separate daily fee will be charged for each destination. For example, visiting both the South Korea and Japan on the same day will result in two Zone B daypass easy version charges.
- Q5: I forgot to purchase the "Pre-purchase Data Roaming Day Pass Package." Will the "Data Roaming Day Pass Easy Version" be activated automatically?
  A5: Yes. If you are a SUN Mobile customer and have activated the data roaming service, the "Data Roaming Day Pass Easy Version" is enabled by default. When you turn on data roaming and start using data in a designated destination, the daily fee will be automatically activated, ranging from HK$88 to HK$178 depending on your roaming destination.
- Q6: Will using data overseas result in "bill shock"?
  A6: No. The "Data Roaming Day Pass Easy Version" uses a fixed daily fee model. All charges are calculated on a daily basis, with the daily fee being HK$88 to HK$178 (depending on the destination). This effectively prevents "bill shock."
- Q7: Will I be charged if I do not use any data on a particular day?
  A7: No. The daily pass operates on a "pay-as-you-use" model. The daily fee is only charged when you generate data usage in a designated roaming destination. If there is no data usage, there is no charge.
- Q8: How is a "day" calculated?
  A8: The calculation of a "day" is based on the local time of the designated roaming destination, from 00:00 to 23:59. Please note that there may be a time difference compared to Hong Kong time.
- Q9: If I only need to use the service for one day, do I need to cancel it?
  A9: The day pass service charges you only for the days you use it. If no data is used, no fees will be incurred. However, to be safe, it is recommended that you turn off the "Data Roaming" function in your phone settings when you do not need it. This prevents background apps from automatically updating and accidentally generating usage and charges.
