- You can scan the QR and install the eSIM before you travel. Days start counting when you arrive in Hong Kong, in 24-hour periods from first use, and you must activate it within 60 days of purchase.
- Moderate use is about 1.5 GB a day: 10 GB is enough for 5 days. If you don't want to count data, or you watch a lot of video, pick Unlimited.
- Every plan runs on 5G on 3HK and CMHK and lets you check your remaining data, but works in Hong Kong only. If you visit Macau or Shenzhen, choose China Hong Kong Macau.
- Every plan allows hotspot sharing. They are data only, with no phone number for calls or SMS, and cannot be topped up. GB plans continue at 128 kbps after the data is used up.
