Why Get an eSIM for Hong Kong?
- Great for stopovers. Hong Kong is a major hub, and a short plan keeps you online for a day in the city.
- Navigate the MTR and ferries with live route planning.
- Keep your number while the eSIM handles data.
- Much cheaper than roaming with most home carriers.
How to Choose a Hong Kong eSIM
Trip length
Hong Kong trips range from a single-day stopover to a week or more. egoViet's Hong Kong eSIM includes very short options, so pick one that covers your stay plus a spare day. egoViet plans can't be topped up, so it is better to size up than to run short. If your high-speed data does run out, you stay online at a basic speed of around 128 kbps, enough for messaging.
How much data you use
Maps, MTR apps, and messages use little data. Video calls and streaming on long ferry rides use much more. Here is a guide to how much data you need when you travel.
Where you are going
For Hong Kong alone, the Hong Kong eSIM is the best value. If you are also visiting Japan, Taiwan, Korea, or Southeast Asia, see the Asia eSIM below.

Visiting Macau or More of Asia?
Hong Kong and Macau are separate mobile markets, so a Hong Kong eSIM won't work in Macau. egoViet has a separate Macau eSIM, and the Asia eSIM covers both Hong Kong and Macau along with Japan, Korea, Taiwan, and Southeast Asia.
Here is how country and regional eSIMs compare.
Which Hong Kong eSIM Plan Is Right for You?
| Your trip | Our pick |
|---|---|
| Stopover of a day or two | A short daily plan |
| Long weekend in the city | A small fixed plan or 1 GB/day for 3–4 days |
| A week with hikes and island trips | A 7-day plan with 5–10 GB |
| Hong Kong plus a day trip to Macau | Asia eSIM, or a Hong Kong eSIM plus a Macau eSIM |
| Hong Kong plus Japan, Taiwan, or Southeast Asia | Asia eSIM |
How to Set Up Your Hong Kong eSIM
- Check your phone is eSIM-compatible and carrier-unlocked. See our eSIM compatibility list.
- Buy your plan. The QR code arrives by email within minutes.
- Install it at home on Wi-Fi with our installation guide.
- When you land in Hong Kong, switch the eSIM on, set it for mobile data, and turn on data roaming for that line. Keep data roaming off on your home SIM.
Tips for Staying Connected in Hong Kong
- Get an Octopus card or use a phone wallet for the MTR, buses, ferries, and convenience stores.
- Check the weather alerts. During typhoon season (roughly June to October), the Hong Kong Observatory app shows warning signals that affect transport.
- Signal is good on most trails, but download offline maps for Lantau and the outlying islands just in case.
- Mainland China is different. A Hong Kong eSIM won't work across the border. Here is what to know about eSIMs for China.
- Need to call? egoViet eSIMs are data-only, so use WhatsApp or FaceTime. Here is how calling works with a data-only eSIM.
