Questions

Which networks does the Hong Kong eSIM use?

csl (5G) and SmarTone (5G). Which one your phone uses depends on the plan and on where you are.

Does the Hong Kong eSIM work on 5G?

Yes, 5G on csl and SmarTone. Your phone needs to support 5G; where there is no 5G signal, it uses 4G/LTE.

Will my phone work with the Hong Kong eSIM?

Yes, if your phone supports eSIM and is not locked to one carrier. Most iPhones from the XS and XR onwards do, as do recent Samsung Galaxy and Google Pixel models. Check yours in our list of eSIM phones.

Does the Hong Kong eSIM come with a phone number?

No. It is data only: no phone number, no calls or SMS. Your own SIM stays in your phone, so WhatsApp and iMessage keep working with your usual number.

How much data do I need for a week in Hong Kong?

About 0.7 GB a day covers maps, messages, social media and some video, so around 5 GB for a week. Our pick for one week: 5 GB · 30 days for $10.49.

What is the cheapest Hong Kong eSIM?

1 GB · 7 days for $3.69 is the lowest-priced plan. The lowest price per GB is 50 GB · 30 days at $0.89 per GB. A single day with 0.49 GB costs $2.29.

How long is the Hong Kong eSIM valid?

Plans run for 7, 15, 30 or 180 days. Day plans can be booked for 1 to 30 days.

When does my plan start?

When your phone first connects to a network in Hong Kong, not when you buy or install the eSIM. So you can install it at home before you travel.

Is there an unlimited Hong Kong eSIM?

Not at full speed. Day plans come closest: up to 10 GB a day at full speed, then 384 Kbps until the next day.

Can I use the Hong Kong eSIM as a hotspot?

Yes, your phone can share the connection with a laptop or a second phone. Everything you share counts against your plan. Whether a network limits sharing depends on the plan, so ask us before you buy if it matters. More in our hotspot guide.

Can I top up my Hong Kong eSIM?

Yes, on plans marked “Top-up possible”: add data under My eSIMs while the plan is still valid. No new eSIM needed.

What happens when I use up my daily data?

On day plans you get full speed up to the daily allowance. After that, the speed drops to between 384 Kbps and 1 Mbps, depending on the plan, until the next day.

Why do some apps think I am in Singapore?

Depending on the plan, your connection runs via Singapore. Websites and apps, such as banking or streaming services, may then treat you as being there.

Can I get a refund?

eSIM purchases are final. If something isn’t right, write to us in Help and we’ll take care of it.
