Hong Kong eSIM FAQ
How much is a Hong Kong eSIM for a week?
Standard use, about 1GB a day, costs US$12.10 on the 10GB, 30 day plan; light use (300MB a day) US$5.70 (3GB, 15 days) and heavy use (2GB a day) US$19.50 (20GB, 30 days).
How much is a Hong Kong eSIM for two weeks?
Standard use, about 1GB a day, costs US$19.50 on the 20GB, 30 day plan; light use (300MB a day) US$7.80 (5GB, 30 days) and heavy use (2GB a day) US$38.20 (50GB, 30 days).
Does the Hong Kong eSIM have 5G?
Yes: all two of its networks in Hong Kong, csl and SmarTone, run 5G. 5G needs a 5G phone and a 5G signal where you are.
Which networks does the Hong Kong eSIM use?
It connects to csl (5G) and SmarTone (5G), and the eSIM uses whichever of them has the best signal where you are.
Which regional eSIM also covers Hong Kong?
Two regional eSIMs cover Hong Kong as well: the Asia eSIM from US$4.10 (up to 20 countries) and the Global eSIM from US$11.90 (up to 129 countries). Each covers several countries on one plan, handy if the trip also takes in China or Japan.
Can I share the Hong Kong eSIM data by hotspot?
Yes, on the daily plans, from US$3 a day; hotspot use counts toward the same daily allowance.
When do the days start on the Hong Kong eSIM?
On first connection in Hong Kong, not at purchase or install. Install it on wifi before you fly, up to 180 days after buying. The 100MB (7 days) plan is an exception: its validity starts the moment you install it, not on first connection, so install it only when you are ready to start using the data.
Can I make calls with the Hong Kong eSIM?
No, it is data only, with no Hong Kong number: WhatsApp and FaceTime calls work over the data.
Where does the Hong Kong eSIM connect to the internet from?
From Singapore, so apps may see you there rather than in Hong Kong, which mostly matters to banking and streaming.
Heading somewhere else?
One eSIM can cover a whole region, handy for multi-country trips.
