Share with your laptop
Hotspot is allowed on the plan selected above, so a second device can use the same data in a cafe or a hotel room.

Hong Kong travel data guide
A Hong Kong eSIM from RoamZivo is a prepaid data plan for Hong Kong that you install before you fly. Plans in Hong Kong run on csl and SmarTone, with 5G where the operator offers it. The eSIM is data only, so your own SIM stays in for calls and texts.
There are 19 plans to choose from. Data sizes run from 1 GB to 50 GB, validity from 1 to 30 days, and prices start at $1.99. Unlimited plans are listed too, each with its own fair use line. Hotspot sharing is supported on every plan. Top ups are available on the fixed data plans and go onto the same eSIM.
Visiting more than one country? The China, Hong Kong & Macao eSIM covers Hong Kong and 2 other countries on one plan, from $2.99. The Asia (14 countries) eSIM covers Hong Kong and 13 other countries on one plan, from $2.99. The Asia Pacific eSIM covers Hong Kong and 19 other countries on one plan, from $10.99. The Global eSIM covers Hong Kong and 126 other countries on one plan, from $18.99.
Your days start the first time the eSIM connects in Hong Kong, not when you buy, so you can install it at home days early. For a week of maps, messaging and social apps, most travellers are fine with 3 to 5 GB. Video calls or streaming need more, or an unlimited plan. Travel data in Hong Kong from RoamZivo arrives as a QR code by email, with a copy kept in your account.
Hong Kong FAQ
Does the eSIM work everywhere in Hong Kong?
It connects wherever csl and SmarTone have signal, which is the same network local customers use. The eSIM is data only.
When do my days start?
On the first connection in Hong Kong, not at purchase. The plan selected above (3 GB) runs for 1 day from that moment. You can install the eSIM at home and the clock stays still until you connect.
Do I get a local phone number in Hong Kong?
No. The eSIM is data only. Your own SIM stays in for calls and texts, and WhatsApp keeps working over the eSIM data.
Can I share data with my laptop?
Yes. Hotspot sharing is supported on the plan selected above, so your laptop or tablet can use the eSIM data through your phone.
Is 5 GB enough for a week in Hong Kong?
5 GB is enough for a week in Hong Kong for most people, covering maps, transport apps, messaging and social media. The 5 GB plans come as a one day plan or a 30 day plan, so choose the 30 day one for a week long stay.
Is the Hong Kong eSIM 5G?
Yes, the two networks on our Hong Kong plans, csl and SmarTone, are both listed as 5G, and the plans are labelled for 5G. Your phone has to support 5G to use it. Otherwise it connects on 4G.
Should I buy a Hong Kong plan or the Asia Pacific plan?
Buy the Hong Kong plan if you are staying in Hong Kong only, and consider the Asia Pacific plan if you are visiting several places on one trip. Check the regional plan's country list first, since not every destination is on it.
Can I install the eSIM during my layover?
You can, but it is better to install before you leave home. The eSIM needs WiFi to download, and a Hong Kong day plan only starts when it first connects to a network there, so setting it up early costs nothing.
Will my home SIM still receive texts?
Yes, your home SIM stays active for calls and texts if you leave it switched on. The Hong Kong eSIM handles data only. Turn off data roaming on the home SIM so it does not use data abroad.
Can I hotspot from a Hong Kong eSIM?
Yes, hotspot is allowed on all Hong Kong plans. On unlimited plans, the data your laptop uses counts toward the 1 GB or 3 GB of full speed for that day.
Can I top up instead of buying a new plan?
On some Hong Kong plans you can top up, and on others you cannot. The plan card shows whether top up is offered. If it is not, you can buy another plan when the first one ends.
How do I top up if I run low?
Open My eSIMs, pick this eSIM and choose a top up. It goes onto the same eSIM, so there is no new QR code to scan.
