Frequently Asked Questions about the Hong Kong SAR China eSIM

Everything you need to know about the Hong Kong SAR China eSIM.

01

When does my data plan start?

This plan's days start when the eSIM first connects to a network in its coverage area, not when you buy or install it. Some other Hong Kong SAR China plans start differently. Each plan's page shows its rule under Activation.

02

Can I make phone calls and send messages with the eSIM?

Most Hong Kong SAR China plans are data-only, with no phone number for calls or texts. Plans marked Call include a phone number, call minutes and text messages (SMS). On a data-only plan you can still call and message over apps like WhatsApp.

03

When will I receive my eSIM?

Once you purchase an eSIM, you will receive it immediately to your email address. You then scan the QR code to install the eSIM. If you have not installed, activated or used your eSIM, you can ask us to review a refund within 30 calendar days of purchase, when the order is linked to your Roamify account email. See our refund policy for more information.

04

Can I keep my WhatsApp number?

You don't need to do anything to keep your WhatsApp number. You'll automatically keep your number, contacts and conversations.

05

What is the network speed of the eSIM?

The Roamify eSIM offers maximum speed coverage. But bear in mind that in some areas of limited coverage there may be a lower speed connection.

06

Do I have to activate data roaming on my device?

Yes. To ensure that your eSIM gets the best coverage, you must turn on data roaming on your mobile settings. This will not incur any additional charges, as long as you have already set up the eSIM.

07

Will my eSIM have a local IP address in Hong Kong SAR China?

Not always. This plan connects through a roaming partner, so websites and apps may see an IP address registered in another country rather than in Hong Kong SAR China. This is normal for travel eSIMs and does not change your data allowance, speed or coverage. If a service requires a local IP address, such as some banking apps or regional streaming catalogues, connect through a local network or use a VPN set to Hong Kong SAR China.

08

What do I do if I delete or lose my eSIM's QR code?

If you cannot find the code, please contact our 24/7 customer support team at support@getroamify.com or our online chat function. We will resend the code to your email.

09

What happens if I use up my data or my days of validity?

On Hong Kong SAR China Unlimited plans, full speed lasts up to 1 GB, then data is slowed to 5 Mbps, not cut off. On Hong Kong SAR China plans with a fixed amount of data, data stops or is slowed once it is used up, depending on the plan. Some of them can be topped up with more data. Each plan's page shows its rule under Fair use policy. When the plan's days run out, your eSIM stops working and you lose its internet connection.

10

What eSIM data plan should I choose for Hong Kong SAR China?

You can choose variable plans as shown above. You can contact us at any time if you're not sure which plan is best for you.

11

Will the connection speed be reduced?

On Hong Kong SAR China Unlimited plans, full speed lasts up to 1 GB, then data is slowed to 5 Mbps, not cut off. If your connection seems slower than that, contact us by chat and we will check it.

12

Can I renew or extend the data on my eSIM?

Yes, you can do so by logging into your customer panel on the Roamify website. You will find the data plans you can purchase there. Once you've made your purchase, it will be activated immediately on the eSIM you have linked.

13

Can I share data with other devices?

Yes, you can share data with other devices. You can do this by activating the hotspot on your device.

14

How do I set up the eSIM on my device?

Once you make your purchase, we will send you an email with precise instructions to install your eSIM in two ways: by scanning the QR code or by copying and pasting the manual installation codes. To install with the first option, it is essential that the QR code is printed or on another device. Otherwise, you can follow the manual installation instructions for your Roamify eSIM. If your device is iOS, go to Settings → Cellular → Add eSIM and scan the QR code or paste the manual installation codes sent to your email. Then follow the on-screen instructions and choose your new eSIM as the line for mobile data. If your plan includes calls or texts, choose the Roamify eSIM as the line for those too. On a data-only plan, keep your physical SIM as the line for calls and texts. If your device is Android, follow the instructions we will email you to install your Roamify eSIM. When you are in Hong Kong SAR China, select your Roamify eSIM for mobile data and turn on data roaming for it. At Roamify, we want to make setting up your eSIM as easy as possible. For this reason, all our eSIM products come with complete instructions for easy setup. If you have any questions or need help, don't hesitate to contact our customer support team. We will be there for you 24/7.

15

When should I set up my eSIM?

You can install this plan a day or two before you travel, over Wi-Fi. Its days start only when it first connects to a network in its coverage area. When you are in Hong Kong SAR China, select the Roamify eSIM for mobile data and turn on data roaming for it. An installed eSIM is generally no longer refundable. See our refund policy.

16

How can I check how much data I have left?

To check your remaining data, log in to our web app with the access details we emailed you when you made your purchase. You can also check your data use in your device's mobile data settings.

17

How many times can I use my eSIM card?

Your eSIM can only be activated on one device. If you delete the eSIM from your device, you will not be able to reuse it. You cannot scan the QR code on two devices.

18

How can I delete the Roamify eSIM once I've used my data?

You don't need to delete the eSIM. But if you want to, please see how to delete eSIM on iOS and Android.

19

Can I use my (physical) SIM card and Roamify eSIM at the same time?

Yes. Choose the Roamify eSIM as the line for mobile data in your device settings. On a data-only plan, keep your physical SIM for calls and texts; if your plan includes calls or texts, choose the Roamify eSIM as the line for those too. If data roaming stays on for your physical SIM, your home network provider may charge roaming fees, so turn it off for that line.

20

How do I get a refund?

Most unused eSIM purchases are eligible for a refund review when you send your request within 30 calendar days of purchase. To qualify, the eSIM must not be activated, installed, or consumed, and the order must be linked to your Roamify account email. Once an eSIM has been activated or installed, or has recorded data usage, it generally cannot be refunded. Please see our eSIM Refund Policy for the full terms.

Cross-Harbour Connectivity in Hong Kong

Hong Kong, or 香港 as it's known locally, is a vibrant metropolis where urban adventures meet stunning natural landscapes. Travellers flock to iconic districts like Central, bustling with skyscrapers and business hubs; Tsim Sha Tsui, known for its waterfront promenade and cultural spots; and Mong Kok, a hotspot for shopping and street food. A typical journey might include riding the Star Ferry across Victoria Harbour or ascending Victoria Peak for panoramic city views. Amidst the city's fast-paced rhythm, staying connected is essential for navigating the efficient public transport system and discovering hidden gems.

Hong Kong generally boasts robust mobile connectivity, particularly in urban centres such as Central and Kowloon, where coverage is strong and reliable. However, as you venture into the New Territories or towards the outlying islands, including Lantau and Lamma, signals can waver, particularly in more remote or mountainous areas. While the MTR provides decent coverage underground, occasional signal drops can occur, especially on longer stretches between less populated stations.

Before you fly

Before landing in Hong Kong, ensure your eSIM is set up and ready to activate upon arrival. It's wise to download essential maps and any travel apps beforehand to mitigate any connectivity gaps during transit. Once in the city, expect smooth activation and seamless internet access, particularly in the urban sprawls where you'll spend much of your time exploring.

Using an eSIM in Hong Kong SAR China

Answers to the questions travellers actually ask about staying connected in Hong Kong SAR China.

3 questions

Can I use WhatsApp with an eSIM while traveling from Hong Kong to Macau via the Hong Kong-Zhuhai-Macao Bridge?

Only with a plan that also covers Macau: our Hong Kong plans cover Hong Kong only, so on one of them your phone has no mobile data, for WhatsApp or anything else, once you reach Macau. Our Asia plan lists both Hong Kong and Macau, so one eSIM works on both sides of the bridge. Its page lists every destination it covers. Or add our Macau plan next to your Hong Kong eSIM. In Macau, select that eSIM for mobile data and turn on data roaming for it.

Is there eSIM coverage in rural areas like Sai Kung during a day trip?

Yes, wherever H3G has signal. Sai Kung is part of Hong Kong, so your Hong Kong plan covers it, and H3G is the one network our Hong Kong plans use, on 4G, LTE and 5G. In the hills and bays of Sai Kung East Country Park we cannot say where it reaches, so download a trail map before you set off.

Will my eSIM switch networks automatically when traveling between Hong Kong and Shenzhen via Lo Wu station?

A Hong Kong plan cannot: it covers Hong Kong only, so once you pass Lo Wu into Shenzhen it has no data. For the whole trip on one eSIM, our Asia plan takes in both Hong Kong and mainland China. Its page lists every destination it covers. Or keep your Hong Kong plan and add our China Mainland plan as a second eSIM. In Shenzhen, select that eSIM for mobile data and turn on data roaming for it.
