You step off the plane at Hong Kong International (HKG) and the first thing you notice is the efficiency. The Airport Express is signposted clearly, the Octopus card machines are ready, and the city is already moving. Before you join it, you need data. Maps, WhatsApp, a quick check on your hotel booking. That is where a travel eSIM makes the arrival simple.

Slashtel sells a Hong Kong eSIM that you install before you fly. The QR code arrives by email within a minute. You pay from $2.29, with no contract and no local address needed. It is data only, so no local number, calls or SMS, but WhatsApp calls work over data. Hotspot is allowed, and top-ups are done online on the same eSIM. Your days start counting only when it first connects in Hong Kong.

Who goes and why

UK travellers often pass through Hong Kong on a stopover or a short city break. You might have a few days between flights, enough to ride the Star Ferry, eat in Kowloon and see the skyline from Victoria Peak. A short plan usually covers the whole stay, because you are not here long enough to burn through much data. The eSIM keeps you online from the moment you land, without hunting for a local SIM at the airport.

Indian travellers come for business trips, shopping and stopovers. You might have meetings on Hong Kong Island, a day of shopping in Tsim Sha Tsui, then a flight onwards. Your Indian SIM stays in the phone for bank OTPs and calls home, while the eSIM handles data. That means you can keep your number active and still use maps, email and WhatsApp without roaming charges.

How much data for this trip

Data Duration What it covers
1GB 3-5 days Maps, WhatsApp text, light email. No video.
3GB 1 week Maps, WhatsApp calls, occasional social media.
5GB 2 weeks Maps, WhatsApp video, some music streaming.
10GB 1 month Daily use including video and video calls.

For a short stopover of 3 to 5 days, 1GB is often enough if you stick to maps and messaging. For a week of city breaks and business, 3GB gives you comfortable headroom. If you are staying two weeks or more, or you plan to stream and take video calls, choose 5GB or 10GB.

Two practical notes for Hong Kong

The Octopus card covers the MTR, buses, ferries and many shops. You can tap it on the MTR, on buses, on the Star Ferry and in convenience stores. It is the easiest way to get around without carrying cash. Your eSIM handles the data, the Octopus handles the transport and small purchases.

Many travellers pass through on a stopover, so a short plan often covers the whole stay. If you are here for a few days between flights, you do not need a large data bundle. A 1GB or 3GB plan will see you through maps, messages and the occasional upload. Save the bigger plans for longer trips or if you plan to work remotely.

Install before you fly

Install your eSIM at home while you have Wi-Fi. Our installation guide walks you through the steps for iPhone and Android. Your home SIM stays in the phone for calls and OTPs, so you do not lose access to your bank or your family. If you are keeping an Indian SIM active, read our guide on keeping your Indian SIM active abroad. It explains how to avoid roaming charges while still receiving SMS.

Questions, answered

Will my phone work with a Hong Kong eSIM?

Your phone must be unlocked and eSIM compatible. Most recent iPhones and many Android phones support eSIM, but check your settings. If your phone is locked to a network, the eSIM will not install.

Can I keep my Indian or UK SIM active for bank OTPs?

Yes. Your physical SIM stays in the phone and your eSIM runs alongside it. You can receive SMS OTPs on your home number while using the eSIM for data. Just make sure data roaming is switched off on your home SIM to avoid charges.

How much data do I need for a 1 to 2 week trip?

For a 1 week trip, 3GB is usually enough for maps, WhatsApp calls and occasional social media. For 2 weeks, 5GB gives you room for WhatsApp video and some music streaming. If you plan to work or stream daily, choose 10GB.

Should I install the eSIM before I fly?

Yes. Install it at home while you have Wi-Fi, then leave it switched off until you land. The QR code arrives by email within a minute of purchase. When you arrive in Hong Kong, turn the eSIM on and it will connect automatically.

Will I have coverage on Hong Kong Island, Kowloon and Lantau?

You will get coverage on a major local network across Hong Kong Island, Kowloon and Lantau, including the MTR and major shopping areas. Coverage can be weaker in some remote parts of Lantau or inside deep buildings. The eSIM is data only, so no calls or SMS, but WhatsApp calls work over data.

Can I use hotspot to share data with my laptop?

Yes, hotspot is allowed on all our Hong Kong plans. You can share your data with a laptop or another device. Just remember that using hotspot will use your data faster.

What is the best eSIM for Hong Kong SAR China?

For most trips a 5GB to 10GB data eSIM valid for 30 days is the right size: Slashtel's 5GB plan for Hong Kong SAR China is $6.39 on csl, SmarTone and 3. Install it before you fly, keep your home SIM on for calls and bank texts, and top up the same eSIM if you run low.

Do I need a Hong Kong SAR China SIM card or an eSIM?

If your phone supports eSIM, an eSIM is simpler than a local SIM card: nothing to collect at the airport, no passport registration, and your home SIM stays in the phone for calls and OTP texts. A physical SIM only makes sense for long stays where you need a local phone number.

How much does an eSIM for Hong Kong SAR China cost for a week?

From $2.29 for 1GB valid 7 days, as of 9 October 2026. Longer trips: two weeks from $4.29 (3GB), one month from $4.49 (3GB).

What is the cheapest data per GB for Hong Kong SAR China?

$0.67 per GB on the 50GB plan (30 days, $33.69). Bigger plans usually cost less per GB, so buy the size you expect to use.

Which networks does a Hong Kong SAR China eSIM use?

csl, SmarTone, 3 and csl/1010, with speeds up to 5G where available. The eSIM picks the strongest network automatically.

Does the Hong Kong SAR China eSIM include a phone number?

No. Slashtel eSIMs are data only, with no local number, calls or SMS. WhatsApp and other internet calls work, and your home SIM can stay on for calls and OTP texts.

When does the Hong Kong SAR China eSIM start counting days?

Validity starts when the eSIM first connects to a network in Hong Kong SAR China, not when you buy it, so you can buy and install it before you travel.

How do I install the Hong Kong SAR China eSIM?

After payment Slashtel emails a QR code within a minute. Scan it in your phone settings while on Wi-Fi at home, then switch on data roaming for the eSIM when you land.

Will my phone work with a Hong Kong SAR China eSIM?

Your phone must support eSIM and be carrier-unlocked. Dial *#06#: if an EID appears, the phone supports eSIM.

Can I use hotspot with the Hong Kong SAR China eSIM?

Yes. Hotspot and tethering are allowed on Slashtel eSIMs.
