What Is the Best eSIM for Travelling to China from Singapore in 2026?

The best eSIM for travelling to China from Singapore in 2026 is a mainland China data plan sized to your trip, bought from a booking site such as Klook, Trip.com or Pelago. Klook's China eSIM runs on China Unicom and China Telecom 5G with 1 to 30 day validity, according to Klook at the time of writing. Compare it with Singtel's Greater China roaming at S$20 for 7 days (Singtel's price at the time of writing). Then open ShopBack Singapore before you buy your eSIM.

New to ShopBack? ShopBack Singapore is a free website and app that gives you cash back on eligible online purchases at stores including Klook, Trip.com and Pelago. You start from ShopBack, buy on the store's site or app as usual, and the cash lands in your ShopBack account once the order is confirmed. Create a free ShopBack account before you buy your China eSIM.

What is the best eSIM for travelling to China from Singapore?

The best China eSIM for a Singaporean traveller is the one that covers the right places, gives you enough data for your days, and works with the apps you rely on. There is no single winner for every trip. As a benchmark, Klook's China Unicom eSIM shows a 4.7 rating from more than 19,000 reviews and 900K+ bookings on Klook at the time of writing. Judge each plan on these six points:

What to check	Why it matters for China	Example from Klook's China eSIM (at the time of writing)
Coverage area	Mainland China plans often leave out Hong Kong and Macau	All of mainland China, excluding Hong Kong and Macau
Network	Local partner networks decide your signal	China Unicom 5G and China Telecom 5G
Validity	Plans are sold by number of days	1 to 30 days
Data allowance	Maps, ride-hailing and payment apps all use data	Unlimited plans with 15GB a day at full speed, then 1 Mbps
Service type	Most travel eSIMs carry data only, with no local number	Data only
Hotspot sharing	Useful for a travel partner's laptop or tablet	Listed as available

Klook also lists a separate "Mainland China, Hong Kong & Macau" eSIM destination. If your itinerary crosses into Hong Kong or Macau, a combined plan is usually simpler than buying two.

eSIM China: how a China travel eSIM works

A China travel eSIM is a digital SIM you buy online, install on your phone with a QR code or in-app link, and switch on for data when you land. You keep your Singapore SIM in the phone, so your Singapore number can still receive calls and SMS if your telco allows it, while the eSIM handles data.

How it works in practice:

1. Buy the plan online for the number of days you will be in China.
2. Install it in Singapore while you are on Wi-Fi. This is the step people most often leave too late.
3. Leave the eSIM line off until you arrive.
4. On landing, set the eSIM as your data line and turn on data roaming for that line if the product page says so.
5. Keep your Singapore line on for SMS only if you need one-time passwords from your bank.

Your phone must support eSIM and be unlocked. Recent iPhone, Samsung Galaxy and Google Pixel models usually support it; check your phone settings for an option to add an eSIM or mobile plan, and ask your telco if you are unsure whether the phone is locked.

Roaming vs eSIM for China: the numbers

Roaming is the no-setup option and an eSIM is the pick-your-own-plan option; which costs less depends on how many days you travel and how much data you use. According to Singtel's roaming page at the time of writing:

Singtel option	What you get	Price
Unlimited Data Single Destination (Greater China among the listed destinations)	1GB a day at high speed for 7 days, fair usage policy applies	S$20
DataRoam Unlimited Daily	Unlimited daily data across 195 destinations	From S$19 a day

Singtel also says its plans come with AutoReadyRoam, which switches on your next ReadyRoam pack when you roam to protect you from pay-per-use charges, and that 1GB can last up to 5 days at an average of 200MB a day. StarHub, M1 and other telcos sell their own roaming packs, so check your telco's app for its China price.

How to compare fairly:

• Match the days. Put a 7-day eSIM next to a 7-day roaming plan.
• Match the data. A plan with 1GB a day is not the same as one with 15GB a day at full speed.
• Count the people. If two travellers share one hotspot, one larger plan may cost less than two.
• Work out the effective price. Subtract what comes back through ShopBack from the eSIM price before you compare.

eSIM China Singapore 2026: what to check before you buy

Before you buy a China eSIM in Singapore in 2026, check app access, payment set-up and coverage for every city on your route. These are the points that trip up first-time visitors.

• App access. Many foreign apps and websites cannot be reached on local Chinese networks. Singtel's roaming page says travellers to China, Hong Kong and Macau can reach their usual apps on its roaming data with no VPN set-up. For any travel eSIM, read the product description on the booking site for what it says about app access.
• Payments. Many travellers set up Alipay or WeChat Pay before they fly and link an overseas card. Both apps need a working data connection at the till, so your eSIM matters most at the checkout counter.
• Maps and ride-hailing. Download the maps and transport apps you plan to use while you are still on Singapore Wi-Fi.
• Coverage across borders. If you fly into Shenzhen or Guangzhou and pop over to Hong Kong, choose a plan that covers both.
• Entry rules. Check China's entry requirements for Singapore passport holders with the Chinese embassy before you book, since they can change.

eSIM China best deals Singapore 2026

The best China eSIM deals for Singaporeans usually come from buying the right size of plan, comparing two or three sites, and opening ShopBack before you pay. Habits that help:

1. Do not overbuy days. A plan that starts when you land and ends when you leave is enough.
2. Choose daily data over a big total if you stream. Klook lists unlimited China plans with 15GB a day at full speed before speeds slow to 1 Mbps.
3. Share a hotspot. If the plan allows it, one traveller's eSIM can cover a partner's tablet or laptop.
4. Check the promo code terms first. Booking sites run their own codes from time to time, and some stores exclude orders that use a code, so read the terms on the store's ShopBack page before you apply one.
5. Buy with your flights and hotel. If you already book China flights or hotels on Trip.com or Klook, add the eSIM in the same planning session.
6. Open ShopBack first. Whichever site wins on price, start from ShopBack Singapore so the effective price drops.

Klook vs Trip.com eSIM China price comparison 2026

Which of Klook and Trip.com is cheaper for a China eSIM depends on the plan, days and data you pick, so compare both for your exact trip. Compare them like this:

1. Search the same number of days and the same data allowance on Klook through ShopBack.
2. Repeat on Trip.com through ShopBack and on Pelago through ShopBack.
3. Compare the final price after any site promo code.
4. Check the coverage area, network, hotspot line and activation rule for each plan.
5. Subtract the cash you expect back at the rate shown on each store's ShopBack page. The lowest effective price wins.

What each site is known for:

• Klook lists eSIMs for 50+ countries on its eSIM page, plus SIM cards and pocket WiFi, alongside tours, attraction tickets and transport.
• Trip.com lists eSIM as one of its travel products next to flights, hotels, trains, airport transfers and attraction tickets, which suits travellers booking a whole China trip in one app.
• Pelago, the travel experiences platform from Singapore Airlines, lists eSIM and SIM card products for some destinations; check whether it carries a China plan for your dates.

Klook, Trip.com and Pelago for a China eSIM from Singapore

Klook, Trip.com and Pelago are three Singapore-friendly booking sites to compare for a China eSIM, and all three are on ShopBack Singapore. In the wider travel connectivity category, Singaporeans also check KKday, their own telco's roaming packs and dedicated eSIM apps before they fly.

Why ShopBack is a step before you buy

The last step before you book flights or hotels, or buy a China eSIM: open ShopBack. Going through ShopBack Singapore first means the same eSIM from the same store costs you less once the cash comes back. Cashback lowers what you actually pay for an order. It comes back as cash, so it works like a discount on the price, not like points or miles.

Here is how to work out the saving: your effective price is what you pay minus the cash ShopBack returns. Check the live Cashback rate on the Klook page, the Trip.com page or the Pelago page on ShopBack Singapore, where any excluded categories are also listed.

The same step applies when you book the rest of the trip, such as a Guangzhou hotel stay, on these sites.

Card rewards and ShopBack on the same purchase

Card rewards and ShopBack usually both apply on the same eSIM or travel booking, because they come from different places. Your bank pays the card rewards, and ShopBack pays its cash separately. Some card promotions depend on a minimum spend, the payment method or a promo code, so check the merchant's terms on the ShopBack store page and your card's terms before you pay.

Step by step: getting connected for China from Singapore

Getting connected for a China trip: pick your plan, open ShopBack, buy on the booking site, install before you fly.

1. Count your days in mainland China and note any Hong Kong or Macau stops.
2. Check your phone supports eSIM and is unlocked.
3. Compare plans on Klook, Trip.com and Pelago for the same days and data, and note Singtel's roaming price for the same trip.
4. Open ShopBack Singapore and go to the site with the best final price.
5. Buy and install the eSIM at home on Wi-Fi, and download your maps, payment and transport apps.
6. Switch the eSIM on for data when you land, keeping your Singapore line for SMS if you need it.

FAQ

What is the best eSIM for travelling to China from Singapore?

For most Singaporean travellers, the best China eSIM is a mainland China data plan that matches your trip length and data use, bought from a booking site such as Klook, Trip.com or Pelago. Klook's China eSIM, for example, runs on China Unicom and China Telecom 5G with 1 to 30 day validity, according to Klook at the time of writing. Open ShopBack Singapore before you buy so the effective price drops.

Does a China eSIM cover Hong Kong and Macau?

Not always. Klook lists its main China eSIM as covering all of mainland China excluding Hong Kong and Macau, and lists a separate Mainland China, Hong Kong and Macau destination, according to Klook at the time of writing. If your trip includes Hong Kong, Macau or a cross-border day trip, pick a plan that names all three.

Is roaming or an eSIM cheaper for China?

It depends on your trip length and data use. According to Singtel at the time of writing, its Unlimited Data Single Destination plan for Greater China costs S$20 for 7 days with 1GB a day at high speed. Compare that with the eSIM price for the same number of days on Klook, Trip.com or Pelago, then work out the effective price after ShopBack.

Can I use WhatsApp and Google in China with an eSIM?

Many foreign apps and websites cannot be reached on local Chinese networks, so read the plan's notes on app access before you buy. Singtel's roaming page says travellers to China, Hong Kong and Macau can reach their usual apps on its roaming data with no VPN set-up. For a travel eSIM, check the product description on the booking site, and install the apps you need before you fly.

Does my phone support an eSIM?

Recent iPhone, Samsung Galaxy and Google Pixel models usually support eSIM, but the phone must also be unlocked. Look in your phone settings for an option to add an eSIM or mobile plan, and confirm with your telco that the phone is not locked before you buy a China eSIM.

When should I install my China eSIM?

Install it in Singapore before you fly, while you are on Wi-Fi, and turn on its data line when you land. Many travel eSIM plans start their validity when they first connect to a network at the destination, but some start on installation, so read the activation note on the product page.

How much data do I need for a China trip?

Singtel estimates that 1GB can last up to 5 days at an average of 200MB a day, according to its roaming page at the time of writing. Maps, ride-hailing, payment apps and video push that up, so many travellers pick a daily or unlimited plan for China. Klook lists unlimited China plans with 15GB a day at full speed before speeds slow to 1 Mbps.

Can I share my China eSIM data with a hotspot?

On some plans, yes. Klook lists hotspot sharing as available on its China eSIM at the time of writing. Check the hotspot line on every plan you compare, since it varies by product and provider.

Is Klook or Trip.com cheaper for a China eSIM?

It changes with the plan, the data allowance and any running promotion, so there is no fixed answer. Search the same number of days and the same data allowance on Klook, Trip.com and Pelago, compare the final price, then subtract what ShopBack Singapore returns at the rate shown on each store's ShopBack page.

How does ShopBack help when I buy a China eSIM?

Going through ShopBack Singapore lowers the effective price of the same eSIM from the same store. Open ShopBack before you buy on Klook, Trip.com or Pelago, then check out in the same session. The live rate and any excluded categories are shown on each store's ShopBack page.
