About this eSIM

Three systems on one plan

Hong Kong, Macau and mainland China have separate mobile markets, currencies, immigration controls and internet rules, even though you can cross between them in under an hour. In Hong Kong the eSIM can use csl, 3 or SmarTone; in Macau, CTM; and on the mainland, China Mobile, China Unicom or China Telecom. Your phone will show the network name changing as you cross.

Coverage is not the issue. Hong Kong has some of the densest mobile networks in the world, including in the MTR, and Macau's casinos and old town are well served. On the mainland, the big cities, high-speed rail lines and main tourist sites all have strong 4G and widespread 5G.

This plan is most useful when you cross more than once. A typical trip might land at Hong Kong, spend a day in Macau, take the train to Guangzhou or Shanghai and return through Shenzhen, and buying separate plans for each leg would mean three installs and three allowances. Here the same eSIM simply moves to the next partner network each time, and the airport arrival is the same whether you land at Hong Kong, Pudong or Baiyun: switch off airplane mode as you taxi in and give it a minute.

How the internet changes at the boundary

In Hong Kong and Macau, the internet is broadly open, and Google, WhatsApp, Instagram and Western news sites work normally on wifi and mobile data. On the mainland, those services are blocked on local connections, including hotel wifi and Chinese SIMs.

Travel eSIMs in mainland China normally work by roaming, with traffic leaving the country through a gateway abroad, often Hong Kong. eSIMDB and Yesim both explain that this is why blocked services usually load on a roaming eSIM without a VPN. It still depends on where a plan's traffic exits, and Yesim notes that some services, including some AI tools and TikTok, can restrict Hong Kong IP addresses. Test your key apps as soon as you cross and keep a VPN installed as a backup, because downloading one in the mainland is difficult.

Paying and getting around

Each territory has its own way of paying. In Hong Kong, the Octopus card, now also available in Apple Wallet, covers the MTR, buses, ferries and many shops. In Macau, prices are in patacas, but Hong Kong dollars are widely accepted. On the mainland, mobile payment is the norm, and many places are reluctant to take cash or foreign cards directly. Alipay and WeChat Pay both let visitors link a foreign Visa or Mastercard, according to Travel Weekly Asia, and Alipay also gives you DiDi taxis and metro QR codes in many cities.

For maps, Google Maps is reliable in Hong Kong and Macau but has poor data on the mainland. Use Apple Maps or Amap across the border.

Before you fly

Set up Alipay and link your card at home, because verification texts go to your normal number, which stays in the phone. Install a VPN and test it before you travel. Download Amap, and save your hotel addresses in Chinese characters to show taxi drivers.

Check entry rules for your passport: mainland China has expanded visa-free entry for many nationalities, including the UK and Canada from February 2026, and offers a 240-hour visa-free transit for eligible travellers who arrive from one country and leave for another. Note that Taiwan is not part of this plan.

Unlimited runs at full speed up to a fair-use limit, then continues slower.

Before you buy

Important to know

  • This is a data-only eSIM. It carries no calls or SMS on its own number.
  • Your existing number stays on your primary SIM, so calls and verification texts keep working.
  • Your phone must support eSIM, and some carrier-locked phones cannot install one.
  • Signal varies with location, terrain, congestion and your handset. Dense urban areas are consistently better served than remote ones.
  • 5G only works where the host network has deployed it and your phone supports it. Everywhere else it falls back to 4G LTE.
  • Unlimited plans run at full speed up to a fair-use limit, then continue at a reduced speed. Read the fair usage policy

Frequently asked questions

Does an eSIM work in Greater China?

Yes. Your Greater China eSIM connects automatically the moment you arrive, with no roaming fees and nothing to set up at the airport. Coverage runs on 4G LTE and 5G where the network has rolled it out, and falls back to 4G elsewhere.

Do I get 5G in Greater China?

Yes, where it has been deployed. 5G runs on The local networks we use in Greater China, and your eSIM uses it automatically on a 5G-capable phone, dropping back to 4G LTE outside covered areas. No country is covered everywhere, so 5G availability varies by location.

Will WhatsApp and Google work when I cross from Hong Kong into mainland China?

Usually, yes. Travel eSIMs in the mainland roam on local networks but send data out through a gateway abroad, often Hong Kong, so blocked services typically load without a VPN. It depends on where a plan's traffic exits, and some apps restrict Hong Kong IP addresses. Test your key apps right after crossing and keep a VPN installed as a backup.

Does the Greater China eSIM cover Taiwan?

No. This plan covers mainland China, Hong Kong and Macau only. Taiwan has separate mobile networks and is not on the covered list. If your trip continues to Taipei, you will need a separate plan or a wider Asia plan that includes Taiwan.

Is there signal in the Hong Kong–Zhuhai–Macau Bridge tunnel?

Expect a short gap. The bridge is 55 km long and includes a 6.7 km undersea tunnel, where your phone may lose service for a few minutes. Shuttle buses take about 40 minutes for the whole crossing, and you will reconnect on the bridge sections and when you arrive at the Macau or Zhuhai port, where the phone switches network.

Can I pay with Apple Pay or a foreign card in mainland China?

Not easily in most places. Mobile payment through Alipay and WeChat Pay is the norm, and many smaller shops and restaurants do not take foreign cards directly. Both apps let visitors link a foreign Visa or Mastercard, so set one up before you travel. In Hong Kong and Macau, cards and the Octopus card are widely accepted.

Which maps app should I use in mainland China?

Use Apple Maps on an iPhone or Amap on either platform. Google Maps has poor and often offset map data in the mainland, so walking directions and pins can be wrong. Amap has an English interface, accurate public transport routing and is widely used by locals. In Hong Kong and Macau, Google Maps works well.

How much data do I need for 7 days in Greater China?

For 7 days in Greater China, Viasimo sells 1 GB for $2.29 and unlimited data for $25.99. Our sizing recommendation, not a measurement: maps, messaging and the occasional lookup, about 1 GB a week; maps, social, photos and some browsing, about 3 to 7 GB a week. The data calculator on this site works it out from how you actually use your phone.

Know before you go

Greater China: what to know before you land

This plan covers mainland China, Hong Kong and Macau on one eSIM, which suits the common Hong Kong, Shenzhen, Guangzhou and Macau combination as well as longer trips to Shanghai or Beijing. All three have dense 4G and 5G. The real difference is the internet itself: Hong Kong and Macau are open, while the mainland sits behind the Great Firewall.

Crossing from Hong Kong to Shenzhen and Guangzhou

Most visitors cross into the mainland from Hong Kong at Lo Wu or Lok Ma Chau on the MTR East Rail line, or by high-speed train from West Kowloon. At West Kowloon you clear mainland immigration inside the station itself, in a Mainland Port Area, before boarding trains to Shenzhen Futian, Guangzhou South and beyond.

Around the land border, your phone may hop between Hong Kong and mainland networks, because the towers on each side are so close. Both are covered by this plan, so data keeps working either way, but the rules change with the network. On a Hong Kong network everything is open; on a mainland one, how blocked apps behave depends on the eSIM's routing.

Once you are clear of the border, cycle airplane mode if your phone is still clinging to a weak Hong Kong signal. Then check your key apps. In Shenzhen and Guangzhou, switch to Amap or Apple Maps and use Alipay for the metro and DiDi. For a day trip, remember that you need to carry your passport for both crossings.

Macau by ferry or the Hong Kong–Zhuhai–Macau Bridge

There are two main ways to get from Hong Kong to Macau. The first is the ferry from the Hong Kong–Macau Ferry Terminal in Sheung Wan or from the airport, which runs along the coast and the Pearl River estuary. The second is the Hong Kong–Zhuhai–Macau Bridge, which is 55 km long and includes a 6.7 km undersea tunnel. Shuttle buses run across it 24 hours a day and take about 40 minutes.

On both routes you may lose signal briefly, especially in the bridge tunnel, but the estuary is busy and close to land, so you will usually pick up a network again quickly. When you arrive at Macau, your phone switches to CTM.

In Macau, everything that works in Hong Kong works too. Casinos and hotels have strong indoor coverage, and the historic centre around Senado Square and the Ruins of St Paul's is well served. From Macau you can also walk across the Gongbei border into Zhuhai on the mainland, and the plan carries on there.

Beijing, Shanghai and the high-speed rail network

Many Greater China trips extend beyond the south to Shanghai, Beijing and Xi'an. All the big cities have strong 4G and 5G, and the high-speed rail network between them is generally well covered, with short drops in tunnels and in mountainous sections such as the routes into Sichuan and Guilin.

Train tickets are sold through the official 12306 app and website, which has an English version and accepts foreign passports, and through travel agencies. Book early around Chinese New Year, the May Day holiday and the National Day week in early October, when trains sell out.

Tourist sites like the Great Wall at Mutianyu or Badaling, the Terracotta Army near Xi'an and West Lake in Hangzhou all have mobile coverage. More remote landscapes, such as parts of Zhangjiajie, Jiuzhaigou or the Tibetan plateau, have patchier signal. Download Amap offline areas and save your hotel addresses in Chinese characters before you set off.

Length
10 days
Bases
4

When to go October to December is the most comfortable season, with dry, clear days; spring is humid and misty around Guilin, summer is hot with typhoon risk on the coast, and Chinese public holidays such as Golden Week in early October fill trains and sights.

  1. Day 1 Hong Kong

    Hong Kong: Central and Victoria Peak

    Ride the Peak Tram up to Victoria Peak and walk the Lugard Road loop for the view over the harbour. Come down to Central, take the Mid-Levels escalator through SoHo, and visit Man Mo Temple on Hollywood Road. In the evening, cross the harbour on the Star Ferry to Tsim Sha Tsui.

    Signal Excellent 5G on csl, SmarTone or 3 across Hong Kong Island and Kowloon, including the MTR and the Star Ferry.

  2. Day 2 Hong Kong

    Hong Kong: Kowloon markets and temples

    Visit Wong Tai Sin Temple and the Chi Lin Nunnery with the Nan Lian Garden next door. In the afternoon, explore Mong Kok's Ladies' Market, the flower and bird markets, then walk down Nathan Road to the Temple Street night market in the evening.

    Signal Strong throughout Kowloon, though the busiest market streets can slow data at peak times.

  3. Day 3 Hong Kong

    Lantau: the Big Buddha and Tai O

    Take the MTR to Tung Chung and the Ngong Ping 360 cable car to the Tian Tan Buddha and Po Lin Monastery. Walk the Wisdom Path, then take the bus down to Tai O fishing village with its stilt houses. Return to the city in the evening.

    Signal Good on the cable car and at Ngong Ping; patchy on Lantau's hill trails if you walk rather than ride.

  4. Day 4 Macau

    Macau: the historic centre

    TurboJET or Cotai Water Jet ferry from Hong Kong, about 1 hour, or the bus over the Hong Kong–Zhuhai–Macau Bridge, about 40 minutes.

    Take the ferry to Macau. Walk from Senado Square up to the Ruins of St Paul's and the Mount Fortress, then on to the A-Ma Temple at the southern tip. In the evening, visit the Taipa Village lanes and try a Portuguese egg tart.

    Signal Hong Kong signal fades mid-crossing; your phone switches to CTM in Macau. On the bridge bus, expect a short gap in the undersea tunnel.

  5. Day 5 Guangzhou

    Macau to Guangzhou via Zhuhai

    Gongbei border crossing on foot, then the intercity train from Zhuhai to Guangzhou South, about 1 hour.

    Walk across the Gongbei border into Zhuhai and take the intercity train to Guangzhou. In the afternoon, visit the Chen Clan Ancestral Hall, then walk Shamian Island's colonial streets. After dark, walk the Pearl River waterfront to see Canton Tower lit up.

  6. Day 6 Guangzhou

    Guangzhou: Yuexiu Park and dim sum

    Start with dim sum at a traditional teahouse, then walk Yuexiu Park to the Five Rams statue and the Zhenhai Tower museum. Visit the Mausoleum of the Nanyue King, then go to Beijing Road's pedestrian street with its glass panels over old road layers. Set up Alipay or WeChat Pay with a foreign card if you have not already.

    Signal Strong across the city and on the metro. Use Amap or Apple Maps, which are more accurate than Google Maps in the mainland.

  7. Day 7 Yangshuo

    High-speed train to Guilin and on to Yangshuo

    High-speed train from Guangzhou South, about 2.5 to 3 hours.

    Take a high-speed train west from Guangzhou South into Guangxi. Get off at Yangshuo station in Xingping for the Li River scenery, or continue to Guilin and take the express bus to Yangshuo. In the evening, walk West Street and up a riverside path to see the peaks at dusk.

    Signal Good on the high-speed line with brief drops in long tunnels through the hills; good 4G and 5G in Yangshuo town.

  8. Day 8 Yangshuo

    Li River and Xingping

    Take a bamboo raft or boat on the Li River between Yangshuo and Xingping, passing the karst peaks shown on the 20-yuan note. In Xingping, walk the old street and climb Laozhai Hill for the view over the river bend. Book river trips in advance in busy seasons.

    Signal Generally covered on the river, but signal weakens in the narrow stretches between the peaks and on Laozhai Hill's upper steps.

  9. Day 9 Yangshuo

    Cycling the Yulong River

    Hire a bike or e-bike and ride the lanes along the Yulong River past rice paddies and villages to the Dragon Bridge, an old stone arch. Take a bamboo raft back downstream if you like. In the late afternoon, climb Moon Hill for its natural arch and the view across the valley.

    Signal Coverage is good on the main roads but drops in the side valleys; download an offline map before cycling.

  10. Day 10 Hong Kong

    Back to Hong Kong via Shenzhen

    High-speed train from Guilin or Yangshuo, about 3 to 3.5 hours to Shenzhen or West Kowloon.

    Take the high-speed train back east. Some trains run direct to Hong Kong West Kowloon, with immigration for both sides in the station; otherwise change in Shenzhen and cross at Futian or Lo Wu. Spend the evening on the Tsim Sha Tsui promenade for the Symphony of Lights show.

    Signal Your phone switches back to a Hong Kong network after immigration. Apps blocked in the mainland work normally again on Hong Kong data and wifi.

Staying connected on this route

  1. Test WhatsApp, Google and your banking app as soon as you cross into Zhuhai, and keep a VPN installed in case a service blocks the roaming route.
  2. Set up Alipay or WeChat Pay with a foreign card before you reach the mainland; many small vendors there do not take cards or cash.
  3. Taiwan is not on this plan, so switch data off if you add a side trip to Taipei.
