Best eSIM for China, Hong Kong & Macau (2026)
Choose a regional eSIM for China, Hong Kong and Macau by trip length and data: 7-day, 10GB and 20GB picks, plus options for Taiwan.
Published 2026-11-07 Updated 2026-11-09
For a trip covering mainland China, Hong Kong and Macau, my default fixed-data choice is Nomad Greater China. I’d buy 10GB / 30 days for a week of moderate use, or 20GB / 30 days if I expect to use about 20GB anywhere across the trip. The same product also includes Taiwan. Yesim Asia Pacific is another confirmed one-eSIM option for all four destinations, and also includes Japan and South Korea.
Choose Saily Asia and Oceania instead if you need its wider coverage or want 25GB valid for 60 days. For heavy phone-only use without Taiwan, Holafly’s separate three-destination unlimited product is another option, with a 1GB-per-day hotspot limit.
Nomad and Saily regional information below comes from official brand pages checked on 7 November 2026; Ubigi examples and Yesim’s separate destination options were checked on 8 November 2026, and Yesim Asia Pacific’s six named destinations on 9 November 2026. My existing China reviews are field tests of specific mainland plans, not these regional products.

Quick picks for your exact itinerary
| Your trip and data needs | My pick | Why it fits |
|---|---|---|
| Mainland China + Hong Kong, 7 days, light use up to 5GB | Nomad Greater China 5GB / 30 days | Covers both stops; Macau and Taiwan are included if your plans change |
| Mainland + Hong Kong + Macau, 7 days, around 6GB | Nomad Greater China 10GB / 30 days | Enough for the moderate-use planning estimate below |
| Three destinations, 10 days, up to 10GB | Nomad Greater China 10GB / 30 days | One shared allowance for the whole itinerary |
| Three destinations, 15 days, around 12–20GB | Nomad Greater China 20GB / 30 days | Covers the full window and avoids a daily allowance |
| Any of the four destinations, 20–25GB over 31–60 days | Saily Asia and Oceania 25GB / 60 days | Its longer fixed-data option covers that window |
| Mainland China + Japan + South Korea only | Nomad China–Japan–South Korea | Dedicated three-country product; compare with Yesim Asia Pacific, which also covers Hong Kong, Macau and Taiwan |
| Mainland China + Hong Kong + Macau + Taiwan + Japan + South Korea | Yesim Asia Pacific | All six destinations are confirmed within its 15-destination coverage list; compare its price and validity with other regional plans |
| Adding Japan, South Korea or other included Asian stops | Saily Asia and Oceania, sized for the whole trip | Also compare Yesim Asia Pacific if every stop is among its 15 listed destinations |
| Mainland + Taiwan, or all four destinations | Nomad Greater China 10GB or 20GB / 30 days, according to use | Taiwan is explicitly included; see the Taiwan section |
These choices prioritize exact coverage, sufficient data and a useful validity period. Prices below retain the currencies shown by the official pages; I haven’t ranked different currencies as if they were the same amount.
The Nomad link below is for Greater China. Confirm all four destinations, the amount of data and the validity period before buying.

Which eSIMs cover China, Hong Kong, Macau and Taiwan?
A mainland China plan can have a Hong Kong internet exit without including Hong Kong as a place where you can use it. Check the product’s destination list, rather than its brand name or routing location.
| Exact product | Mainland China | Hong Kong | Macau | Taiwan | Main use |
|---|---|---|---|---|---|
| Nomad Greater China | Yes | Yes | Yes | Yes | Fixed data for these destinations |
| Yesim Asia Pacific | Yes | Yes | Yes | Yes | One regional eSIM for all four, plus Japan, South Korea and other included stops |
| Saily Asia and Oceania | Yes | Yes | Yes | Yes | These four plus other included Asian/Oceania stops |
| Ubigi Asia regional plan | Yes | Yes | Yes | Yes | 10 GB / 30 days listed at $42.00 USD; verify exact SKU coverage |
| Holafly Hong Kong, Macau and China | Yes | Yes | Yes | No | Unlimited phone data for the three-destination route |
| Nomad China–Japan–South Korea | Yes | No | No | No | A separate plan for mainland China, Japan and South Korea |
Macau may be written Macao in a provider’s list. “Greater China” and “Asia” aren’t standardized coverage promises: the explicit list for the selected product decides.
Yesim offers both choices: its Asia Pacific plan is one shared regional option covering all four, while its separate destination plans each cover only the named destination.
Traveling between mainland China, Japan and South Korea?
If your trip is mainland China + Japan + South Korea, compare Nomad China–Japan–South Korea with Yesim Asia Pacific. Nomad’s three-country product does not include Hong Kong, Macau or Taiwan; Yesim’s regional product includes all six destinations. Choose by total cost, data and validity, not just the number of destinations.
See Nomad China, Japan & South Korea eSIM ↗
My Shanghai speed and app checks were on Nomad’s mainland-only China plan, not the three-country regional plan. Confirm the regional package’s current data amounts, validity and destination list at checkout.
Best plans for 7, 10, 15 and 30 days
My data usage guide uses roughly 0.8GB per day for moderate use: maps, messages, social media and occasional calls. That’s a planning assumption, not a measured average for this regional route. Your video and hotspot use can change it substantially.
| Whole-trip length | Moderate-use estimate | The actual package I’d buy | Verified listed price |
|---|---|---|---|
| 7 days | About 6GB | Nomad Greater China 10GB / 30 days | €17.02 |
| 10 days | About 8GB | Nomad Greater China 10GB / 30 days | €17.02 |
| 15 days | About 12GB | Nomad Greater China 20GB / 30 days | €25.97 |
| 30 days | About 24GB | Saily Asia and Oceania 25GB / 60 days | $48.99 USD |
| 31–60 days, with a known 20–25GB budget | Size by total use, not days alone | Saily Asia and Oceania 25GB / 60 days | $48.99 USD |
For 30 days with frequent video or laptop use, I’d move up to Nomad Greater China 50GB / 30 days, provided the entire itinerary fits that validity window. If you use only 5GB in a month, a smaller 30-day bundle is enough. If you expect more than 50GB, budget for additional data rather than treating the largest fixed bundle as unlimited.
Count from your first covered stop. Three days in Hong Kong, seven in mainland China and one in Macau create an 11-day window. A 7-day pass doesn’t cover that itinerary simply because the mainland leg lasts a week. The fixed 30-day packages above give you room for all three stops.
Need 5GB, 10GB or 20GB?
If you already know your data budget, use it instead of a daily estimate.
| Your requirement | My fixed-data choice | When I’d change it |
|---|---|---|
| Up to 5GB within 30 days | Nomad Greater China 5GB / 30 days | Move to 10GB if you expect a week of moderate use |
| Up to 10GB within 30 days | Nomad Greater China 10GB / 30 days | Move to 20GB for more video or a two-week moderate-use trip |
| 20GB within 30 days | Nomad Greater China 20GB / 30 days | Choose Saily 25GB / 60 days if you need longer validity or its wider coverage |
| 20GB across 31–60 days | Saily Asia and Oceania 25GB / 60 days | If you need more than 25GB, budget for another suitable package |
| 21–50GB within 30 days | Nomad Greater China 50GB / 30 days | Consider a day-based unlimited option for heavy phone use, checking hotspot and fair-use rules |
My 20GB recommendation is the same for a 7-day, 15-day or 30-day trip: Nomad Greater China 20GB / 30 days, as long as all your stops are included and the full window fits. You buy one 20GB allowance shared across the destinations, not 20GB per destination.
Saily’s corresponding fixed package is 25GB / 60 days, not a regional 20GB plan. Don’t substitute the price of its mainland-only 20GB product.
The regional plans I’d consider
Nomad Greater China: my default for a fixed allowance
The four-destination list and a range of fixed bundles make this the clearest fit for a mainland/Hong Kong/Macau itinerary, including one that adds Taiwan.
| Shared data | Validity | Listed price, EUR |
|---|---|---|
| 1GB | 7 days | €4.48 |
| 3GB | 30 days | €8.96 |
| 5GB | 30 days | €13.43 |
| 10GB | 30 days | €17.02 |
| 20GB | 30 days | €25.97 |
| 50GB | 30 days | €40.30 |
These are the regional packages and the EUR prices displayed when checked. The Greater China 50GB package shown here lasts 30 days; it isn’t the 45-day China-only package in my mainland review. A different storefront currency may show different amounts.
I’d buy: 5GB for a light week, 10GB for a moderate week or ten days, and 20GB for roughly two weeks or a known 20GB budget. The 1GB / 7-day option is only for very light use with substantial Wi-Fi access.
Nomad says this product supports hotspot sharing; tethered data uses the same allowance. In my mainland China-plan tests, hotspot connected but was slow. I haven’t measured hotspot performance on Greater China, so I wouldn’t treat the allowance alone as proof it’s suitable for a work laptop. Read my Nomad tests.

Saily Asia and Oceania: for more stops or a longer window
The current product lists 22 destinations, including mainland China, Hong Kong, Macau, Taiwan, Japan, South Korea, Australia and New Zealand. It suits a trip that goes beyond the four-destination area; check every extra stop on the actual package.
| Shared data | Validity | Listed price, USD |
|---|---|---|
| 1GB | 7 days | $4.99 |
| 3GB | 30 days | $12.49 |
| 5GB | 30 days | $19.49 |
| 10GB | 30 days | $35.99 |
| 25GB | 60 days | $48.99 |
I’d buy the 25GB / 60-day package if I needed 20–25GB over 31–60 days, or about 24GB over a month and wanted the longer validity. For shorter trips with less use, the smaller packages are valid options.
Saily advertises hotspot sharing without a separate sharing cap; a fixed package still has its stated total GB. Its listed credits are future account credit, not an immediate reduction to the prices above. I haven’t applied the China review’s discount to these regional prices or tested this regional package. Read my Saily review.
The button opens my Saily affiliate link. Choose Asia and Oceania, rather than China, and check the GB/days before paying.
Open Saily — select Asia and Oceania ↗
Yesim Asia Pacific: six relevant destinations on one eSIM
Yesim Asia Pacific lists 15 destinations, including mainland China, Hong Kong, Macau, Taiwan, Japan and South Korea. Unlike its China-only or individual Hong Kong, Macau and Taiwan plans, this is a single regional product for multi-stop trips. Yesim lists fixed-data and unlimited options; compare the exact package’s data, price, validity and hotspot conditions before purchasing. I have tested Yesim’s mainland China plan, not Asia Pacific across these destinations.
See Yesim Asia Pacific regional plans ↗
Ubigi: a regional plan or separate China, Hong Kong, Macau and Taiwan plans
Ubigi Asia is another option for a multi-stop itinerary. The 10 GB / 30 days regional example is $42.00 USD before any first-order discount. It is not the same product as Ubigi China 10 GB / 30 days ($17.00). Check whether your selected regional SKU covers every stop, rather than assuming every plan labeled Asia is identical.
For one-stop travelers, Ubigi separately lists 10 GB / 30 days at $14.00 for Hong Kong, $16.00 for Macau, and $14.00 for Taiwan. Those local prices do not buy four-country access.
Ubigi supplied the code ROAMTESTED for 10% off a new customer’s first one-off or annual plan in any destination, not monthly plans or top-ups; it has not been independently checked out here. My Ubigi China review separates pricing from pending field tests.

Holafly’s three-destination unlimited option
If you expect to use much more than 20GB on your phone during a short trip, consider Holafly Hong Kong, Macau and China, selecting the full number of days from your first stop to your last. Its published rules allow 1GB per day of hotspot sharing, and partner-network fair-use restrictions can still reduce speeds.
I wouldn’t choose this specific product for a trip that includes Taiwan, or for heavy laptop tethering. It covers only the three destinations in its name. A large fixed bundle gives you a clearer total allowance for sharing. I haven’t field-tested this regional product.
One regional eSIM or separate country plans?
A regional package is convenient when you want one installed profile and one shared data balance. Separate local plans can still be worthwhile when most of your data use is concentrated in one place or you already have a usable plan.
Compare the whole basket:
- Regional cost: one package with enough shared data and enough time for the entire route.
- Separate-plan cost: mainland package + Hong Kong package + Macau package + Taiwan package, including only the stops you need.
- For each local package, check that its own data allowance covers use in that destination.
For example, suppose you need 8GB on the mainland, 1GB in Hong Kong and 1GB in Macau. A shared 10GB regional bundle meets that stated budget. Three separate 3GB bundles give 9GB in total but leave you short on the mainland, even if their combined price looks attractive.
Use the same checkout currency, current prices and discount eligibility for both baskets. I haven’t verified a like-for-like set of current local-package prices here, so I wouldn’t claim the regional package always saves money.
An existing mainland eSIM doesn’t gain Hong Kong or Macau coverage when you cross a border. If you keep it, budget for a suitable additional product for the other stops.
Yesim: separate destination plans (or one Asia Pacific eSIM)
Yesim offers fixed-data and unlimited options for each of these destinations. Its local plans are data-only, and each covers its own destination: buying the mainland China package doesn’t include Hong Kong, Macau or Taiwan.
| Destination | Fixed data (30 days) | Plans |
|---|---|---|
| Mainland China | 1, 3, 5, 10, 20 or 30 GB | View plans |
| Hong Kong | 1, 5, 10, 20 or 30 GB | View plans |
| Macau | 1, 3, 5 or 10 GB | View plans |
| Taiwan | 1, 3, 5, 10, 20 or 30 GB | View plans |
I’d consider these if I already had a mainland plan and needed data for an extra stop. A 1GB / 30-day Hong Kong, Macau or Taiwan bundle can suit light maps and messaging; choose a larger allowance if you expect video or heavier use. The allowances are separate, so size each one for that destination and compare the complete basket with a shared regional plan.
If you prefer one package instead of separate local allowances, Yesim Asia Pacific already includes mainland China, Hong Kong, Macau and Taiwan, plus Japan and South Korea. Compare the regional price and allowance with your complete basket of local plans. My Yesim China review reports field tests of its mainland plan only.
Also visiting Taiwan? Two-stop and four-stop choices
Mainland China + Taiwan only
You don’t have to visit Hong Kong or Macau to use a four-destination package. Nomad Greater China still fits the two-stop route because both destinations are listed.
If you already have Yesim for the mainland, compare adding a separate Yesim Taiwan plan with buying a regional package. Its data allowance is for Taiwan, not shared with your China plan.
| Your total data and trip window | My pick |
|---|---|
| Up to 5GB within 30 days | Nomad Greater China 5GB / 30 days |
| Up to 10GB within 30 days | Nomad Greater China 10GB / 30 days |
| Up to 20GB within 30 days | Nomad Greater China 20GB / 30 days |
| 20–25GB over 31–60 days | Saily Asia and Oceania 25GB / 60 days |
The extra covered destinations don’t mean you must activate or use the plan in each of them.
Mainland China + Hong Kong + Macau + Taiwan
Keep the same Nomad Greater China recommendation if the allowance and 30-day validity cover your whole trip. Choose Saily’s 25GB / 60-day regional option if you need the longer window or its additional destinations.
Adding Taiwan does change the Holafly three-destination choice: that specific product doesn’t include it. Nomad’s China–Japan–South Korea product also doesn’t include Taiwan, Hong Kong or Macau.
Don’t buy by the regional name alone. Verify the four places, the exact data amount and the start rule on the product you are about to pay for.

WhatsApp, Google Maps and ChatGPT in mainland China
Coverage answers whether the package can connect to a local mobile network. Internet routing affects which services you can reach from that connection. Those are separate checks.
In my mainland tests, WhatsApp, Google Maps, Instagram and ChatGPT worked on Nomad, while TikTok and Microsoft Copilot didn’t. Yesim’s tested mainland plan also opened WhatsApp, Google Maps and ChatGPT, as well as TikTok, and its hotspot worked well. The Google checks included Google Maps; these are app-access results, not an assessment of map accuracy on every route. The details and screenshots are in my Nomad and Yesim reviews.
Nomad’s current China help explicitly lists Google Maps and WhatsApp as working through its international data routing. Saily’s official Google guide discusses Maps access, but its China FAQ and WhatsApp guide conflict about whether WhatsApp requires a VPN; I haven’t found an explicit Saily China ChatGPT support promise. Those are brand statements for the described services, not my tests of the regional packages above.
I haven’t verified a complete app-access matrix for Nomad Greater China, Saily Asia and Oceania or Holafly’s three-destination product. The mainland plan results don’t automatically prove the same outcome on a different regional SKU. For a China eSIM specifically for WhatsApp, Google Maps or ChatGPT, distinguish the destination list from the app evidence in my China eSIM comparison.
If a particular app is essential, get confirmation for the named regional package, and keep a backup option. Hotel Wi-Fi uses its own connection; an eSIM’s routing doesn’t change it. My China VPN comparison covers a separate backup approach.
Activation, validity and border crossings
| Product | Published activation window | What starts the plan | What to remember |
|---|---|---|---|
| Nomad Greater China | Within 60 days of purchase | Normally connection to a supported destination network; follow any manual step in the installation email | The page says validity starts automatically after the activation deadline |
| Saily Asia and Oceania | Within 180 days of purchase | First covered destination with the line and roaming enabled; automatically after 180 days if unused | A Hong Kong connection can start it before the mainland leg |
| Holafly three-destination product | Check the selected order’s terms | Connection to a supported network with the eSIM enabled at the destination | Buy enough continuous days for all three stops |
Buy and install Nomad before entering mainland China. Its China help page says new plans cannot be purchased there. It allows add-on purchases from the mainland while the original plan remains active; arrange that before expiry and before the data balance reaches zero.
Install while you have a reliable internet connection and follow the instructions for the specific order. Installing a profile, starting its data validity and retaining refund eligibility can have different rules.
Crossing from Hong Kong into mainland China doesn’t create a fresh allowance or restart the validity period. Keep the regional eSIM selected for mobile data and use its required roaming settings. A network change may require reconnection; I haven’t timed those border crossings.
On Nomad, a suitable add-on can start after the original package ends, with unused data not rolling over; availability depends on the eSIM. Saily offers top-ups, with a new package starting after the current data is used up. Check availability before you rely on either to extend a trip, and don’t assume an add-on is a free extension.
How I compared these plans
I used current official product and help pages for coverage, package sizes, validity, listed prices and sharing conditions. Nomad prices are EUR; Saily prices are USD. I haven’t converted one into the other, applied unverified regional discount codes or treated account credits as checkout savings.
The recommendations above compare the confirmed fixed-data options by route and required allowance. They aren’t a lowest-price ranking of every seller or every unlimited variant. Brand review links identify where I have field-test evidence and where the content is based on published terms.
FAQ
Does a China eSIM work in Hong Kong and Macau?
Only if those destinations appear in that exact package’s coverage list. A mainland-only plan doesn’t acquire coverage at the border. Nomad Greater China and Saily Asia and Oceania explicitly include all three.
Does Greater China include Taiwan?
Nomad’s current Greater China product includes mainland China, Hong Kong, Macau and Taiwan. Other sellers can use regional labels differently, so check their product list rather than assuming the same meaning.
Is one allowance shared across all four destinations?
For the fixed regional packages compared here, yes. A 20GB Greater China bundle is 20GB for the trip, not a separate 20GB in each place. Hotspot use also consumes the same allowance.
Which plan would you buy for 7 days?
Nomad Greater China 10GB / 30 days for moderate use, or 5GB / 30 days for light use up to 5GB. If you already know you’ll need 20GB, choose its 20GB / 30-day bundle instead.
Does my phone need to be unlocked?
Yes: it needs eSIM support and must accept other carriers’ SIMs. Carrier unlocking is separate from your screen passcode. See the checks in my iPhone guide or Google Pixel guide.
Do these plans include a mainland Chinese phone number?
The fixed Nomad and Saily packages compared here are data packages. Don’t buy them expecting a bundled mainland +86 number for ordinary calls or SMS. Check any separately sold calling feature for its own number and service terms.
My final choice
For mainland China, Hong Kong and Macau, I’d start with Nomad Greater China: 10GB / 30 days for a moderate week, or 20GB / 30 days for a known 20GB budget. Add Taiwan without changing that product, provided the whole trip stays within its validity.
I’d switch to Saily Asia and Oceania 25GB / 60 days for a 20–25GB budget spread over a longer trip or a route that needs its wider coverage. The GB amount, included stops and continuous validity matter more than matching the plan’s name to the number of days you travel.
