China eSIMs for Australians: choose the exact plan, not just the gigabytes

When you’re choosing mobile data for China, the amount of data is only part of the purchase. The date you buy, where the service must first be activated and what happens when the allowance runs out can change which plan suits the trip, even when two offers both say “20GB for 30 days”.

For example, some of our plans must start within 60 days of purchase. The CUniq offers below need advance activation outside China. Buying either one months ahead without checking its timing could leave you with the wrong service before you’ve even packed.

This comparison includes the SIM Shop plans we sell and CUniq’s Australian offers. The selected prices and terms were checked on 25 October 2026. We haven’t tested their speeds, internet routing or app access in China.

A network name tells you which mobile network is listed for the service. It doesn’t establish where the internet traffic exits, whether a particular overseas website will load or whether a payment app accepts your account and card.

If you need a particular overseas app, ask about it separately before buying. None of the plan details checked for this comparison establishes guaranteed access to a named app. A listed mobile network alone can’t answer that question.

Our checked China plans are data-only, without an ordinary Chinese number, calls or SMS. They don’t receive a carrier text sent to your Australian number, and having a data connection doesn’t guarantee a payment application’s registration or approval. The China phone-preparation guide covers those account, address and payment tasks separately.

Our China eSIM range has these fixed allowances, all priced in Australian dollars:

The days of service start at the first supported network connection. The last column is the time you have to begin after buying, rather than extra days added to a plan that’s already running.

The 3GB through 50GB 30-day variants are non-reloadable: data stops when the allowance is exhausted. Their speed is described as network dependent. The 20GB offer names China Telecom; the other checked 30-day offers name CMCC, or China Mobile.

The 1GB/seven-day and 50GB/180-day variants list China Mobile 3G/4G/5G and allow same-area data reload within active validity. Both 50GB options provide one total allowance, not a daily or monthly refill. The 180-day option gives you longer to use the same amount of data.

For 10GB of phone data within a month, the A$24.95 offer meets the amount and duration. Hotspot is a separate question: the current terms across these offers say it may depend on your phone and the local network. If a laptop connection is essential, confirm the exact plan’s suitability before buying. Spending more on the 180-day plan doesn’t establish a hotspot guarantee.

Suppose you’re 90 days from departure and want our 10GB/30-day offer. Its 60-day start window doesn’t fit buying now and waiting until that trip. Arrange the purchase within the matching window, rather than installing before departure to try to rescue the timing.

Our 1GB/seven-day plan has a longer start window, but that doesn’t make 1GB suitable for a trip needing 10GB. Similarly, the longer 50GB option may be unnecessary for your holiday. Match the data and duration first, then buy at the appropriate time.

The non-reloadable term matters after purchase too. If you use all 10GB and need another 10GB, the quoted option is a new 10GB/30-day purchase at A$24.95, rather than a top-up to the original profile. Install that new profile on dependable Wi-Fi under its own issued instructions. Keep a working profile installed rather than deleting it as an experiment.

CUniq Australia’s selected China and Macau 20GB/30-day offer displays A$16, compared with A$34.95 for our China 20GB/30-day offer. That is a displayed difference of A$18.95, so price is a valid reason to investigate it.

CUniq’s page has a conflicting suggested-retail-price line, so this comparison uses the displayed A$16 selling price. The selected format is eSIM-only, despite generic physical SIM text further down, and it is non-rechargeable.

CUniq’s named products require advance activation outside China, and its permitted-region list explicitly includes Australia. An Australian traveller can therefore follow that advance-activation route before departure, within the thirty-day timing explained below, without routing the flight through Hong Kong. First attempting activation after arrival in Shanghai doesn’t meet the published requirement.

Keep CUniq’s advance-activation instructions with that purchase; our selected plans follow the different after-landing route described below.

CUniq’s 4GB/two-day offer displays A$4. Its terms specify expiry at 23:59 Hong Kong time on the second day, rather than promising 48 elapsed hours from first use.

For example, if destination data begins at 23:30 Hong Kong time on the first day, the stated end of the second day is about 24 hours and 29 minutes later. That’s the calendar rule applied to a late-night arrival, rather than a measured activation. Check the final hour if you need data for a flight home on day two.

Both checked CUniq products separate advance activation from first destination data use. They say advance activation alone doesn’t begin the data countdown, but an unused package automatically starts its validity after 30 days following activation.

Activate within thirty days before destination use to avoid that automatic early start. For example, activation seven days before arrival leaves first destination data use to begin the running period. Activation 45 days beforehand instead puts arrival roughly fifteen days into the running period: the two-day package is already over, and the 30-day package is no longer fresh. The separately stated one-year purchase life doesn’t pause that rule.

The checked CUniq offers name China and Macau as data destinations. Permission to activate in Hong Kong isn’t proof that Hong Kong data is included, and our China-only plans don’t establish coverage for either side trip.

For a China-and-Macau itinerary, CUniq’s quoted country list includes both places. For Hong Kong, neither its quoted China/Macau offer nor our quoted China-only offers supplies that additional destination allowance, so a separate Hong Kong or an explicitly inclusive regional service is needed.

CUniq also publishes a separate installation condition for China-released eSIM handsets. That is a provider and device-origin rule, not evidence that an Australian traveller’s phone follows it merely because the holiday is in China. Compatibility needs the exact model and purchase region where relevant.

CUniq’s A$16 option is worth considering for 20GB in China and Macau if you can complete advance activation in Australia within the stated window. Our 20GB/30-day China-only offer costs A$34.95 and follows our install-after-landing route. Both use Australian-dollar prices; the allowance, destinations and activation arrangements are the useful differences.

Within our range, choose a smaller allowance if it covers your trip. The longer 50GB option makes sense when you need its longer validity, rather than as a way to obtain unconfirmed app access or hotspot performance.

For our plans, check compatibility and unlock status, buy within the selected start window and save the order email before departure. Follow that email to install after landing on airport Wi-Fi. If it isn’t working, use hotel Wi-Fi or another steady trusted Wi-Fi connection. Keep the first address and booking references offline as well, alongside whichever account-recovery options your essential services support.
