How much data do you need for China? Budget the trip first

Before we follow that fortnight through, there’s one piece of preparation to do alongside the data choice. China restricts many foreign websites and services, including some banking and internet-calling services, as Smartraveller explains. A network name on an eSIM listing won’t tell you which apps you’ll be able to use, and we haven’t confirmed every app on every SIM Shop China offer.

If an app is essential to the trip, send us its name and the exact plan you’re considering before buying. Our China phone-preparation checklist takes you through saved addresses, payment arrangements and account access, including Australian-number login codes, while the China buying guide helps with the plan itself. If we can’t confirm access to a must-have service, choose a service whose provider can confirm it, and keep essential addresses and bookings available offline. A larger data allowance won’t fix that part of the preparation.

For our imagined trip, let’s set aside 400MB a day, plus 1GB spare for changes of plan. Over 14 days, that comes to 6.6GB. The 400MB is a chosen planning allowance, rather than a measured average for China or a promise about what particular apps will use.

That gives us something useful to compare with the plans: 5GB would leave this trip 1.6GB short, while the 10GB/30-day offer at A$24.95 covers the budget. We don’t need to jump straight to 20GB for this example, although a trip with regular video uploads or a laptop could need a different amount.

If you already have a reliable picture of your daily mobile use, you can work through the same calculation with that figure: multiply it by the days away, then add any extra downloads and the reserve you want. Music or video already included in the daily total doesn’t need to be added again. Otherwise, the planner gives you a starting estimate without asking you to build a spreadsheet before your holiday.

Here’s how the fortnight sits beside two other assumed trips, so you can see how changing the daily use and length changes the result:

The three-week example comes to 16.7GB, so 20GB would leave 3.3GB beyond that budget. If your own daily use is higher, change that figure before deciding which allowance to buy.

Back at the hotel, Wi-Fi can take care of the less exciting jobs: photo backups, app updates and downloading something for the next train journey. Keeping those off mobile data leaves more of the allowance for the day out, while choosing a lower video quality can help if you do want to stream along the way.

A laptop deserves its own place in the budget, because its uploads and updates add to what your phone uses. There’s a separate buying question here too: hotspot availability on these China plans depends on the phone and local network. If you need it for work, send us the exact offer, phone model and what the laptop needs to do before paying. If we can’t confirm that sharing requirement, use Wi-Fi you can test at your accommodation for essential work.

With the fortnight’s budget in mind, here are the selected China-only options. The price and running days sit alongside the time you have to start after buying, which matters if you’re the sort of person who likes to get the travel admin out of the way early.

For the 10GB offer we’ve been following, you need to start within 60 days of purchase, then its 30 days of service begin at the first network connection. Buying months ahead and leaving it untouched until the flight may therefore put the trip outside its start window. The 1GB offer allows 180 days to start, but that longer buying window doesn’t add data or turn it into a thirty-day plan.

If Hong Kong or Macao is part of the holiday, that also changes the choice: the China-only offers above don’t include those stops. Our regional-versus-separate-plan comparison helps you cover the whole route. Once you’ve settled the dates and stops, the China plan page has the selected offer’s price and details before you pay.

If the planner can’t find a suitable match, email hello@thesimshop.com.au with your dates, stops, estimated data and any laptop use. That gives us the details to check a fit before you pay.

Buy within the chosen plan’s start window and save the setup email with your first accommodation address and booking details. After landing, finish the airport Wi-Fi sign-in and open a normal webpage before installing from the email; if that connection won’t stay working, use hotel Wi-Fi or another steady, trusted connection.

With the allowance chosen and those first-day details saved, there’s a little less admin waiting at arrivals. The next job can be getting into the city and finding something to eat.
