Cheap eSIM for China: how much should you spend?
Updated on
In short
Zas's cheapest eSIM for China costs €5.90 and includes 3 GB for 30 days. It is a sensible buy for maps, messages and bookings with frequent Wi-Fi. If you will use social media every day, I recommend 10 GB at €13.99 so the data lasts until the return journey.
Three gigabytes may cover light searches with hotel Wi-Fi and downloaded maps. Daily camera translation, calls and video posting move the traveller into another usage category.
Cheap Chinese data has little value if the route needs an unavailable app
The entry bundle can cover available navigation, translation, messaging and bookings at a low price, but saving starts with the digital ecosystem. An inexpensive gigabyte is useless when the entire route depends on a blocked service.
Download Chinese addresses, tickets and compatible maps first. Fifteen days of trains, camera translation and calls may justify the middle bundle by utility. Video and cloud backup can quickly exhaust an otherwise adequate option.

| Plan | Price | Approx. price/GB | Profile |
|---|---|---|---|
| 3 GB · 30 days | €5.90 | €1.97 | Light use with frequent Wi-Fi |
| 10 GB · 30 days | €13.99 | €1.40 | Daily use and social media |
| 20 GB · 30 days | €27.99 | €1.40 | Work, video or connection sharing |
The €5.90 plan is cheapest only if it lasts. When choosing between 3 and 10 GB, the €13.99 option is usually calmer for a trip with daily social media. In China, prepare the apps, tickets and Chinese addresses you will need before flying.
Before flying: prepare these details
- Download maps, tickets and entertainment before departure.
- Pause cloud backups and automatic app updates on mobile data.
- Reserve part of the allowance for the return transfer and last booking changes.
- Test required applications before relying on them after landing.
Save tickets, addresses in Chinese and offline translation. Having mobile data does not ensure that every app you normally use will be available in China. That leaves the smaller bundle for messages, changes and the journey home.
How can the small bundle last fifteen days in China?
Use Wi-Fi for media, download maps and translation, pause backups and reserve data for stations and new addresses.
Does the low price ensure my usual apps work?
No. Price, allowance and service access are different variables. Build a route that does not depend on one platform.
Can 3 GB last for 15 days?
Yes, with downloaded maps, messaging and Wi-Fi for video and photo uploads. Choose 10 GB if you post every day.
Is the price a monthly subscription?
No. You buy a prepaid allowance with a maximum validity; it does not renew because some days remain.
Is a local SIM always cheaper?
Not necessarily. Compare the final price, allowance, validity and any registration required at purchase.
