Before buying: TooSim publishes no priced Unlimited package for China, and fixed-data plans cannot be topped up. For longer trips, the calculator may estimate separate purchases; these are not automatic top-ups and each eSIM must be installed and activated separately. Confirm live prices before buying.
TooSim Asia eSIM for multi-country travel
TooSim also sells an Asia regional eSIM, from $7.99 for 1 GB / 7 days to $61.99 for 20 GB / 30 days. The regional plan covers mainland China, Hong Kong, Macau, Taiwan, Japan and South Korea, along with other Asian destinations.
Buying and activation
- Open TooSim’s website or the TooSim app, search for China and pick a plan. There’s no ID check.
- At checkout, enter
ROATSM10(10% off for new customers), then pay. TooSim sends the eSIM straight away: a QR code by email, or install instructions in the app. - Before you fly, install the eSIM at home, on Wi-Fi — you need an internet connection to install it. Installing doesn’t start the plan: TooSim says its days start only when you first use the eSIM at your destination.
- When you land in China, turn on the TooSim line, set it as your mobile data line and turn on data roaming.
Refunds: TooSim’s terms say you may get a refund if you haven’t scanned the QR code or used the data, so install the eSIM only once your trip is certain. If the eSIM doesn’t work and TooSim’s support can’t fix it, TooSim promises a full refund; you reach support by email or WhatsApp.
Who should buy it
Buy it if you:
- Want quick setup without an ID check — TooSim’s China eSIM arrives by email QR code, with in-app installation instructions as another option.
- Need to share data with a laptop or travel partner — TooSim allows free hotspot sharing within your purchased data allowance.
- Prefer a fixed-data pass with a month of validity — 3 GB / 30 days costs $25.99 or 10 GB / 30 days costs $69.99, before discounts. Validity begins on first use.
TooSim alternatives for China
For a different price structure, an Unlimited option or additional data, consider these alternatives:
| If you… | Pick | Why |
|---|---|---|
| Want unlimited data with the price upfront | Yesim | TooSim offers unlimited data only “by request”, with no published price. Yesim’s day passes work out to $2.52 a day on the 30-day pass (see my review). |
| Might run out of data mid-trip | Nomad | TooSim can’t top up a plan, so you’d need a new eSIM. Nomad sells add-on data while your plan is still running (see my review). |
| Are on a short trip with light use | Trip.com | Its China eSIM starts at $0.10 a day for 500 MB (see my review). |
If price is why you’re looking, here’s the cheapest of TooSim, Nomad and Yesim for the same data at current prices, with each brand’s code where it has one:
What's good
- 3 GB for 30 days is a $25.99 prepaid China option with a month-long validity period for light data use
- Free hotspot sharing lets you use the purchased data on a laptop or another device
- No ID verification and instant eSIM delivery by email QR code or instructions in the TooSim app
- Plan validity begins on first use at your destination, not when you buy the eSIM
- TooSim offers a full refund if the eSIM does not work and its support team cannot fix the problem
What's not
- China plans cost more than several alternatives: $13.99 for 1 GB and $117.99 for 20 GB
- No top-ups: when a plan's data runs out, you have to buy and install a new eSIM, while Nomad and Yesim let you top up the eSIM you already have
- No unlimited plan to buy — TooSim offers unlimited data only "by request", with no price or fair-use policy published, while Yesim's unlimited day passes run from 1 to 30 days
- TooSim's China page does not identify the network operator or explicitly guarantee Google Maps and ChatGPT access without a separate VPN
- Refunds end once you scan the QR code, unless the eSIM doesn't work and support can't fix it
Frequently asked questions
Does TooSim work in China?
Yes. TooSim's China eSIM provides prepaid mobile data for mainland China. The official page lists six fixed-data packages starting at $13.99 for 1 GB, with advertised 3G, 4G, LTE and 5G connectivity.
How much does TooSim cost in China?
From $13.99 for 1 GB over 7 days to $117.99 for 20 GB over 30 days — six plans in all, each with a fixed amount of data. Bigger plans cost less per GB, about $5.90 on the 20 GB plan, but that's still roughly three times what Yesim charges for the same data. Check today's prices on TooSim's website.
Does TooSim have unlimited data for China?
Not as a plan you can buy. TooSim's China page says unlimited data is available "by request", but it publishes no price or fair-use policy for it, so you'd have to ask its support. If you want unlimited data with the price upfront, Yesim's unlimited day passes run from 1 to 30 days.
Does TooSim's hotspot work in China?
Yes. TooSim says its China plans allow free hotspot sharing. You can share your mobile data with a laptop or other device, and that traffic uses the plan's purchased data allowance.
What happens when my TooSim data runs out?
Buy and install a new TooSim eSIM. China plans contain a fixed data allowance and do not support top-ups, so another eSIM and an internet connection for its installation will be needed.
Is TooSim cheaper than Airalo or Holafly in China?
Only if you use little data. Airalo and Holafly now sell only unlimited plans for China, so for a week or two of light use, TooSim's 3 GB or 5 GB plan costs a little less than theirs. For heavier use, their unlimited plans are better value — and Nomad and Yesim sell the same fixed data as TooSim for less than half its price.
Is there a TooSim promo code?
Yes. My code ROATSM10 takes 10% off for new customers: enter it at checkout on TooSim's website.
Can I get a refund on a TooSim eSIM?
TooSim's terms say you may get a refund if you haven't scanned the QR code or used the data, so install the eSIM only once your trip is certain. And if the eSIM doesn't work and TooSim's support can't fix it, TooSim promises a full refund. You reach support by email or WhatsApp.
Does TooSim give you a Chinese phone number?
No. TooSim's China plans are data only: there's no number, so you can't make calls or send texts with it. TooSim suggests apps like WhatsApp and FaceTime for calls and messages instead.
Does TooSim's China plan work in Hong Kong?
The standalone China eSIM covers mainland China only. For a trip that also includes Hong Kong, Macau, Taiwan, Japan or South Korea, choose TooSim's Asia regional eSIM, which covers all six destinations.
Does TooSim work with WhatsApp, Google Maps and ChatGPT in China?
TooSim explicitly lists WhatsApp for internet calls and messages on its China eSIM. Google Maps and ChatGPT also use mobile data, but TooSim does not specifically guarantee access to those services without a separate VPN in mainland China. Check access requirements if you need them.
