UPeSIM offers fixed-data China eSIMs on China Unicom, with 7-, 10- and 30-day options. Its official information names WhatsApp and Google Maps, but direct ChatGPT access is not assured. Here is how to match data and validity to your trip, and check the RoamTested discount before buying.
Testing status: This review uses official product information and a discount-cart screenshot. RoamTested’s China speed, app-access and hotspot tests are pending.

Plans and pricing
UPeSIM’s China plans are prepaid fixed-data packages. Current product cards list 1 GB / 7 days from €1.99, through 20 GB / 30 days at €35.99. The prices below are in euros, including VAT; confirm the selected package and final total before paying.
For a seven-day trip, 1 GB suits only very light use; choose 5 GB / 10 days if that better matches your total needs. For fifteen days, the 5 GB package expires too soon: compare the thirty-day packages instead. Need 20 GB? Choose 20 GB / 30 days, provided your trip fits that window.
Which Upesim plan fits your trip?
Choose your trip length and typical data use. We compare plans by total price.
Estimated data need: 16.8GB(including 20% buffer)
Covers your trip length and estimated data needs.
Data needs are estimated from your selected usage level plus a 20% buffer. Confirm prices and fair-use restrictions at checkout.
The calculator uses planning assumptions, not measured visitor averages. If it suggests multiple packages, check how each will be installed or topped up and when it expires; their validity does not automatically add together.

UPeSIM China plans and prices
Fixed-data plans
| Data | Validity | Price |
|---|---|---|
| 1GB | 7days | €1.99 |
| 5GB | 10days | €11.99 |
| 10GB | 30days | €23.99 |
| 20GB | 30days | €35.99 |
Before buying: Match validity as carefully as GB. Unused data expires, and the China packages reviewed here do not supply a phone number, carrier voice calls or SMS. WhatsApp calls use data and are a separate capability.
Visiting Hong Kong, Macau, Taiwan, Japan or South Korea too?
The China-only plan covers mainland China. UPeSIM’s separate Asia eSIM lists 16 destinations, including mainland China, Hong Kong, Macau, Taiwan, Japan and South Korea. Compare that regional product if your trip crosses borders; buying separate country packages does not create one shared regional allowance.
Single-destination options include Hong Kong, Macau, Taiwan, Japan and South Korea. For other regional choices, see the China, Hong Kong and Macau comparison.

Official information and testing status
UPeSIM lists China Unicom with 4G/LTE and 5G where available. Its China page explicitly names WhatsApp and Google Maps as accessible without setting up a separate VPN app. These are official claims, not RoamTested results.
ChatGPT needs a separate caveat: UPeSIM’s FAQ acknowledges China access problems with ChatGPT and Gemini and suggests an alternative service. Do not buy this plan assuming direct access to either is guaranteed.
UPeSIM officially permits hotspot sharing; connected devices use your purchased allowance. China-plan app claims do not establish how the Asia product performs.
Buying and activation
- Check that your phone supports travel eSIMs and is carrier-unlocked. Model-specific checks are in the iPhone and Google Pixel guides.
- Open UPeSIM’s China packages, choose data and validity, then check the code and total.
- Install with a reliable connection before departure. UPeSIM supplies a QR code and also advertises direct-click installation on supported devices.
- In China, select UPeSIM for mobile data and enable data roaming on that line. Validity starts with the first supported destination-network connection, rather than installation at home. Disable roaming on your home line to avoid home-carrier charges.
Keep the profile installed: UPeSIM says one eSIM can be installed on one device, once; deleting it prevents reinstallation. Eligible plans can be topped up through the app or website. Check your selected plan’s eligibility rather than assuming every purchase supports recharge or transfer.
Refunds: UPeSIM’s October 2026 terms ordinarily exclude cash refunds for delivered change-of-mind orders, even if unused; a never-installed eSIM may qualify for a discretionary twelve-month voucher. Locked or incompatible devices and customer-deleted profiles are excluded reasons. Report problems promptly, ideally within 24 hours. This recommendation does not remove conformity rights: unresolved service that fails to match the contract may qualify for a price reduction or refund.
Who should buy it
Consider it if you:
- Want fixed data with a known expiry rather than an Unlimited offer.
- Want to compare a China-only package with one regional allowance for the six destinations above.
- Want to install before departure and start validity when you connect at the destination.
UPeSIM alternatives for China
| If you… | Consider | Why |
|---|---|---|
| Want an Unlimited option | Yesim | Its China range includes Unlimited passes; partner-network fair-use restrictions still apply. |
| Want a China plan with RoamTested’s recorded ChatGPT checks | Nomad | ChatGPT worked in the tested China plan’s app checks. This does not guarantee every account or feature. |
| Need a separate number for calls or texts | Saily | Its optional paid US-number service is separate from data. It does not supply a Chinese +86 number or guarantee verification codes. |

What's not

- The China packages reviewed are fixed-data bundles, not Unlimited plans
- One device and one installation: a deleted eSIM cannot be reinstalled
Frequently asked questions
Does UPeSIM work in mainland China?
UPeSIM sells China eSIM plans using China Unicom, with 4G/LTE and 5G where available. These are official product details; RoamTested's independent China speed and reliability tests are pending.
Does UPeSIM China work with WhatsApp and Google Maps?
UPeSIM explicitly says WhatsApp and Google Maps are accessible with its China product through international roaming. RoamTested has not yet verified their performance or individual features in China. This claim should not automatically be applied to a separate regional product.
Does UPeSIM work with ChatGPT in China?
Do not assume direct access. UPeSIM's FAQ acknowledges ChatGPT and Gemini connection problems in China and suggests Poe as an alternative. That does not establish direct ChatGPT access, and RoamTested's field testing is pending.
What is the UPeSIM RoamTested promo code?
Enter RoamTested when checking a UPeSIM China plan. The cart screenshot above shows a reduction consistent with 10% after rounding. It verifies coupon application in that cart, not payment completion or eligibility for every plan and customer; confirm the final discount before buying.
Can I use a hotspot with UPeSIM?
Yes. UPeSIM's FAQ permits hotspot sharing on compatible devices. Connected devices use the purchased allowance. This is official permission, not a RoamTested measurement of China hotspot speed.
When does my UPeSIM plan start, and can I reinstall it?
Installing before departure does not start validity; the first connection to a supported destination network does. UPeSIM allows one device and one installation. Do not delete the eSIM to troubleshoot, because it cannot be reinstalled after deletion.
Can I top up my UPeSIM China eSIM?
UPeSIM offers top-ups through its website and app, subject to the selected eSIM's eligibility. Check the available top-up and remaining validity for your specific eSIM; do not assume a separate package purchase automatically extends the original plan.
Does UPeSIM China include Hong Kong, Macau, Taiwan, Japan or South Korea?
The China-only product is for mainland China. UPeSIM's Asia regional eSIM lists mainland China, Hong Kong, Macau, Taiwan, Japan and South Korea among its 16 destinations. Separate country eSIMs cover their named destination; check the selected product before buying.
Does UPeSIM provide a Chinese phone number or SMS?
No. These travel eSIMs are data-only: no assigned Chinese +86 number, carrier voice service or SMS. Internet messaging and calls can use your data if the app is accessible; that is different from carrier calling and SMS verification.
Can I get a refund on a UPeSIM China eSIM?
UPeSIM's terms ordinarily exclude cash refunds for delivered change-of-mind orders; a never-installed eSIM may qualify for a voucher valid for 12 months. Device incompatibility, carrier locks and deletion are excluded reasons. Contact support promptly, ideally within 24 hours, for a service problem. Statutory conformity rights remain, and an unresolved nonconforming service can qualify for a price reduction or refund.
