Who this site is for
The advisor is built for international visitors planning a short or medium-length trip to China who want mobile data without comparing dozens of nearly identical packages. It is not a mobile operator, reseller, payment processor, or customer-support desk.
How recommendations work
Device readiness comes first. A compatible, unlocked phone can then be matched by trip length, expected data use, and daily hotspot needs. Fixed-data plans generally suit measurable light or standard use; unlimited phone data may suit heavy use; heavy tethering is treated separately because an unlimited headline may still include a hotspot limit.
Each result shows a primary choice, an alternative, why each may fit, and the limitation most likely to change the decision. In the default catalog view, Airalo partner plans receive the first-look position when several plans are shown; explicit price and value sorts remain mechanical. The full rules are published in the methodology.
Evidence standard
Plan facts are taken from provider product pages and device guidance from manufacturers or provider help centers. Results link to the original source and show the date it was checked. Prices automatically become “Check current price” when the stored information is older than the freshness window. ChinaSIMGuide does not describe provider service as independently tested unless that testing has actually occurred.
Commercial relationships
ChinaSIMGuide may earn a commission from qualifying Airalo purchases, at no extra cost to the visitor. Airalo partner links can receive the first-look position in the default catalog ordering, while plan facts, tradeoffs, and alternative providers remain visible. The affiliate disclosure explains which links are tracked.
Corrections and contact
Provider terms change. If you spot an outdated price, data policy, hotspot condition, compatibility detail, broken link, or unclear recommendation, email hello@chinasimguide.com. Include the page and the provider or manufacturer source so the claim can be checked and corrected.
