China Travel Helper publishes practical English-language information for international visitors preparing to travel in China. This policy explains how we research, write, review and update our content.
Editorial Independence
Our editorial conclusions are not determined by advertisers, affiliate partners or eSIM providers.
China Travel Helper may earn commissions from some links, but a commercial relationship does not guarantee positive coverage, a higher position in a comparison or inclusion in an article.
Providers do not receive editorial approval over our articles unless content is explicitly identified as sponsored.
Sources
We prioritize primary and authoritative sources, including:
- Official product and pricing pages
- Provider support documentation and terms
- Mobile carrier information
- Government and regulatory sources
- Official documentation from payment and travel platforms
Secondary sources and user reports may help identify practical problems, but important claims are checked against primary sources whenever possible.
Product Comparisons
When comparing travel eSIMs, we may consider:
- Price
- Data allowance
- Validity period
- Local network information
- Available network speeds
- Hotspot and tethering support
- Phone number and SMS availability
- Activation rules
- Device compatibility
- Provider statements about international app access
- Refund and fair-use terms
Plans with different data limits and validity periods are not treated as directly equivalent. Promotional prices are identified where possible, and readers are advised to confirm final details before purchasing.
We do not use precise numerical ratings when there is insufficient independent testing evidence to justify them.
First-Hand Experience and Provider Claims
We clearly distinguish between:
- Information independently observed or tested by the author
- Information published by a provider
- Information reported by users
- Editorial analysis based on available evidence
We do not describe a product as personally tested unless it has actually been used under relevant conditions.
Provider claims about coverage, speed, app access or network performance are identified as provider-reported information and are not presented as guaranteed results.
Updates
Prices, plans, application requirements and travel policies can change.
Commercial comparisons and practical setup guides are reviewed when we identify material changes. An article may display a published or updated date, but readers should still verify time-sensitive information on the relevant official website.
Corrections
If we identify a factual error, we correct it as soon as reasonably possible. Material corrections may be noted within the article when they substantially change the recommendation or conclusion.
Readers can report an error through our Contact page. Useful reports should include the relevant article URL and a supporting official source where available.
AI-Assisted Tools
We may use software tools, including AI-assisted tools, to support outlining, language editing, organization and research workflows.
Every published article is reviewed and edited by a human. AI-generated output is not treated as a factual source, and important claims should be verified against primary or authoritative sources before publication.
Affiliate Content
Affiliate links are identified through an article-level disclosure or our site-wide Affiliate Disclosure.
The presence or absence of an affiliate program does not determine whether a provider can be criticized, excluded or recommended.
