Effective 11 November 2026. Best eSIM for China is operated by Roamzo. Contact hello@roamzo.app about this notice or personal information you have sent us.
The planner works in your browser
The planner uses trip duration, a usage preset and itinerary choices to calculate a data estimate and filter the published offers. It does not ask for an account, passport, phone identifier or payment details. We do not offer a contact form, collect payments or process government arrival cards on this website.
Optional Google Analytics
Google Analytics stays off until you choose Allow analytics. Before that choice, we do not load the Google tag or send analytics events. Your choice is stored in this browser under the local-storage key china-esim-analytics. This preference is separate from Google’s analytics cookies.
If you allow it, Google Analytics measures page views, completed planner matches and outbound Roamzo clicks. Events use fixed, non-personal categories such as the source site, public page, language and link placement. We strip URL query strings and fragments from the page address sent to analytics, send only the origin of a referring site, and do not send form text or private phone identifiers.
Google can set analytics cookies, including cookies beginning with _ga, and process technical information needed to provide analytics. Advertising storage, advertising personalization and Google Signals are disabled in this implementation. The site has its own analytics property, separate from other network sites. Event and user data retention is configured to two months, with retention reset on new activity off.
Open Analytics preferences in the footer to keep tracking off or withdraw consent. Withdrawal removes this site’s accessible Google Analytics cookies and reloads the page with analytics disabled. It does not retroactively erase data already processed by Google. See Google’s privacy policy for its processing and international data-transfer information.
Hosting and connection requests
Railway hosts the website and handles network requests needed to deliver it. Hosting infrastructure may process connection information such as IP address, request URL, timing and user-agent details. We do not maintain a separate persistent application log of your planner selections. Infrastructure processing is distinct from optional Google Analytics.
Links to providers and government services
Roamzo links include fixed campaign parameters identifying this source site, link placement, language and public page. They do not include your planner answers or personal details. A click recorded here is a referral click, not confirmation of a purchase. Any purchase, account or downstream attribution is handled by the destination service under its own terms and privacy notice.
Official government form links go directly to the stated authority. When you leave this website, the destination’s data practices apply. Review them before entering passport, identity or payment information.
Messages and privacy requests
If you email us, the message and your email address are handled by Roamzo to answer your request and investigate corrections. Do not include passport images, payment-card details or installation credentials. Ask us to correct or delete a message by contacting hello@roamzo.app; we will explain any applicable retention requirement or limitation.
