Prepare the app and distinguish the products
Install the app and eSIM while you have a working connection before departure. The product describes automatic arrival activation when the line and data roaming are enabled. It allows a 180-day activation window, after which the plan activates automatically. If buying months ahead, keep that deadline with your itinerary.
The fixed bundles in this comparison are data purchases. Saily separately advertises a US number and call/text products; those features should not be interpreted as a mainland +86 number included with ordinary data. Keep a suitable phone line available for any required verification texts and check its roaming charges.

Use the mainland coverage and shared allowance
The China product names China Telecom and China Unicom and explicitly excludes Hong Kong and Macao. A cross-border itinerary needs another package with those destinations listed. Do not assume that adding more mainland data extends the same bundle across the border.
Hotspot sharing is allowed and uses the purchased allowance. Saily also offers app-based data additions and says a queued bundle starts after the current one is exhausted. Its optional automatic top-up is a separate choice. Check how the next offer will start and expire before treating it as a continuous extension of every existing term.
Resolve the WhatsApp conflict before relying on it
The China product FAQ says virtual location can provide Google and Instagram access, but WhatsApp needs a VPN. A newer official internet-in-China article describes blocked apps as generally accessible through travel-eSIM routing. Those statements do not provide a consistent exact-plan answer for essential WhatsApp use.
We therefore leave app access unverified rather than choosing the more reassuring paragraph. Ask Saily about your named package and required app. We have not tested its virtual-location feature, measured its speed or established a VPN entitlement for every fixed bundle. Security-feature marketing should not become an independent privacy guarantee.

Compare the data price without rewards or assumptions
The comparison uses the observed USD fixed-plan prices, without reward credits or a personal promotion. The storefront can localize its currency, so confirm the actual billing currency rather than comparing a euro or Swiss-franc starting price with the USD table. Unlimited offers were not added without a verified duration and applicable fair-use pairing.
Saily may fit a traveler who wants fixed data, app management and permitted sharing, and who can complete setup before entering China. It is a less settled choice when a particular restricted app is indispensable. Compare that requirement with providers whose exact routing is clearer, while still keeping an arrival-day backup and offline travel details.
