These are specific reviewed packages, not equivalent promises of speed or app access. Fixed and unlimited allowances have different limits.
Start with a fixed budget or daily use
Saily’s observed fixed China choices include 1 GB / 7 days at US$4.49, 5 GB / 30 days at US$15.99 and 10 GB / 30 days at US$26.99. Select enough data for the whole trip. Saily also sells unlimited products, but a complete selected-duration and FUP pairing was not established for this comparison.
Holafly’s quoted product has unlimited total data with operator fair-use management. Its reviewed page does not establish a numeric daily high-speed threshold. A longer validity on a finite bundle and a shorter unlimited plan solve different needs.

Install before flying and inspect access claims
Saily warns that access to its app may be limited in China. Configure it before departure. Its plan starts automatically at the destination with the line and roaming enabled, and its purchase activation window is 180 days, followed by automatic activation.
Saily’s official guidance conflicts: its China product FAQ says its virtual location can reach Google and Instagram but WhatsApp needs a VPN; its November 6 internet article says blocked apps generally work. Treat the essential-app outcome as unresolved. Holafly also promotes familiar apps, but an exact exit gateway and independent app test were not established here.

Sharing and mainland coverage
Saily permits tethering from the fixed bundle, using the same allowance. Holafly’s China sharing limit is 1 GB daily. Neither permission establishes a working remote-office connection on every device.
The selected packages cover mainland China; Saily explicitly excludes Hong Kong and Macao. The named networks are China Telecom/China Unicom for Saily and CMCC for Holafly. A regional trip needs a separately verified destination list, and network names alone do not establish coverage or speed at your hotel.

Where Roamzo is an alternative
Roamzo operates this website. Its reviewed fixed 10 GB / 30-day bundle is US$11.99. Roamzo’s confirmed technical catalog establishes hotspot support, Hong Kong traffic exit and compatible same-profile data reloads. Its seven-day Unlimited total is US$10.49, subject to operator speed management; no numeric high-speed threshold is published here. Compare those conditions before treating the lower totals as equivalent.
The broader list also includes ByteSIM 10 GB / 7 days at US$8.90 and MobiMatter’s TSimTech regional 10 GB / 30 days at US$9.99. They keep the comparison wider than these three brands, with their own validity, coverage and reload restrictions.

What should decide this comparison
Use a fixed bundle when your estimated total fits it and the longer validity matters. Consider an unlimited product when its daily restrictions fit your use. If WhatsApp or another service is essential, resolve the provider’s exact China access guidance before purchase. Our evidence review cannot settle that question through a brand-wide winner.

Roamzo owns this website. Its price and supported features can be useful for a mainland-only trip; regional coverage, fixed versus unlimited data, and the exact policies still need to fit your itinerary. See the full Roamzo China guide, or compare all 12 reviewed providers.
