2026 Real-World Field Test

📶 Hotel & Public Wi-Fi

⚠️ FLAKY / IMAGES TIMEOUT

Accessible, but subject to throttling or auth traps.

🌐 Foreign Roaming eSIM

🟢 WORKS

Bypasses the Great Firewall via overseas telecom gateways.

Bottom Line Verdict:

Text newsletters load intermittently on Wi-Fi; images and custom domains frequently fail.

The Real Deal & Hidden Nuances

While substack.com is not consistently DNS-poisoned across all Chinese provinces, its media CDN (substackcdn.com) and custom author subdomains suffer severe packet loss and connection resets on hotel broadband. On roaming eSIMs, the Substack app streams text and audio podcasts without issue.

Recommended Action & Workaround

Read newsletters in your email client (like Apple Mail or Outlook) or switch to roaming eSIM.
