Cloud Phone + Coronium — native app workflow pattern
BitBrowser's Cloud Phone runs Android apps in a virtual environment with full SIM/carrier simulation. By default it uses BitBrowser's built-in egress; for end-to-end mobile-IP authenticity, route through Coronium.
Cloud Phone fits these workflows
- •TikTok native app (uploads, livestreaming) where browser-based workflows hit limitations.
- •Instagram Reels native upload (better quality + algorithm signals than mobile-web upload).
- •Banking / fintech apps with native-only authentication.
- •App-store reputation building (real device + real mobile IP = higher app trust).
Common errors & fixes
| Error | Fix |
|---|---|
| "Proxy test failed" | Match SOCKS5/HTTP to Coronium port. Test with curl first. |
| "Authentication required" | Wrong creds OR whitelist auth missing. |
| Cloud Phone not using proxy | Cloud Phone needs separate proxy assignment from regular profiles. |
| Free tier limit hit | 10 profiles is the cap. Upgrade to $10/mo for 50 profiles. |
| Bulk CSV import failed | Confirm column names match BitBrowser format. UTF-8 encoding. |
| Local API connection refused | BitBrowser desktop app must be running. Check API port (default 54345). |
