Direct Answer
To test your mobile proxy setup, verify five things: the IP a site sees, that DNS resolves through the proxy, that WebRTC isn't exposing your real IP, that the location reads as German, and that speed is stable. Each check confirms your configuration is working as intended before you rely on it.
What This Checklist Is For
These checks confirm your configuration is correct — that traffic, DNS and browser features all route through your German mobile endpoint as you set them up to. It's the same quality step you'd run after any setup: connect, verify, then build on it. Run the five checks below after first connecting, and again whenever you change tool, network or settings.
1. Check Your Visible IP
The first question: what IP does a site actually see?
- Connect through your proxy, then run our proxy checker — or open any IP-lookup service.
- Confirm the IP matches your German mobile endpoint, not your home or office connection.
- If it still shows your normal IP, the proxy isn't engaged — re-check the host, port and that the connection toggle is on.
2. Check the DNS Path
An IP can be correct while DNS still resolves locally — a DNS leak.
- Open a DNS-leak test page in the same context that uses the proxy.
- If the resolver belongs to your own provider, fix it: use
socks5h(DNS at the proxy) or route the device over OpenVPN, then re-test.
3. Check for a WebRTC Exposure
Inside a browser, WebRTC can reveal your real IP even with the proxy active — a WebRTC leak.
- Use our traffic check — it runs a WebRTC leak test — to confirm it reports your mobile IP, not your real one.
- The cleanest fix is device-level routing over OpenVPN so the browser has no separate path.
4. Check the Location
Confirm the endpoint reads as the German mobile network you expect.
- On the IP-lookup result, check the country and network/ASN — it should reflect a German mobile carrier, consistent with a real mobile connection.
- Geolocation databases vary slightly between providers; a German country result with a mobile-network type is what you want.
5. Check Speed and Stability
Finally, confirm the connection is workable for your task.
- Run a quick speed test through the proxy and note latency and throughput.
- Mobile latency is naturally higher than a datacenter link — expect that. What you're looking for is stability: consistent response times over several requests, not a single fast number. For sustained jobs, watch that sessions hold (see sticky sessions and IP rotation).
Quick Reference
| Check | Tool | Pass = |
|---|---|---|
| Visible IP | IP-lookup service | German mobile IP, not your own |
| DNS path | DNS-leak test | Resolver = proxy network |
| WebRTC | WebRTC test | Reports mobile IP only |
| Location | IP-lookup ASN/country | German mobile carrier |
| Speed | Speed test | Stable latency over several runs |
FAQ
How often should I re-test?
After any change to your tool, proxy settings or network — and periodically during long jobs. A setup that passed yesterday can drift after an update.
My IP is right but DNS leaks — is that a problem?
Yes. A correct IP with a leaking DNS path produces inconsistent signals. Move DNS to the proxy with socks5h or use OpenVPN, then re-test. See what is a DNS leak.
What's the single most important check?
The visible IP — it confirms the proxy is engaged at all. But for clean, reliable data, run all five; each closes a different gap.
