Connect to your mobile proxy
Find the connection details for your rental, configure an HTTP or SOCKS5 client, verify the exit IP and understand rotation and expiry.
Use the host, port, username and password shown for your active rental. Start with one small request through the proxy, then configure your application with the same protocol and credentials.
Find the issued connection details
Sign in to the customer portal and open the active rental. Record its country, carrier, rental expiry and issued connection settings. Connection fields may differ between products, so use the details on the specific rental rather than copying an endpoint from a guide.
Keep the proxy password and any secret-bearing rotation URL in your approved secret store or a private, ignored local environment file. Do not include their values in a repository, shared workflow export, screenshot or support message.
| Field | Meaning |
|---|---|
| Host and port | The network endpoint your client connects to. |
| Protocol | Use the HTTP or SOCKS5 setting provided for that endpoint. |
| Username and password | Authentication to the proxy connection. |
| Rental expiry | When the purchased rental period ends. |
| Rotation controls | The dashboard action or URL issued for the rental, when available. |
Test an HTTP proxy with curl
Set MP_PROXY_URL in your local environment to the authenticated proxy URL using the issued HTTP endpoint. URL-encode special characters in the username and password. Do not paste a real credential-bearing URL into a public command example.
This command sends a small request to an external IP-echo service through the configured proxy. The returned public IP should be checked against a direct request and against the intended location. The result verifies this client's route at this moment; it does not prove that another application is configured correctly.
curl --fail --silent --show-error \
--connect-timeout 10 --max-time 20 \
--proxy "$MP_PROXY_URL" \
"https://api.ipify.org?format=json"Choose DNS behavior deliberately for SOCKS5
For a SOCKS5-capable curl build, the socks5h URL scheme asks the proxy to resolve the destination hostname. The socks5 scheme resolves it locally. Choose the behavior your test requires and record it when comparing clients.
Configure the issued SOCKS5 endpoint in your client. A library may require a SOCKS extra or an adapter; a field accepting an HTTP proxy URL does not necessarily accept SOCKS5. Do not assume that SOCKS5 support also establishes UDP support for the rental.
# Set MP_SOCKS_URL to the issued endpoint using the socks5h:// scheme.
curl --fail --silent --show-error \
--connect-timeout 10 --max-time 20 \
--proxy "$MP_SOCKS_URL" https://api.ipify.orgConfigure and verify the actual application
After the basic check succeeds, enter the same issued endpoint in your browser, HTTP client or automation tool. Test the route from that application itself. Environment variables, proxy bypass rules and separate browser contexts can change which requests use the proxy.
Then open a small authorized destination request. A connection working against an IP-echo service does not guarantee a destination will accept it. Record the status code and failure stage before increasing concurrency or changing the IP.
Use the rental's rotation controls
Use the dashboard control or rotation URL provided for your rental. Follow the request method and authentication documented alongside it. This page does not invent a generic public API path or assume that all products share the same interface.
Pause new work, let active requests finish where possible, request the change and wait with a deadline. Verify connectivity and the resulting public IP before resuming. The carrier may reassign an address independently, and a rotation may return an address seen earlier.
Check expiry before diagnosing an outage
Check that the rental is still active and that the connection details match the current allocation. The main checkout offers one-time rental periods; do not assume an earlier payment creates recurring renewal.
Before extending a rental or ordering again, review the options attached to the existing allocation. If payment or allocation status is unclear, contact support with the order reference, time and a redacted error. Do not repeat purchases to resolve an ambiguous order state.
