NekoBox for Android adds a node from the add button in the top-right corner. Choose HTTP or SOCKS, type the gateway host in the server field and the port in the port field, fill the username and password even though they are marked optional, save with the tick and start the node. The app opens a VPN connection that routes the phone.
Main screen → add button (top right) → HTTP or SOCKS
On the main screen tap the file icon with a plus in the top-right corner to open the node type menu.

Tap HTTP for the HTTP port or SOCKS for the SOCKS5 port. The type must match the port you will enter.

Type the gateway host in the server field and the port in the port field, then the username and password. Leave transport encryption and multiplexing off. Tap the tick in the top-right corner to save.

Select the node in the list and tap the start button. Android asks to allow the VPN connection once; accept it. Open the QuantumProxies IP checker in a browser to confirm the exit IP.

Repeat the steps with another line, for example a different country in the username, and switch between nodes from the list.

The URL test on the node, then the IP checker in the phone's browser once the node is started.
Apps on the phone now exit through the proxy. Per-app routing is in NekoBox's settings if you want only some apps on the line.
Copy the line from the dashboard (Proxies, your plan, the proxy generator) rather than typing it: it already carries the country, the session id and the session length in the username. The table shows what each field holds.
| Plan | Host | HTTP port | SOCKS5 port | Username shape |
|---|---|---|---|---|
| Residential Premium | residentialpremium.quantumproxies.io | 8080 | 1080 | USER-country-us-sid-k3f9a1b2-ttl-60m |
| Residential Basic | residentialboson.quantumproxies.io | 9000 | from the generator | USER-country-us |
| Mobile | mobile-us.quantumproxies.io (also -eu, -as, ww) | 8080 | 1080 | USER-country-us-type-mobile |
| Datacenter (per GB) | datacenterboson.quantumproxies.io | 9999 | 10000 | USER-type-datacenter-country-de |
| IPv6 | ipv6.quantumproxies.io | 1001 | from the generator | USER-country-us-package-ipv6 |
| ISP (dedicated IP) | the IP of your line | 8000 | on the plan page | the line's own login |
The password is the one the generator prints next to the username. Pick HTTP or SOCKS5 in the tool and use the port of that column; a port from the other column is the most common reason a check fails. USER and the session id are placeholders for your own values.
HTTP with the HTTP port of your plan, SOCKS with the SOCKS5 port. The server and login do not change.
Yes. Our gateways authenticate by username and password; without them the node connects but every request is refused.
Yes. The VPN connection it opens routes whichever network the phone is on through the proxy.
Skip the marketing. QuantumProxies.io publishes a machine-readable site map, Markdown for every page, a free MCP server, and APIs billed from the same balance as your proxies.
