A mobile proxy sends your phone's traffic through another device that sits on a real carrier network, such as Vodafone, T-Mobile or O2. Websites and apps then see the IP address of that device instead of your own. People use this to test how an app or ad looks in another country, to manage several social or store accounts without linking them, and to collect public data from sites that treat datacenter addresses with suspicion.
This guide explains what you need and shows two ways to set a mobile proxy up on Android: the built-in Wi-Fi setting and a proxy app.
What makes a mobile proxy different
A proxy server (https://en.wikipedia.org/wiki/Proxy_server) is simply a middleman for your connection. What matters is where its IP address comes from. Datacenter proxies use addresses that belong to hosting companies. Residential proxies use home broadband addresses. Mobile proxies use addresses that a mobile carrier hands out to phones and modems.
Carriers put many subscribers behind the same public address, a technique called carrier-grade NAT (https://en.wikipedia.org/wiki/Carrier-grade_NAT). Because one mobile IP can stand for a large number of ordinary phone users, websites are careful about blocking it. That is the main reason mobile proxies work in places where other proxy types get stopped.
What you need before you start
Your provider gives you four things: a host name or IP address, a port, a username and a password. You will also be told whether the proxy speaks HTTP, SOCKS5 or both. With a dedicated mobile proxy from a provider such as ipvolt (https://ipvolt.com), one device on a carrier network is reserved for you, and you can change its IP address on demand or on a schedule.
Keep the details at hand, and decide which method below fits what you want to do.
Method 1: the built-in Wi-Fi proxy setting
Android can send traffic from one Wi-Fi network through an HTTP proxy without any extra app. Menu names differ slightly between manufacturers, but the path is close to this:
1. Open Settings and go to Network & internet, then Internet (or Wi-Fi).
2. Tap the gear icon next to the Wi-Fi network you are connected to.
3. Tap the edit (pencil) icon and open Advanced options.
4. Set Proxy to Manual.
5. Enter the proxy host name and the port, then save.
The first time your browser loads a page, it will ask for the proxy username and password.
This method has limits you should know about. It works only for the Wi-Fi network you edited, not for mobile data. It supports HTTP proxies only, not SOCKS5. And it is mostly respected by browsers: many apps ignore the system proxy and connect directly. It is fine for checking a website in Chrome, but not for routing a whole phone.
Method 2: a proxy app for the whole device
To send traffic from all apps through the proxy, or to use SOCKS5 (https://en.wikipedia.org/wiki/SOCKS), install a proxy client from Google Play. These apps use Android's VPN slot to capture the phone's traffic and forward it to your proxy, so they work on Wi-Fi and mobile data alike.
The steps are similar in most of them:
1. Create a new profile and choose the protocol, HTTP or SOCKS5.
2. Enter the host, port, username and password from your provider.
3. Optionally pick which apps should use the proxy and which should connect directly.
4. Start the connection and accept Android's VPN request. A key icon appears in the status bar while it is active.
Per-app routing is worth using. You can keep banking and messaging apps on your normal connection and send only the browser or the app you are testing through the proxy.
Check that it works
Open your browser and search for “what is my IP”, or visit any IP lookup site. You should see the proxy's address, with the carrier's name as the provider and the proxy's country as the location. If you still see your own address, the app or browser is bypassing the proxy: check that the profile is active and that the app is on the list of proxied apps.
If your provider supports rotation, change the IP from its dashboard and reload the lookup page. The address should change while the carrier and country stay the same. Note that carriers sometimes hand back the same address, so try again after a minute if nothing changed.
A few practical tips
Use one proxy per account when you manage several accounts, so that they do not share an address. Avoid free proxy lists: you do not know who runs those servers, and they can read unencrypted traffic. Turn the proxy off when you do not need it, because every request takes a longer route and uses the proxy's data connection. And remember that a proxy changes your IP address, not what an app already knows about your account or device.
With the details from your provider and five minutes in Settings or a proxy app, your Android phone can browse from a real mobile connection in another city or country.
