Which countries can I use, and how many devices are online?

Mobile 4G/5G runs in the countries listed with live availability on the locations page. The counts on this page come straight from our stock endpoint and are labelled "online now"; when the endpoint does not answer we show no figure at all rather than an old one. Pools are shared between customers and change through the day, so read the count before a large run.

Can I buy proxy traffic as I need it?

Yes. Buy a GB amount before you use it and add more when needed. The price per GB is set by the size of each order, and one balance covers both shared pools. GB never expire. What you buy stays on your balance until you use it; a new purchase adds to the same balance. The table on this page shows the rates; checkout confirms your order total.

How does rotation work, and what does a sticky session guarantee?

Rotation is a token in the username: per-connection selection with rot-ondemand (addresses can repeat), a timer of 5, 10, 20 or 60 minutes with rot-auto5 to rot-auto60, or a named session with sid and rot-sticky. A sticky session keeps the same device. The carrier may still change the IP of that device. We do not sell fixed IP addresses on this product, and the pools are shared.

When should I choose Mobile 4G/5G rather than Residential?

Choose Mobile 4G/5G when any of these is true. You are testing how your own product responds to a visitor using a carrier-network connection. You are checking permitted ad or page content from a mobile-network exit, with the device and browser settings your test requires. Otherwise: choose residential when the job calls for a peer-network connection or a country currently available in that pool. Compare the live country lists before planning the job. Switching pools uses the same balance and credential.

What may I not use it for?

The lawful jobs we sell for are price and marketplace monitoring, ad verification, market research, QA and geo-testing, and AI agents and data pipelines. We refuse social multi-accounting, sneaker and ticket bots, betting arbitrage, sybil airdrop farming, bonus abuse, credential stuffing, and anything against the law of the exit country. You accept the acceptable-use policy at every checkout, and up to 50 GB per rolling 30 days needs no company verification.

What you are buying

How mobile 4G/5G traffic reaches a site.

Your client opens a normal HTTP or SOCKS5 connection to our gateway. The gateway reads the username, picks a modem in the country you named, and forwards the request out of that modem. The answer comes back the same way. Nothing is installed and nothing is reserved for you: the pool is shared, and a modem serves whoever asks for that country next.

Where the traffic comes from

Mobile traffic runs on carrier modems operated by our network partner; residential traffic runs on opt-in peer devices in the partner network.

We never list the exit IPs of a pool. How we source traffic →

Shared pool

What “shared” means in the mobile 4G/5G pool.

What is shared

Many customers use this pool at the same time, and the device behind your connection can also carry other customers’ traffic. The gateway picks one of the carrier modems online that match your country setting; your rotation setting decides how long your connections stay on it.

What is not promised

No device or address is reserved for you, and we do not sell fixed IP addresses on this product. A device online now can disconnect. A sticky session keeps the same device. The carrier may still change the IP of that device.

Why you pay per GB

Because nothing is held for you, the price follows the traffic your connections carry, counted at the gateway. The price per GB depends on order size, and one balance covers both pools.

Rotation and protocols

Choose the exit behaviour in the username.

Rotation modes and the username token that selects each one
Mode	Token	What it does
Per-connection rotationThe gateway selects an exit for each connection. Addresses can repeat; use this mode when no continuing proxy session is needed.	rot-ondemand	The gateway selects an exit for each connection. Addresses can repeat; use this mode when no continuing proxy session is needed.
Timed rotation: 5, 10, 20 or 60 minutesThe exit changes on a clock rather than per request. auto10 is the default when no rot token is given.	rot-auto5 · auto10 · auto20 · auto60	The exit changes on a clock rather than per request. auto10 is the default when no rot token is given.
Sticky sessionThe same session name returns to the same device while it is online. A sticky session keeps the same device. The carrier may still change the IP of that device.	sid-<name> + rot-sticky	The same session name returns to the same device while it is online. A sticky session keeps the same device. The carrier may still change the IP of that device.

When to use rotating IPs or sticky proxy sessions.

Two protocols, one credential

HTTP CONNECT on port 7000 and SOCKS5 on port 7001, same username and password. In clients such as curl, socks5h sends the destination hostname to the proxy for resolution.

Choose between HTTP and SOCKS5, or check SOCKS5 compatibility before buying.

Many connections at once

One credential serves many parallel connections and sessions, with no fee per connection. The gateway answers 429 when your account limit is reached; the limit is in your dashboard.

When a country is empty

A country with no device online answers 502 with E_NO_STOCK_COUNTRY rather than sending you somewhere else. Retry shortly, or pick another country.

Connect in one commandsh

# HTTP on port 7000: pool "mbl", country "nl", timed rotation every 10 minutes
curl --disable --silent --show-error --noproxy '' --connect-timeout 5 --max-time 15 -x "http://gw.portproof.org:7000" \
  --proxy-user "USERNAME-mbl-nl-rot-auto10" \
  "https://api.portproof.org/v1/echo-ip"

# SOCKS5 on port 7001, per-connection rotation (addresses can repeat)
curl --disable --silent --show-error --noproxy '' --connect-timeout 5 --max-time 15 -x "socks5h://gw.portproof.org:7001" \
  --proxy-user "USERNAME-mbl-nl-rot-ondemand" \
  "https://api.portproof.org/v1/echo-ip"

# a sticky session: reuse the selected device while it remains available
curl --disable --silent --show-error --noproxy '' --connect-timeout 5 --max-time 15 -x "http://gw.portproof.org:7000" \
  --proxy-user "USERNAME-mbl-nl-sid-cart7-rot-sticky" \
  "https://api.portproof.org/v1/echo-ip"

Replace USERNAME with the account part of your username from the dashboard after a fulfilled purchase. Choose one example in an interactive terminal and enter your password when curl prompts. Use a country with devices online now in this pool; a country page alone does not confirm availability. The transfer timeout does not set a deadline for entering the password.

Test the connection with curl for response checks and troubleshooting, or use the setup reference for username tokens and Python, Node and Playwright snippets.

Questions

Answers before you buy.

What is a mobile proxy?: A mobile proxy routes your request through a 4G or 5G modem on a mobile network, so the destination sees a carrier address instead of a data-centre one. Mobile traffic runs on carrier modems operated by our network partner; residential traffic runs on opt-in peer devices in the partner network. You connect to our gateway over HTTP or SOCKS5 and name the country in the username; nothing is installed on your side.
Which countries can I use, and how many devices are online?: Mobile 4G/5G runs in the countries listed with live availability on the locations page. The counts on this page come straight from our stock endpoint and are labelled "online now"; when the endpoint does not answer we show no figure at all rather than an old one.
