Unlimited Proxy: What It Means and What to Buy

An unlimited proxy is a plan that is not metered per gigabyte: you pay for a time window, not for traffic. Two different products share the name. One is a free consumer VPN app marketed as an "unlimited proxy"; the other is real proxy infrastructure billed per day, week or month. Only the second one is configurable.

The two things called "unlimited proxy"

Consumer VPN apps. Most results for this query are mobile or Chrome apps that tunnel all your traffic through a shared server. There is no username, no port, no rotation control, no geo parameter. You cannot point a scraper, an antidetect browser profile or a bot at them, and the exit IPs are shared VPN ranges that platforms classify on sight.

Unmetered proxy plans. Here "unlimited" describes billing: bandwidth is not counted, so the bill does not move with usage. On mobile networks this means renting a real 4G/5G device for a term instead of buying a gigabyte package from a shared pool. You get credentials, a port, and control over when the IP changes.

If your goal is browsing region-locked content on a phone, the first category is what you want. If your goal is automation, scraping, or running accounts, only the second one works.

Free unlimited proxy apps: what you are actually paying

Free unmetered bandwidth has to be funded. The usual models are advertising, selling browsing telemetry, or enrolling your device as an exit node for someone else's proxy network, which routes strangers' traffic through your IP. Free VPNs and proxies aren't free walks through how that resale works and how to spot it in an app's privacy disclosure.

Practical consequences, independent of the business model:

• The exit IP is shared by thousands of users, so its reputation is already spent. Check any candidate IP against a blacklist lookup before trusting it.
• Sign-ups, logins and checkouts fail more often than plain browsing, because those are exactly the flows that score IP type.
• WebRTC and DNS leaks are common in browser extensions, which defeats the point of the tunnel.

Unmetered vs pay-per-GB: how to decide

The decision is arithmetic, not preference. Metered pools scale with traffic; time-based devices do not.

VoidMob's shared tiers run from $3.99 for 1 GB down to $2.50 per GB at the 100 GB tier ($250). Dedicated devices start at $49 per month, and the United States starts at $129. Put those side by side: at the best per-GB rate, $49 buys roughly 20 GB and $129 buys roughly 50 GB. Above that monthly volume in a single country, the time-based device is the cheaper unit, and it stops being a variable cost at all.

So the rule is simple. Estimate monthly gigabytes first, then pick the billing model, not the other way around.

If your workload is research-scale crawling across many markets, the bandwidth math and the geo spread pull in opposite directions; Best Proxies for Market Research in 2026 works through that trade-off in full. For the mechanics of pool versus device, see dedicated vs shared mobile proxies.

The limits that survive "unlimited"

Unmetered removes one ceiling and leaves the rest in place. This is the part app store listings never mention.

• Throughput. A dedicated device is one radio on one cell. Peak speed is whatever that tower gives at that moment, and it varies through the day. Unmetered does not mean fast.
• Concurrency. Hundreds of parallel threads through a single device produce a request pattern no phone generates. The realistic limit is set by plausibility, not by your bill.
• Rotation cadence. On a device you own the rotation trigger, so sessions stay sticky until you rotate. Holding one IP for days looks less like a phone than rotating every 30 to 120 minutes does. See sticky sessions for how to size the window.
• IP history. Unmetered bandwidth does nothing for an IP already flagged by your target. Validate before you run volume.

Setting up an unmetered mobile proxy

1. Pick the country and term. Dedicated devices are ordered per country with daily, weekly or monthly terms and standard or premium tiers. Browse what is available on the mobile proxies page.
2. Take the connection details the API returns for that device. They are issued per device, so do not copy an endpoint out of an older tutorial.
3. Test the exit before wiring anything up. Run the credentials through the Proxy Validator and confirm the IP reports as mobile, in the right country, on the carrier you expected.
4. Set your rotation trigger. Rotate on your own timer or API call at the end of each session, not mid-flow.
5. If you also keep a metered package for burst work, the pool gateway takes geo and session as username parameters:

curl -x "http://<username>_c_US_s_run1_ttl_30m:<password>@proxy.voidmob.com:10092" https://ipinfo.io/json

Those flex credentials come from POST /v1/proxies/:id/flex_credentials in the dashboard API; drop the _s_ parameter for per-request rotation.
