Cheapest Mobile Proxy: What It Actually Costs

The cheapest mobile proxy is whichever billing model matches your traffic shape, not whichever provider prints the lowest headline number. Pay-per-GB is cheapest for light, bursty work where you may use a fraction of a gigabyte in a month. A dedicated 4G/5G device is cheapest once your monthly traffic is large enough that per-GB billing exceeds a flat monthly fee, and it is the only option when you need one stable IP that nobody else touches.

Headline prices on comparison pages are usually a trial fee, a weekly teaser, or a per-GB rate that only applies at the top volume tier. Compare the price of the exact bundle you will actually buy.

The three ways mobile proxies are priced

Mobile bandwidth costs more per gigabyte than residential or datacenter because it comes from real SIMs on real carrier plans behind CGNAT. Anything priced far below the market for "mobile" is usually residential traffic relabeled, or a pool sourced from users who did not knowingly opt in. Why cheap residential proxies are often unethical IP traps covers how that sourcing works and what it does to IP reputation.

How much does a mobile proxy cost?

VoidMob's shared pool is GB-denominated with volume discounts: $3.99 for the entry package at $3.99/GB, $35 at $3.50/GB, $81.25 at $3.25/GB, $149.50 at $2.99/GB, and the largest package at $250, which works out to $2.50/GB. Dedicated devices are monthly, per country, with two tiers each, starting from $49/month in the cheapest countries and rising with carrier cost: Moldova from $55, Ireland, Lithuania, Poland and Thailand from $59, the United Kingdom from $97, Germany from $119, the United States from $129.

Two things follow from that structure. First, the per-GB price drops as the package grows, so buying the volume you will genuinely consume within the period is cheaper than repeatedly topping up the smallest package. Second, geography changes the dedicated price a lot and the pool price not at all: if your work does not require a specific country, targeting a cheaper one on a dedicated device is the single largest saving available.

The break-even rule

Divide the monthly price of the dedicated device in your target country by the per-GB rate of the pool package you would otherwise buy. That gives the monthly traffic at which the flat fee wins. Below it, pay-per-GB is cheaper. Above it, the device is cheaper and you also stop paying for rotation you do not want.

Apply three corrections before you trust the result:

• Retries bill twice. A blocked request still consumes bandwidth. A workload with a high failure rate on cheap IPs can cost more per successful response than a dearer pool with clean exits.
• Rendered pages are heavy. Headless browsers that load images, fonts, video and third-party scripts can burn an order of magnitude more data than fetching HTML or hitting an API. Blocking media in Playwright or Puppeteer is usually the biggest single line-item cut.
• Concurrency is not free on one device. A single dedicated device is one IP and one uplink. If you need parallel sessions from different IPs, you need either several devices or the pool.

If most of your traffic is idle account presence rather than bulk fetching, the device usually wins early. Dedicated vs shared mobile proxies works through that trade-off in full.

Cutting cost without downgrading the IPs

• Fetch, do not render. Use the site's JSON endpoints where they exist; reach for a browser only when the page truly requires one.
• Cache aggressively. Never re-download a page you already parsed this week.
• Hold sessions instead of re-authenticating. Every fresh login costs handshake traffic and raises risk. Pin a session with _s_<id> on the flex gateway and keep it for the whole flow; see sticky sessions for how long to hold one.
• Rotate per request only where it helps. Leaving the session parameter off gives per-request rotation, which is right for independent public pages and wrong for anything logged in, where it triggers checks that cost you retries.
• Target only as narrowly as you need. City and ISP targeting narrows the device pool, which can slow a run and increase failures on thin inventory. Country-level targeting is often both faster and cheaper in practice.
• Check the exit before you spend the package. Run a few requests through the Proxy Validator and confirm the IP reports as mobile on the carrier you expect. Discovering that mid-run wastes gigabytes.

For per-account budgeting across many identities, the mobile number and proxy toolkit for multi-account automation shows how the proxy line sits next to the verification line, which is where most "cheap" setups actually overspend.

Is there a free mobile proxy?

Public free proxy lists are not mobile, and the ones that claim to be are either datacenter IPs with a spoofed label or short-lived exits already flagged by every serious detection vendor. Free VPN and proxy apps monetise differently: they resell your device's connection as an exit node, which is the opposite of what you want when you are buying one. Free VPNs and proxies aren't free breaks down the mechanics.

The honest cheap path is a small paid package on a real pool, verified before you scale. If your budget per account is genuinely tiny, read the cost section of best proxies for surveys, where the economics are tightest of any use case.
