Mobile vs residential vs ISP proxy: which should you choose?

What the market actually looks like: P2P, ISP and mobile modems

Marketing comparisons usually set "mobile" against "residential" as if each were one homogeneous block. In the field, the technical reality is more nuanced. What providers call a "residential proxy" covers two completely different things:

1. Rotating peer-to-peer residential (P2P): your traffic passes through the computer or smartphone of a private individual who installed a bandwidth-sharing application (such as Honeygain, or SDKs embedded in free apps). The IP changes as those users disconnect.
2. Static residential (often called an ISP proxy): these are servers hosted in a datacenter, but for which the provider rents address ranges registered with consumer ISPs (such as Free, Orange, AT&T or Comcast). The speed is a server's, but the address is fixed.
3. The dedicated 4G/5G mobile proxy: a real physical SIM card in a modem or a carrier smartphone, transmitting over cellular towers and going through the carrier's CGNAT.

Understanding these three models is what lets you pick the right tool without throwing money out of the window.

Typical billing	Dedicated line (time plan or quota)	Per gigabyte of data consumed	Monthly, per IP address
Throughput and latency	30 to 120 Mbit/s, 40 to 80 ms	10 to 40 Mbit/s, very unstable latency	500 to 1,000 Mbit/s, under 20 ms
SMS reception	Yes (a real number tied to the SIM)	Impossible	Impossible

The overlooked problem of polluted residential pools

The main trap of P2P residential is address pollution. The large global residential proxy providers sell access to the same millions of addresses to thousands of customers at the same time.

In practice, the IP address of one person's router in Paris can serve an aggressive scraper at 2:00 pm, get flagged by Cloudflare or DataDome at 2:05 pm, then be handed to you at 2:10 pm to try to create a Vinted or Leboncoin account. The result: you pay for a legitimate residential address that arrives with a history already ruined by someone else.

On a dedicated 4G/5G mobile proxy, by contrast, you are the only user of the line. Mobile CGNAT drowns your activity in the flow of the carrier's millions of ordinary subscribers, and when you trigger a rotation the address you get is immediately folded back into the normal dynamics of the mobile network.

Dropping mid-flight: why P2P residential hurts accounts

If your work involves creating an account, filling in a profile, making a payment or talking to a support team, session stability is critical.

With P2P residential, the remote host can close their laptop, turn off their Wi-Fi or reboot their router at any moment. Your session drops abruptly. The provider reassigns you another IP within seconds, but from the platform's point of view your account just changed IP address and city in the middle of a sensitive action. That is one of the most damaging signals there is for antifraud engines.

On a dedicated mobile proxy, the IP stays attached until you ask for a rotation through the API or from your account. You work continuously on the same address, with no unwanted cuts.

Billing per gigabyte: the hidden cost of modern browsers

Residential proxies are almost always billed between €2 and €8 per gigabyte of data. For a light script pulling plain JSON responses from an API, that is very cheap, because a few megabytes are enough.

If you work with real or antidetect browsers (AdsPower, Dolphin{anty}, BitBrowser, Geeklark), it is another story:

• Loading one modern page, with its images, fonts, telemetry scripts and video ads, consumes between 15 and 50 MB per page visited.
• Ten open profiles browsing actively can burn 2 to 3 GB per hour.
• At €5 per GB, a day's work on P2P residential can quickly cost several dozen euros in bandwidth alone.

With a dedicated 4G/5G mobile line, you pay for access to the line for a given period. You can browse, load full pages and leave your software running without watching the meter at every click.

Realistic recommendations for your project

Each solution has its legitimate place. Here are the trade-offs that hold up in the field:

1. Choose the dedicated 4G/5G mobile proxy for:

• Multi-accounting and running sensitive profiles: marketplaces (Vinted, Leboncoin), social networks and ad platforms (Instagram, TikTok, Facebook Ads), but also streaming services and online games (Spotify, Dofus, WoW). The CGNAT effect protects your accounts by avoiding the preventive blocks triggered on addresses judged suspicious.
• Scraping sites protected by antifraud systems (DataDome, Cloudflare): collection bots that run into permanent captchas on server IPs or polluted residential pools get a far higher success rate on a 4G/5G mobile IP, because those filters apply wider tolerance thresholds to consumer mobile networks.
• Local SEO and mobile SERP auditing: checking Google result pages exactly as a French user browsing on their smartphone sees them, with the real local packs, Google Business listings and geotargeted ads that mobile lines get.
• Full control over rotation (the middle ground between P2P and ISP): P2P residential cuts out without warning if the individual switches their computer off. ISP residential does not cut out, but its IP is frozen for life: if one service blocks it, your proxy becomes unusable. A dedicated mobile line combines both strengths: an address that stays stable as long as you need it, renewable instantly by a radio disconnect as soon as you switch account or target.
• SMS account validation: activation codes (OTP) arrive directly on the real mobile number tied to the SIM card, which avoids the automatic rejection of virtual VoIP numbers.
• Heavy automation on real browsers: running antidetect profiles or tools like Playwright and Puppeteer without paying per gigabyte, which is what keeps images, scripts and video streams from blowing up the bill.
• "Doing anything is how you become anyone": The catchphrase of Rémi Gaillard, a French prankster who became famous in the 2010s, sums up the mechanics of CGNAT rather well. By using a 4G/5G mobile proxy, you technically take on the appearance of any French internet user on a national carrier's network. Against the systematic tracking of fixed IP addresses and servers, a mobile proxy lets you take back control of your network presence: to the platforms, you are no longer an identifiable address or a hosting provider, but one ordinary consumer subscriber among millions. Tomorrow, why not be a Parisian on the networks?

2. Choose the rotating residential proxy (P2P) for:

• Large-scale distributed scraping of public sites (pulling millions of pages from Amazon, directories or price comparison sites).
• Very precise geographic targeting abroad, for example to test an ad display in a specific city in the United States or Japan, where shipping a local mobile modem would make no economic sense.
• Ultra-light API scripts, where data usage is so low that the per-gigabyte model stays cheaper than a monthly dedicated line.

3. Choose the static residential proxy (ISP) for:

• Routine office tasks that flatly refuse server IPs, but that need fiber transfer speed (downloading heavy files, continuous administration).
• One caveat: a fixed ISP IP does not benefit from the collective tolerance of mobile CGNAT. If a platform blocks it once, it is blocked for good.

FAQ

Does a mobile proxy make it easier to get past Cloudflare or DataDome?

Yes, on the IP reputation stage. Engines like Cloudflare, DataDome or Kasada assign a much lower default suspicion score to 4G/5G mobile ranges, because of the CGNAT they share with thousands of real subscribers. The IP is not everything, though: if your browser leaks through WebRTC or shows a suspicious software fingerprint, you will be blocked whatever the proxy type.

Aren't static residential proxies (ISP) simpler to use?

They are convenient, because the IP never changes and throughput is high. But they are often expensive per unit, offer no rotation at all when something goes wrong, and cannot receive the activation SMS that platforms send.
