Mobile vs Residential Proxies

Both types use IPs that belong to consumer networks, so both usually pass the IP-type checks that stop datacenter proxies. They differ in how many real people share each IP, which changes how sites treat them, and in speed and price.

Both run over HTTP, HTTPS and SOCKS5, with rotation on every request or sticky sessions from 30 s to 36 h: one dashboard, one balance.

Pool sizes by country (ProxyField):

Mobile networks are the carriers whose networks the mobile IPs run on; you choose the country, region and city.

Usually not: they are sold and priced as separate types, because they run on different networks. A residential IP belongs to a home broadband provider and usually serves one household; a mobile IP belongs to a cellular carrier and is shared by many phones. The confusion comes from the fact that both are consumer IPs rather than datacenter IPs, so some providers group mobile under a broad "residential" heading, and "4G residential" usually means a mobile proxy sold under a residential label.

Ask any provider whether an IP comes from a carrier or a home ISP, then check it yourself: request https://api.ipify.org through the proxy, then look the IP up in any IP lookup service and read who owns its network (the ASN).

curl -x gate.proxyfield.io:7000 -U "<login>-country-us-city-new_york:<password>" https://api.ipify.org

Check a few exits, not one: a single lookup can be wrong for some ranges.

Mobile carriers have far more subscribers than public IPv4 addresses, so they put many phones behind each public IP with carrier-grade NAT (CGNAT). The IETF set aside a separate address range for exactly this, the shared address space 100.64.0.0/10 that carriers use between subscribers and their NAT (RFC 6598). The result: at any moment, one public mobile IP may carry traffic from many real people.

For a website, that changes the cost of a block. Blocking a datacenter IP rarely hurts a real user; blocking a home IP hurts one household; blocking a mobile IP can lock out many real customers at once. Cloudflare says this outright: IP block-listing "would result in blocking legitimate traffic from residential networks", a problem it describes as worse on mobile networks behind CGNAT, so it classifies proxy traffic per request with "behavioral and latency-based features" instead (Cloudflare, June 24, 2024).

Residential IPs get most of the same benefit: they are registered to consumer ISPs and scattered across many networks. The difference shows on the strictest targets, mostly social media and mobile apps, where even a clean home IP can be challenged and a mobile IP is challenged less often.

A mobile IP is still only one signal. As the Cloudflare example shows, sites also read behavior, browser fingerprints, cookies, account history and request patterns, so a scraper that sends too many requests or a mismatched browser profile gets challenged on any IP type.

Residential proxies are usually faster. Mobile networks add radio latency, and speeds vary with the signal and the load on the cell. ProxyField residential proxies have an under 1 s typical response and mobile proxies an under 1.5 s typical response, according to our service data.

5G helps: it has lower latency and more bandwidth than 4G where coverage is good. But a proxy's speed also depends on the distance between the exit and the target and on the provider's routing, so a 5G label does not make a mobile proxy faster than a nearby home connection.

The label names the radio generation of the network the IP runs on. For a website, all of them are carrier IPs; the label matters for speed and for which IPs are available.

• 3G is being switched off by many carriers; little proxy traffic runs on it today.
• 4G and LTE mean the same thing in practice: LTE is the standard behind most 4G networks. This is where most mobile proxy IPs sit.
• 5G has lower latency and higher throughput where coverage is good. An IP lookup shows the carrier that owns the IP, not the radio generation, so a site sees a 5G IP as a carrier IP, like a 4G one.

ProxyField mobile proxies run on 5G, 4G and LTE carrier networks. In the United States, the mobile IPs run on networks including Verizon, AT&T and T-Mobile; per-country networks are listed on the mobile proxies page. The carrier is not a targeting option.

A phone's public IP changes when the carrier reassigns it, for example after the device reconnects to the network. Mobile proxy providers rotate IPs in one of two ways:

• A rotating pool: a gateway sends each request, or each session, through a different mobile IP from a large pool. This is how ProxyField works: a new IP on every request, or the same IP for a sticky session from 30 s to 36 h.
• A dedicated device: one modem or phone is yours, and its IP changes when you trigger a reconnect or on a timer. ProxyField does not sell dedicated device plans; mobile traffic is priced per GB.

The rotating pool gives you many IPs and cities from one endpoint; a dedicated device gives you one line you control. For most scraping and account work, the pool is simpler. The session side is covered in sticky vs rotating proxy sessions.

Mobile is worth its extra cost when its success rate on your target is higher than residential's by more than its price premium. At ProxyField, mobile is the residential price plus $0.50 per GB in every band, which makes it 17% dearer at 1 GB and 26% dearer from 1,000 GB.

When it is and is not worth it is in the table at the top; this section puts numbers on it.

The rule: what you pay for is successful pages, so compare cost per successful page, not price per GB. If pages weigh the same on both, mobile pays off only when its success rate on your target is at least the price ratio times the residential rate: 1.17 times at 1 GB, 1.26 times from 1,000 GB. The last column is a hypothetical example: if residential IPs get 60% of pages through on a target, mobile must reach about 70% to 75% to cost less per page.

A worked example (hypothetical success rates; 1,000 requests that use about 1 GB on either type, at 1 GB prices):

Here mobile is the cheaper choice: its success rate is 33% higher, more than its 17% premium. On an easy target where residential gets 950 pages through and mobile 970, residential costs $3.11 per 1,000 successful pages and mobile $3.56, so the premium buys nothing.

The tier rate applies to the whole purchase, there is no subscription, and the traffic never expires. One balance covers both, so you can send most traffic through residential IPs and only the hardest targets through mobile IPs: residential and mobile proxy pricing.

For most web scraping, residential proxies are better than mobile: cheaper ($2.95/GB against $3.45 at 1 GB, $1.95 against $2.45 from 1,000 GB) and faster (under 1 s against under 1.5 s typical response, according to our service data), and they cover price monitoring, SERP tracking and public data well. Mobile proxies are better only on the targets that challenge home IPs, mostly social media, mobile apps and mobile-only content: a mobile IP is shared by many phones, so sites block it more cautiously, which helps only where a home IP gets challenged.

A failed request is not free on either type: a block or a challenge page still downloads bytes, and those bytes count as traffic. So a mobile IP that gets challenged anyway costs twice, once for the wasted GB and once for the premium. A mobile IP alone also does not get a scraper past fingerprint or request-pattern checks.

Find out on your own target before you scale. The pilot costs $6.40:

1. Buy 1 GB of residential traffic ($2.95) and 1 GB of mobile traffic ($3.45) on the same balance.
2. Run the same list of URLs, at the same pace, through each.
3. Count successful pages, challenges and blocks, and GB used, for each type.
4. Divide the cost of the GB used by the successful pages: that is your cost per successful page.
5. Keep residential for every target where it costs less per page, and move only the rest to mobile.

The dashboard shows usage in real time, so you can read the GB used per type as the pilot runs.

The full proxy choice for scraping is on proxies for web scraping.

Start with residential proxies and move a target to mobile only if residential IPs get challenged there.

Creating accounts in bulk is not an allowed use; managing your own or your clients' accounts is.
