Quick verdict: Mobile proxies route your traffic through real 4G / 5G carrier IPs. Carrier-grade NAT (CGNAT) puts thousands of real phones behind each public IP, so blocking the IP would block thousands of legitimate users — carriers rarely allow that and platforms know it. Residential proxies route through real home broadband IPs from ISPs like Comcast or BT, also high-trust, but easier to ban once a platform has fingerprinted bad behavior on the specific household IP. Mobile = highest trust + highest price; residential = high trust + best pool size.
| Residential | Mobile (4G/5G) | |
|---|---|---|
| IP source | Real home broadband (Comcast, BT, etc.) | Real mobile carriers (Verizon, Vodafone, EE, etc.) |
| Device behind IP | One household, 1–30 devices | Hundreds to thousands of phones (CGNAT) |
| ASN type | Residential ISP | Mobile carrier |
| Trust score | High | Highest |
| IP pool size (2026) | 10M–130M+ rotating | 1M–55M rotating, or per-IP dedicated |
| Speed | 50–500 Mbps | 20–500 Mbps (4G) / 100–2,000 Mbps (5G) |
| Price (2026) | $1.75–$2.75/GB | $2/IP/month dedicated or ~$3.50/GB rotating |
Carrier-grade NAT is the single most important fact about mobile proxies. When Vodafone or T-Mobile assigns a public IPv4 to a tower, that IP is shared by hundreds to tens of thousands of phones in that geographic area. If a platform bans the IP, it bans every legitimate phone on it — tourists, customers, businesses. So platforms tread carefully on mobile IPs: they soft-flag, throttle, or shadow-ban, but rarely hard-block.
Residential IPs sit behind a much smaller NAT — one household, sometimes one device. Hard-banning a residential IP affects one family. Platforms ban residential IPs more freely.
Mobile is priced per IP (dedicated) or moderately above residential per GB (rotating). For a single account that needs the highest trust and stays low-volume (say 5GB/month of social media activity), dedicated mobile at $2/IP/month is cheaper than $2.75×5 = $13.75/month for residential.
Serious operators use both. A typical stack:
5G mobile proxies are faster (100–2,000 Mbps vs 4G's typical 20–500 Mbps) and add a few-percentage-points of "we're a newer device" signal to fingerprints. For most use cases — account login, slow drip activity, ad verification — 4G is plenty. See our 5G vs 4G mobile proxies deep-dive for the full breakdown.
Because thousands of users share a single mobile public IP, sessions are short. Your IP can change mid-session simply because the carrier reassigned NAT — this is normal mobile behavior, but it breaks sticky-cookie sessions. Two workarounds:
| Use case | Pick |
|---|---|
| Volume web scraping | Residential |
| Instagram / TikTok accounts | Mobile (dedicated) |
| Sneaker bots | Mobile (dedicated) |
| SEO rank tracking | Residential |
| Ad verification (desktop) | Residential |
| Ad verification (mobile) | Mobile |
| Sneaker bots | Mobile (dedicated) |
| Cheapest bandwidth | Residential |
| Highest possible trust | Mobile |
