Route your traffic through real 4G LTE mobile IPs assigned by mobile carriers. Carrier-grade NAT makes these proxies the hardest type to block — ideal for social media, multi-accounting, sneakers, app testing and ad verification.
A 4G proxy sends your requests through a genuine 4G LTE connection on a mobile carrier, so sites see a real cellular IP instead of a datacenter one. Because carriers pack thousands of users behind each IP via CGNAT, these IPs earn the highest trust and are extremely hard to block — making 4G proxies the go-to choice for account management, sneakers and ad verification.
A 4G proxy is a proxy whose exit IP comes from a real 4G LTE mobile network rather than a server farm. When you connect, your traffic leaves through a phone-style cellular connection, and the destination website records a carrier IP address — the same kind of address billions of people browse from every day.
That single detail changes everything for detection. Datacenter and hosting IPs are published in well-known ranges that anti-bot systems flag on sight. 4G LTE ranges, by contrast, belong to consumer mobile networks, so they carry mobile-grade reputation out of the box.
4G proxies sit alongside 5G proxies in the mobile family. 4G LTE offers a perfect balance of stability, coverage and cost, which is why it remains the workhorse for most automation and account work. Need a head-to-head on speed and latency? See our 4G vs 5G comparison.
The secret behind 4G proxy trust is carrier-grade NAT, the way mobile networks share a scarce supply of public IPv4 addresses across their entire subscriber base.
Carriers route hundreds to thousands of real subscribers through each public IP using CGNAT. Your proxy traffic blends into that crowd of genuine mobile users.
If a site bans a 4G LTE IP, it bans every paying customer behind it. So anti-bot systems like Cloudflare and DataDome give mobile ranges the highest trust scores.
Carriers reassign IPs as devices reconnect or move between towers. Trigger a rotation (airplane-mode style reassignment) and you get a fresh, clean carrier IP instantly.
Why it matters: the same CGNAT layer that frustrates network engineers is exactly what makes 4G proxies so resilient. You inherit the reputation of an entire carrier's subscriber base. Learn more about how trust is scored in our proxy IP reputation guide.
Our 4G proxies run on genuine 4G LTE carrier connections — not WiFi-fed devices masquerading as mobile, and not relabeled datacenter IPs. That authenticity is what drives high success rates on the toughest platforms.
4G is also part of a broader pool. We pair mobile with a residential proxy network (expanding now) so you can mix mobile-grade trust for protected targets with wide residential coverage for high-volume jobs. Many teams use mobile as a complement to residential and switch based on the target.
Pricing is refreshingly simple: pay per GB from $4/GB, dropping to $2.40/GB at volume. Endpoints are free, rotation is free, there are no monthly fees, and your GB never expire. For AI agents we also expose an MCP server and x402 USDC payments so autonomous workflows can buy bandwidth on demand.
Anywhere mobile-grade trust beats raw speed, 4G LTE proxies shine.
Run and warm multiple Instagram, TikTok, Facebook or X accounts on sticky carrier IPs that look like ordinary phones.
Mobile-grade trust helps you check out on limited Nike, Adidas and retail releases where datacenter IPs get instantly banned.
QA geo-locked features, paywalls and onboarding flows from real 4G LTE connections in the markets you serve.
See exactly what mobile users see — verify creatives, landing pages and affiliate flows without cloaking distortions.
Collect data from platforms that aggressively block hosting IPs while keeping success rates high.
Pull country-accurate pricing, search results and content from 90+ markets on genuine carrier IPs.
Mobile IPs change as carriers reassign addresses — and you control when. Rotate on every request for scraping, on a timer, or via an API call that mimics an airplane-mode reconnect to force a fresh carrier IP.
Need stability instead? Hold a sticky session to keep the same IP for the life of a login, checkout or multi-step flow. Compare the two approaches in our rotating mobile proxies guide.
How 4G LTE proxies compare to the other main proxy types.
| Proxy type | Trust | Speed | Block resistance | Best for |
|---|---|---|---|---|
| 4G LTE (this page) | Highest | Good | Excellent | Accounts, sneakers, ad verification |
| 5G mobile | Highest | Fastest | Excellent | Speed-sensitive mobile tasks |
| Residential | High | Good | Good | High-volume scraping, geo coverage |
| Datacenter | Low | Fastest | Poor | Unprotected sites, raw speed |

No port fees, no monthly minimums, no expiring data. Pay only for the bandwidth your 4G proxies use.
A 4G proxy routes your traffic through a real 4G LTE connection on a mobile carrier network. Your requests exit from a genuine cellular IP assigned by the carrier, so target sites see ordinary mobile-user traffic rather than a datacenter or hosting IP.
Mobile carriers place thousands of subscribers behind a single public IP using carrier-grade NAT (CGNAT). Blocking that IP would also block real paying customers, so sites and anti-bot systems treat 4G LTE ranges with the highest trust and almost never hard-block them.
Carriers naturally reassign mobile IPs as devices move between towers or reconnect. With PROXIES.SX you can rotate on demand, on a timer, or hold a sticky session for as long as a task needs. A fresh carrier IP is just one request away.
Common use cases include social media account management and multi-accounting, sneaker and retail drops, mobile app testing, ad verification, and any task where mobile-grade trust matters. They consistently outperform datacenter proxies on protected platforms.
You pay per GB at a flat $4/GB that drops to $2.40/GB at volume. Endpoints, IP rotation and support are free, there are no monthly fees, and your GB never expire. You only pay for the bandwidth you actually use.
Spin up genuine 4G LTE carrier IPs in 90+ countries, pay only for the GB you use, and keep your bandwidth forever.
