AT&T: America's Most Trusted Legacy Carrier
With $122.1B in annual revenue (2024), 71.6M postpaid subscribers, and 200M+ total connections including Cricket Wireless and IoT, AT&T is a cornerstone of US telecommunications. The 2022 WarnerMedia divestiture refocused AT&T purely on connectivity — its core strength.
Subscriber Scale
71.6M
AT&T reported 71.6 million postpaid phone subscribers in Q4 2024, making it the #3 US wireless carrier by subscriber count. Including prepaid (Cricket Wireless), connected devices, and IoT, AT&T serves 200M+ total connections — generating massive legitimate traffic through AS7018 CGNAT pools.
5G Coverage Expansion
290M+
AT&T's 5G network covers more than 290 million people across the United States. C-Band (n77) deployment in 2022 brought mid-band 5G speeds to major metros. Combined with low-band n5 (850 MHz) for extended range and mmWave for dense urban cores, AT&T offers a comprehensive multi-layer 5G strategy.
FirstNet: Public Safety Network
Band 14
AT&T exclusively operates FirstNet — the nationwide public safety broadband network for first responders on dedicated Band 14 (700 MHz) spectrum. No other US carrier has this institutional responsibility. This unique role positions AT&T as critical national infrastructure, elevating the trust profile of every AT&T IP address.

Pure Connectivity Focus After WarnerMedia Divestiture
In 2022, AT&T completed the spinoff of WarnerMedia (HBO, CNN, Warner Bros.) to Discovery, forming Warner Bros. Discovery. This strategic move refocused AT&T entirely on its core telecommunications business — wireless, fiber, and enterprise connectivity. The result is a leaner, more focused AT&T investing heavily in 5G infrastructure, fiber expansion (28M+ locations passed), and network reliability. For proxy users, this means AT&T's $122.1B revenue is now 100% directed at the network infrastructure that powers your proxy connections.
Why AT&T Proxies Deliver Unmatched Trust
AT&T's unique combination of legacy ASN trust (AS7018), FirstNet institutional credibility, CGNAT architecture, and 200M+ total connections creates the most trusted carrier proxy IPs available for enterprise-grade workloads.
AS7018: The Internet's Most Trusted Legacy ASN
AT&T's AS7018 is one of the oldest Autonomous System Numbers in the global routing table, dating back to the earliest days of the commercial internet. Every major platform, CDN, and anti-bot system has decades of positive history with AS7018 IP ranges. This legacy trust advantage is irreplaceable — no newer carrier or network can replicate decades of clean routing reputation. When your proxy traffic originates from AS7018, it carries the implicit trust of one of the internet's founding networks.
CGNAT Makes Every AT&T IP Inherently Trusted
AT&T deploys Carrier-Grade NAT across its mobile network, sharing public IP addresses among thousands of concurrent mobile users. When platforms like Instagram or Amazon encounter an AT&T CGNAT IP, they know it could represent any of thousands of legitimate subscribers — making it impossible to block without affecting real AT&T customers. Combined with AS7018's legacy reputation, AT&T CGNAT IPs achieve 95%+ trust scores on major platforms.
200M+ Total Connections = Massive IP Familiarity
AT&T serves 71.6M postpaid phone subscribers, plus millions more through Cricket Wireless (prepaid), connected devices, and IoT — totaling 200M+ connections. Every major platform processes billions of legitimate requests from AT&T IPs daily. Your proxy traffic blends seamlessly into this massive volume of authentic mobile traffic, making detection statistically impossible.
FirstNet Elevates Entire Network Trust Profile
AT&T exclusively operates FirstNet — the nationwide public safety broadband network serving police, fire, EMS, and emergency services on dedicated Band 14 (700 MHz) spectrum. No other US carrier has this institutional role. AT&T's position as the nation's critical communications infrastructure provider elevates the trust and legitimacy associated with every AT&T IP address, including consumer mobile IPs used by our proxies.

AT&T's carrier-grade infrastructure, AS7018 legacy trust, and CGNAT architecture make these proxies effective across virtually every use case where enterprise-level platform trust and reliability matter.
Social Media Account Management
Manage multiple accounts on Instagram, TikTok, Facebook, X (Twitter), and Snapchat with authentic AT&T IPs. With 200M+ total connections across postpaid, prepaid, and Cricket Wireless, AT&T IPs are among the most commonly seen mobile addresses on social platforms — providing maximum trust for multi-account operations, content scheduling, and influencer management.
Ad Verification & Brand Safety
Verify digital ad placements, detect ad fraud, and ensure brand safety across programmatic networks using genuine AT&T mobile IPs. See ads exactly as AT&T's massive mobile user base sees them — critical for agencies managing multi-million dollar ad campaigns across US markets. AS7018's enterprise trust ensures verification requests are never challenged.
Web Scraping & Data Collection
Scrape Amazon, Google, Walmart, Target, and major platforms with CGNAT-protected AT&T IPs that cannot be individually blocked. C-Band 5G speeds of 150-250 Mbps support high-concurrency data collection. AS7018's legacy trust means anti-bot systems are least likely to challenge AT&T-originated requests.
E-commerce & Sneaker Bots
Secure limited-edition drops on Nike SNKRS, Shopify stores, Footlocker, and Supreme with AT&T 5G proxies. Mobile carrier IPs bypass sophisticated bot detection systems that block datacenter and residential IPs. AT&T's enterprise-grade AS7018 trust gives you a critical edge during high-demand releases.
Financial Data & Market Intelligence
Access financial data platforms, stock tickers, and market intelligence APIs with AT&T's enterprise-trusted IPs. AT&T's strong presence in the US financial sector (banking, fintech, Wall Street) means AS7018 IPs are routine traffic on financial platforms — ideal for price feeds, SEC filings, and real-time market data aggregation.
SEO & SERP Tracking
Monitor Google, Bing, and Yahoo search rankings from authentic US mobile perspectives. AT&T IPs provide genuine mobile SERP results that differ from desktop results — essential for mobile-first SEO strategies. Track local pack rankings, featured snippets, and mobile-specific SERP features across US metro areas.
Travel Fare Aggregation
Aggregate travel fares and compare prices from different regions without being blocked. AT&T proxies ensure smooth and continuous data collection for accurate fare aggregation across airlines, hotels, and rental car platforms. Airlines display different prices based on user geography and device type — authentic AT&T mobile IPs from AS7018 provide the most trusted access for US-originating searches on United, Delta, American Airlines, and budget carriers.
Enterprise & Financial Research
AT&T's enterprise heritage makes its IPs particularly effective for accessing financial platforms, corporate resources, and B2B data sources. Bloomberg, Reuters, SEC EDGAR, and financial data APIs routinely see massive AT&T traffic from enterprise customers. AS7018 IPs encounter minimal friction when accessing professional-grade data sources — an advantage unique to AT&T's enterprise-focused brand positioning.

The AT&T Network Ecosystem: Cricket, FirstNet & Beyond
AT&T's network ecosystem extends far beyond its 71.6M postpaid subscribers. Cricket Wireless, FirstNet, AT&T Mexico, and millions of IoT connections all contribute to the massive legitimate traffic flowing through AS7018.
Cricket Wireless
Cricket Wireless is AT&T's prepaid brand, operating entirely on AT&T's network infrastructure. Cricket subscribers add millions of additional users to AT&T's CGNAT pools, increasing the legitimate traffic volume associated with AS7018 IP ranges. This prepaid traffic further diversifies the user base that platforms see from AT&T IPs — making each IP even harder to distinguish from genuine consumer traffic.
FirstNet Public Safety
FirstNet is the first and only nationwide broadband network dedicated to public safety. Built by AT&T on dedicated Band 14 (700 MHz) spectrum, it serves police, fire departments, EMS, and emergency management agencies across all 50 states. AT&T invested over $100 billion in its FirstNet and broader network deployment. This institutional role makes AT&T unique among US carriers as a critical national infrastructure provider.
AT&T Mexico
AT&T operates in Mexico under the AT&T brand after acquiring Iusacell and Unefon. This cross-border presence gives AT&T a unique North American footprint. While our proxy services focus on US AT&T IPs from AS7018, AT&T's international operations demonstrate the global scale of the AT&T brand — further reinforcing the legitimacy and recognition of AT&T IPs across international platforms and services.
Best Practices for Using AT&T Proxies
While AT&T proxies offer top-tier trust and reliability, following these best practices maximizes their potential and ensures consistent results.
Platform Bot Detection Evolution
Platforms like Instagram and Amazon continuously update bot detection algorithms to identify automated traffic — even from mobile IPs.
Solution: AT&T CGNAT IPs are shared by thousands of concurrent users, and AS7018's legacy trust means anti-bot systems give AT&T IPs the most benefit of the doubt. Combined with sticky sessions and human-like request pacing, AT&T proxies maintain 95%+ success rates across all major platforms.
IP Reputation Management
Some shared CGNAT pools may accumulate negative reputation if abused by other users on the same IP range.
Solution: Our infrastructure monitors IP health in real-time and automatically rotates to clean IP pools. On-demand rotation provides instant access to fresh AT&T IPs from AS7018, and 2 free modem replacements per 24 hours ensure you always have pristine carrier IPs.
Speed Consistency Across Spectrum Tiers
5G speeds vary between C-Band metro coverage (150-250 Mbps), mmWave urban hotspots (1-4 Gbps), and low-band extended range (50-100 Mbps).
Solution: Our AT&T proxy devices are deployed in major metro areas (NYC, LA, Chicago, Houston, Dallas, Phoenix) where C-Band n77 coverage delivers consistent 150-250 Mbps speeds. We guarantee minimum speeds sufficient for all proxy workloads.
Session Persistence for Account Management
Social media platforms flag accounts that change IPs too frequently, which can occur with aggressive rotation settings.
Solution: Sticky sessions maintain the same AT&T IP for up to 24 hours — long enough for any account management session. The IP remains a genuine AT&T CGNAT address from AS7018 throughout, providing both persistence and carrier authenticity simultaneously.
General Proxy Best Practices
Limit Concurrent Sessions
Even the best proxies can be overwhelmed if you open too many simultaneous connections. Balance your concurrency to maintain stable performance on AT&T's C-Band 5G.
Rotate IPs Wisely
Frequent IP rotation helps dodge detection, but rotating too quickly may slow your workflow. Find a rotation interval that fits your project's demands while maintaining AS7018 trust.
Monitor Bandwidth Usage
Keep an eye on data consumption. Efficient data usage can lower costs and preserve bandwidth for the tasks that truly matter.
Follow Platform Policies
Make sure your use of proxies abides by the terms of service of the platforms you're accessing. This reduces the risk of account bans and legal issues.
