The United States is the single most-targeted geography for residential and mobile proxy work, so a genuine US mobile IP carries real weight. Our pools ride physical SIM hardware on the three nationwide networks — AT&T, T-Mobile and Verizon — each sitting behind carrier-grade NAT, which means the exit address looks exactly like an ordinary American smartphone on LTE or 5G. That matters when you are reaching platforms that score US traffic the hardest: ad networks, social apps and search engines all treat a real Verizon or AT&T cellular IP very differently from a datacenter range.
Which US carrier should you choose: AT&T, T-Mobile or Verizon?
All three nationwide operators behave slightly differently from a proxy standpoint, and the right pick depends on the platform you are working against. Verizon and AT&T are the long-established incumbents with the widest reach into suburban and rural America, so their CGNAT ranges read as deeply "normal" residential cellular traffic. T-Mobile, after its merger with Sprint, runs an aggressive mid-band footprint and is the carrier most associated with mainstream US T-Mobile 5G. If a target site has previously blacklisted a particular carrier's known IP blocks, rotating to a different operator is often the fastest fix — which is why having all three on tap is the practical advantage.
4G vs 5G on US mobile proxies
For most automation, raw throughput is rarely the constraint; trust and clean rotation are. Standard AT&T, T-Mobile and Verizon 4G/LTE exits are more than fast enough for account management, posting and scraping, and they are the most ubiquitous traffic profile in the US. Where T-Mobile 5G helps is bandwidth-heavy work — pulling media, large SERP harvests or high-volume verification — and on platforms that increasingly expect newer radio characteristics. You can keep the same no-KYC, crypto-paid setup on either, so pick 5G when speed matters and stick with LTE when you simply want the broadest, most unremarkable US fingerprint.

What are US mobile proxies best used for?
- Social media multi-accounting — US-based accounts on Instagram, TikTok, X and Facebook are checked against the toughest geo-trust models; a real carrier IP plus per-account stickiness keeps profiles separated. See multi-accounting.
- Ad verification — confirm how US campaigns actually render to local users across AT&T, T-Mobile and Verizon eyeballs (ad verification).
- SERP tracking and scraping — Google heavily localizes US results, so an American mobile exit returns the rankings real users see (rank tracking).
