AT&T 5G With a 4G LTE Floor, Dedicated

AT&T is the third carrier on our shelves and the one to pick when the job calls for AT&T specifically: a campaign targeted at AT&T subscribers, an app that reads the carrier name, or a check that must come from the network a customer is on. An AT&T line from 5G Proxies USA is one AT&T SIM in a modem or handset we own in a US city, with 5G where AT&T has it switched on and 4G LTE underneath it everywhere. This page sets out what the address looks like from outside, how the 5G behaves, where we hold stock and what it costs.

AT&T Mobility in the lookup

An IP lookup on one of our AT&T addresses returns AT&T Mobility as the owner, under AS20057, the autonomous system AT&T uses for its wireless subscribers. The connection type is cellular. The location is the metro of the gateway that served the request, which lines up with the city where the modem sits or the state around it. There is no hosting fingerprint, because the address was never in a data center.

The address is also shared. AT&T, like the other carriers, runs carrier-grade NAT, so each public address fronts many phones at once. A site cannot tell your request from a subscriber's by the number alone, and it does not try to; it looks at behavior. On a dedicated AT&T line the only behavior behind your share of the address is your own, which is why owning the line beats borrowing addresses from a pool.

AT&T 5G where it exists, LTE where it does not

AT&T sells 5G on two layers: a low-band layer that covers wide areas and behaves much like LTE, and a mid-band layer in parts of major metros that delivers the throughput the 5G badge implies. Where our modem can register on the fast layer with a good signal, the line delivers 50 Mbps and up. Where it cannot, AT&T moves the modem to low-band 5G or to 4G LTE, and you get what 4G usually gives, 20 to 45 Mbps.

We are direct about this because AT&T's fast-layer footprint is less even across our cities than T-Mobile's. If you need the 5G tier for throughput and have no reason to prefer AT&T as a carrier, T-Mobile is usually the stronger first choice. If you need AT&T as a carrier and the throughput is a bonus, buy the 5G tier, test for a day, and keep it if the signal in that city delivers. The 4G LTE tier on AT&T is a solid, cheaper choice when the carrier name is what matters.

Our AT&T stock across the eight cities

AT&T hardware is present in all eight of our cities: New York, Los Angeles, Chicago, Houston, Phoenix, Miami, North Carolina and Boston. How many free lines there are in each changes week to week. The checkout page is live and shows what can be ordered right now; if you need several AT&T lines in one city, ask [email protected] and we will tell you where the depth is before you pay. Moving an AT&T line to another of our cities is free and keeps your remaining time, so a wrong first guess costs nothing but a few minutes.

Fresh addresses and held sessions on AT&T

Rotation is unlimited. Trigger it from the dashboard, from the rotation link in a script, from the API, or on a timer, and the modem re-registers with AT&T and returns with a new address from the regional pool. Your host, ports and credentials do not change, so nothing in your tooling needs to be updated. Sticky sessions are the default when you do not rotate: AT&T keeps the session open until it resets it, which is typically long enough for logins, uploads and multi-step flows. The carrier controls the session length, so design for the occasional change rather than against it.

When AT&T is the right pick

Choose AT&T when the carrier itself is the requirement: verifying ads bought against AT&T subscribers, testing how an app or a site behaves for an AT&T customer, confirming that content or pricing shown to AT&T users matches what was promised, or running a three-carrier comparison where AT&T is the third leg next to T-Mobile and Verizon lines. Media teams that need to see how a player adapts on a network that may be on LTE part of the time find AT&T a useful worst-case stand-in. If none of that applies and you simply want the fastest 5G we can give you, say so and we will steer you to T-Mobile or Verizon in your city.

Buying AT&T by the hour, day, week or month

An AT&T 5G line is $7 a day, $35 a week or $85 a month; AT&T 4G LTE is $6, $31 or $75. Hourly lines are available on both tiers: 4G is $2 for the first two hours and $2 per extra hour, 5G is $3 for the first two hours and $3 per extra hour, up to four hours per purchase, and an hourly purchase never renews on its own. If the hourly line runs all day, the hours you paid count toward the day price. Pay by card, PayPal, crypto, Zelle or bank wire. The line is live when the payment clears, with HTTP(S) and SOCKS5 endpoints, rotation controls and a free move between cities in the dashboard.
