AT&T Mobile Proxy Lines, One or Many per Account

An AT&T line is a SIM from AT&T Mobility in a device we run in one of our US metros, assigned to your account alone for its term. A team can hold one AT&T line or a column of them, each its own row in the dashboard with its own credentials, rotation link and renewal. This page is the operational briefing on AT&T specifically: how its addresses are identified, where they geolocate, how rotation behaves, and what to think about when several of your lines are on AT&T.

Identifying an AT&T address

Lookups show the owner as AT&T Mobility LLC with autonomous system AS20057, connection type mobile or cellular. That is what a website sees for any AT&T phone in the region and what it sees for your line. AT&T assigns public IPv4 addresses behind carrier-grade NAT, so the address is shared with many AT&T subscribers at the same time; nothing about it identifies your line in particular. A fleet of AT&T lines in one metro draws from the same regional AT&T range, so over weeks the lines will see overlapping addresses.

Where AT&T addresses geolocate

State and country are reliable: an AT&T line in Houston reads as Texas, in Phoenix as Arizona, in Miami as Florida. City is usually the metro or the metro area. The exception every AT&T customer should know is Boston: AT&T routes New England traffic through its New York gateway, so an AT&T line in our Boston rack geolocates as New York on lookups. It is physically in Boston and behaves like a Boston device in every other respect; if the reading on lookups must say Boston, choose Verizon in Boston instead.

Because AT&T city readings are otherwise steady, teams running AT&T lines across several metros get consistent state results, which is what most geo-targeting keys on.

Rotation and stickiness on AT&T

Each AT&T line has its own rotation link, dashboard button and optional timer. A rotation reconnects the SIM and AT&T assigns a fresh address from the same regional range; it completes in seconds and does not touch any other line. Left alone, an AT&T address is generally sticky for hours and often longer, which suits account work. An immediate repeat of the previous address can happen and is normal; rotate again if it matters.

For a fleet, decide the rotation rule per line and note it in the label: sticky for account lines, timer or link for sampling lines.

Metros, devices and speed

AT&T lines are available in all eight metros subject to stock: New York, Los Angeles, Chicago, Houston, Phoenix, Miami, Boston and North Carolina. At checkout you pick 4G or 5G and the device type: USB modem, cellular router or Android phone. 4G AT&T lines run up to 25 Mbps download, 5G up to 50 Mbps, and the 5G+ add-on on a 5G line brings a 70 Mbps or better average download on selected 5G lines for $2 a day, $5 a week, $15 a month or $45 per three months. Data is unmetered on every line.

Several AT&T lines on one account

Teams choose AT&T across a fleet when they want steady state-level geolocation and sticky addresses. Two things to plan for: all AT&T lines in one metro share a regional range, so for clients who must never overlap in address space, put them on different carriers; and Boston AT&T lines will read as New York, which may be useful (two New York readings from two racks) or not. Label every AT&T row with metro, client and rotation rule, and keep one profile per line in your profile browser.

Price and access per AT&T line

4G: $5 a day, $27 a week, $64 a month. 5G: $6 a day, $31 a week, $74 a month. Hourly: $2 for the first two hours on 4G or $3 on 5G, then the same per hour up to four hours, never renewing, with paid hours counting toward a day. Every AT&T line is the list price however many you hold. Access by HTTP(S), SOCKS5 with UDP, or the VLESS link on the row. Moves to other metros are free with remaining time kept.
