A Day on an AT&T 4G Line, Four Dollars

Four dollars buys 24 hours on one AT&T line at 4G Proxies USA. The line is a real AT&T SIM in a modem, router or phone we own, in one of eight US cities, and for the day it carries your traffic only. This page is about the AT&T part of that: what a website learns when it looks up the address, how AT&T's LTE behaves in plain terms, where our AT&T stock is, how addresses change and stay, who tends to choose AT&T, and what the different lengths cost.

What an IP lookup shows for an AT&T line

Look up one of our AT&T addresses and the owner comes back as AT&T Mobility, under autonomous system AS20057. That is the system AT&T announces its wireless customers from, so the address reads the same as the one on an AT&T phone in someone's pocket. The connection type field says cellular. It is not a data center range, not a cloud provider, and not a home connection someone else is sharing.

The address is shared. AT&T runs carrier-grade NAT, which means one public address stands in front of many subscribers at once. A website that sees your request also sees requests from real AT&T customers on that same address during the same hour. That is why a mobile address is judged by what it does rather than by what it is, and why having the line to yourself matters: the only behavior on your line is yours.

AT&T LTE in plain terms

AT&T's 4G LTE network runs on a mix of low and mid bands. The low ones, bands 12 and 17 around 700 MHz, travel far and pass through walls, which is what keeps a modem registered inside a building. The mid ones, bands 2, 4 and 66, carry more data when the signal is good. The modem picks between them on its own, and in our cities it usually settles on a mid band with a low band as backup. On a 4G line you can expect 4G usually 20 to 45 Mbps, depending on signal at the modem. That is enough for browsing, logins, listings, ad checks and most scripted work.

If you want more, AT&T 5G is on the same checkout for a dollar more per day: 5G 50 Mbps and up, again depending on signal. Most of our customers stay on 4G because the work does not need the extra and the dollar adds up over a month.

Where we keep AT&T lines

We have hardware in New York, Los Angeles, Chicago, Houston, Phoenix, Miami, North Carolina and Boston, and AT&T SIMs are spread across all eight. How many are free in a given city changes from hour to hour as day passes start and end, so the checkout is the only honest answer to what is available right now. If you need AT&T in one specific city and it shows sold out, email [email protected]; we can say when one frees up or suggest the nearest city with stock. We do not run cities outside those eight.

Changing the address, and keeping it

A rotation drops the data session on the modem and opens a fresh one. AT&T's regional gateway then hands out an address from its pool, which may be new, or may be one the SIM has had before, and is always still AT&T in the same metro. You can rotate from the dashboard, by calling a rotation link, through the API, on a timer, or by hand, as often as you like during your day. Nobody else can trigger a rotation on your line.

Leave the line alone and AT&T keeps the address for as long as it keeps the session up. A line with a little steady traffic tends to hold its address longer than an idle one. For a session you want to keep, such as a logged-in account, keep something flowing and rotate only between jobs.

Who picks AT&T

People pick AT&T for a few reasons. The phone number on the account they manage is an AT&T number and they want the carrier to match. A site they work with happens to read AT&T addresses cleanly. Or AT&T simply had stock in the city they needed. If none of that applies to you, any of the three carriers will do the job, and the city matters more than the carrier for where the address resolves.

What an AT&T line costs

A 4G AT&T day pass is $4. A week is $25 and a month is $60. On 5G the same lengths are $5, $28 and $65. If you only need an hour or two, an hourly purchase is $2 for the first two hours on 4G and $2 for each extra hour, up to four hours, or $3 on 5G; it never renews, and if you keep the line for the full day the hours already paid count toward the $4. Every length comes with unlimited data for proxy use, unlimited rotation, HTTP(S) and SOCKS5, and a free move to another of our cities with the remaining time carried over.
