Mobile Proxy USA: A Plain Guide to Choosing the Carrier, the Metro and the Term

Mobile proxy USA is the phrase people type when they need one specific thing: an address on an American carrier network that reads as a phone, not as a server. The product behind that phrase, as we sell it, is one device with one AT&T, T-Mobile or Verizon SIM in a US city, serving one customer at a time, with unlimited data and rotation. That part is simple. The hard part is the string of choices between you and the right line: which carrier, which of eight metros, 4G or 5G, an hour or a month, HTTP or SOCKS5. This guide takes those choices in the order you meet them at checkout and gives the plain facts for each, so the line you end up with fits the job rather than being the first one in the list.

Prices by term

One price list for every city and carrier. 4G and 5G differ in speed only; data and rotation are unlimited on both.

What the product is, in six facts

Before the choices, the definitions. The IP address you work from belongs to AT&T, T-Mobile or Verizon and is announced by that carrier's network, so geolocation databases read it as a mobile connection in the city or state where the device sits. The device is a 4G or 5G USB modem, a cellular router or an Android phone with its own SIM, in a rack we own. It serves one customer at a time; there is no pool. The address changes only when you ask. Data is unlimited, with a fair-use rule against bulk file transfer that is not proxy work. And every line exposes both HTTP(S) and SOCKS5, with UDP over SOCKS5.

Everything else on this page follows from those six facts. If a provider you are comparing cannot state the equivalent six plainly, that tells you something as well.

Choosing the carrier: AT&T, T-Mobile or Verizon

The three carriers behave the same way for most jobs, because what a platform reacts to is that the address belongs to a mobile network at all. There are two reasons to prefer one. First, if the account you run has a US phone number attached, matching its carrier keeps the story consistent: a Verizon number logging in from a Verizon address is unremarkable. Second, stock. Each metro has a different mix on the shelf on a given day, and the dashboard shows what is in before you pay.

One carrier-specific quirk is worth knowing. In Boston, our Verizon addresses geolocate as Boston while our AT&T addresses geolocate as New York, because of how the two carriers route their gateways. If a Boston reading matters, order Verizon there. Everywhere else, all three carriers read as the city the device is in.

Choosing the metro

We run New York, Los Angeles, Chicago, Houston, Phoenix, Miami, Boston and North Carolina. The rule is to pick the city the account or the target is about. New York for New York accounts and for retail and advertising checks in the largest US media market. Los Angeles for social, entertainment and the West Coast. Chicago when you want a central, neutral address rather than a coastal one. Houston is our biggest rack and the place to go when you need several lines in one metro. Phoenix is a quieter Southwest geo, Miami is the bridge to Latin America and carries Florida's own retail and travel landscape, and North Carolina covers Charlotte and the Research Triangle for a residential Southeast address away from the headline cities.

If you get it wrong, it is not expensive. A plan moves between metros from the dashboard, free, with the remaining days intact, so a line can start the week in Chicago and finish it in Miami.

4G LTE or 5G

A 4G LTE line typically delivers 20 to 45 Mbps on our racks; a 5G line delivers 50 Mbps and up. For browsing, logins, form flows, search-result checks and collection at a sensible pace, 4G is enough and most customers buy it. For video, heavy pages or many parallel sessions on one address, 5G is the better buy. Both have unlimited data and unlimited rotation; the daily price differs by one dollar, so when in doubt the extra dollar is cheap insurance.

The hardware choice sits next to the network choice at checkout and is easier than it looks. The USB modem is the standard line and the right answer when you have no reason to pick otherwise. The cellular router holds the same SIM in a box built for long uptime, and suits a monitor or an account that must stay up for weeks without a hiccup. The Android phone is a real handset on the carrier network and is the pick when the work should look like a phone in every respect, including the way the device itself behaves. The price, the carrier and the city are the same for all three.

Rotation and sticky addresses

A line left alone is a sticky session. The address stays as long as the carrier keeps it, which is typically hours and frequently longer. When you want it to change, trigger a rotation from the dashboard, your rotation link, the API or a timer, as many times as you need; there is no limit and no cooldown. The replacement address comes from the same carrier in the same metro, so rotating never moves you across the country. Because the device is yours alone, no other customer can rotate it under you.

Use the sticky mode for anything with a login. A US-registered account expects to come from one phone address for hours at a stretch, and a line that changes address every few minutes looks less like a phone, not more. Use rotation for collection, verification and checks that touch many pages, where spreading the requests across fresh addresses keeps any one of them within the bounds of what a single person would do. The timer is for the second kind of work; the button and the link are for when you want to decide by hand.

Protocols: HTTP(S), SOCKS5 and UDP

Each line exposes an HTTP(S) port and a SOCKS5 port, and UDP is available over SOCKS5. Use HTTP(S) in browsers, antidetect profiles and most scrapers. Use SOCKS5 when the tool prefers it, when you need UDP, or when you want the proxy to carry traffic that is not web traffic, such as app testing on a phone. Both ports are live at the same time on the same line, so you can run a browser profile over HTTP(S) and a script over SOCKS5 without buying two lines.

The host, the two ports and the username and password are shown in the dashboard from the moment the line is live. Before you point anything important at it, load any public IP lookup through the proxy: it should show the carrier you ordered and the city you chose. If it does not, write to us before you do anything else, because a line that reads wrong is our problem to fix and not something to work around.

Pricing by term

Four terms, two networks, one price list for every city and carrier. Hourly: $2 for the first two hours on 4G, $3 on 5G, then $2 or $3 for each extra hour, up to four hours per purchase; it never auto-renews, and the hours count toward the day if you keep the line. One day: $5 on 4G, $6 on 5G. Seven days: $28 or $31, same line and address history all week. Thirty days: $65 or $75, the lowest price per day, with auto-renew optional.

The hourly plan is a test. The day is for a job with a deadline. The week is for a project. The month is for an account or a monitor you intend to keep, and it renews until you stop it. Pay by card, PayPal, crypto, Zelle or wire; the line activates the moment payment clears, and a first order that does not work for your target within 24 hours is refunded.

Support: who answers and what to ask

Support is by email or Telegram and a person replies, 24 hours a day. The questions worth asking before you buy are the ones the dashboard cannot answer for you: which carrier has the deepest stock in a city this week, whether a particular tool wants HTTP or SOCKS5, how to set the time zone in a browser profile to match the line, and whether a job you have in mind fits a single sticky address or a rotation schedule. After you buy, the same people can see the hardware your line is on, so a signal question gets a real answer rather than a script.
