Illinois Mobile Proxy: Carrier SIMs in Chicago
An Illinois mobile proxy is a proxy that exits on a US carrier address geolocating to Illinois. Mobile Proxy USA provides one with an AT&T, T-Mobile or Verizon SIM in a 4G or 5G device we own in Chicago, assigned to one customer. Chicago is the third most populous US city, the centre of the Midwest, and the site of the carriers' regional gateways, so an address from our Chicago hardware resolves to Chicago or to Illinois. This page states what the address shows, why Chicago is our Illinois site, the Illinois-specific work customers do, and the plan facts.
What an Illinois address shows
A lookup on a Chicago line returns AS20057 for AT&T, AS21928 for T-Mobile or AS22394 for Verizon, the carrier as the organisation, a cellular connection type and Illinois as the region. T-Mobile addresses resolve to Chicago or a nearby suburb most consistently; AT&T addresses resolve to Chicago; Verizon addresses can resolve to another Midwestern city for a time. State and country are reliable on all three, and Chicago is the second-largest US advertising market after New York, so a Chicago address is also a strong general US vantage point.
Why Chicago
Chicago has the population, the carrier infrastructure and 5G from all three carriers, and it is the default Midwestern vantage point for advertisers, retailers and media. We do not run hardware in Springfield or elsewhere in the state; a Chicago address resolves as Illinois for every state-level purpose. The line's clock is Central time, one hour behind the East Coast, which suits buyers in Europe and Africa about as well as New York does.
Illinois-specific work
Illinois has its own biometric privacy law, which changes how some sites and apps behave for Illinois residents, its own insurance and lending rules, and a retail and logistics market that national sites localise to Chicago. Customers use Chicago lines to verify Midwest-targeted advertising and local search results, to see the consent notices and features an Illinois resident is shown, to research insurance, rate and rent figures as an Illinois resident, to test Illinois-specific forms, and to operate accounts registered to Illinois businesses from an Illinois address on a Central clock. Agencies with permission to manage local profiles for Chicago-area businesses keep those sessions on a Chicago line.
The plan
One SIM in one device, chosen at checkout from USB modems, cellular routers and Android phones, for one customer. HTTP(S) and SOCKS5 with UDP over SOCKS5, VLESS on server-based lines, unlimited data, unlimited rotation by link, API, dashboard, timer or by hand, and sticky addresses for as long as the carrier holds them. 4G lines usually run 20 to 45 Mbps, 5G 50 Mbps and up. Moves to or from our other seven cities are free and keep the remaining time. Activation is immediate; support is human, 24 hours a day, by email and Telegram bot.
