T-Mobile Lines from the Chicago Rack

A T-Mobile line from Chicago Proxies is a single T-Mobile SIM in a single device that we own and keep in our Chicago rack. It is yours alone while your plan runs. Below is what you should know before picking T-Mobile over AT&T or Verizon: how the address presents to a site, how the network behaves when you rotate, what hardware we run it on, and where stock stands.

What a website sees

Our T-Mobile addresses resolve to T-Mobile USA, autonomous system AS21928. Lookup services classify the address as mobile or cellular, place it in the United States and in Illinois, and usually name Chicago as the city. T-Mobile's address blocks are allocated across its regions in a way that occasionally makes a lookup name a different Midwest city for a few minutes after a rotation, while the database catches up; it settles, and the state is never wrong. There is no hosting provider, no data centre and no VPN marker anywhere in the record, because there is none in reality.

Like every US mobile carrier, T-Mobile uses carrier-grade NAT, so the public address on your line is at that moment also the public address of a number of ordinary T-Mobile phones in the Chicago area. That shared quality is what gives the address its standing with websites, and it is also why the address is not yours to keep: T-Mobile can rotate the gateway side whenever it likes, and the same address can turn up again after you ask for a new one.

4G and 5G in our Chicago rack

T-Mobile's 5G footprint in Chicago is broad, and our rack is in a spot where its mid-band signal is strong, so the T-Mobile 5G lines are often the fastest in the building, comfortably above the 50 Mbps we quote for 5G. The 4G LTE T-Mobile devices sit in the usual 20 to 45 Mbps band. We run T-Mobile in USB modems, in cellular routers and in Android phones; the phones and routers are where most of the 5G lives, and the modems carry the 4G plans.

Pricing is the same as the other two carriers: $2 for the first two hours on 4G or $3 on 5G, then $5 or $6 for a day, $28 or $31 for a week, $65 or $75 for a month. Hours you pay for count toward the day plan if you decide to keep going. If speed is the reason you are choosing T-Mobile, take the 5G plan; if you want the Chicago address and the rotation behaviour, the 4G plan does the same job for less.

How rotation behaves on T-Mobile

T-Mobile's Chicago gateway tends to hand out a different address on each reconnect more readily than AT&T's does, which is why customers who need many distinct addresses in a session often end up on T-Mobile. The address stays with you while the data session is up, so by default the line is sticky; a new address arrives only when you ask for one through the dashboard, the rotation link, the API or a timer. Reconnects on T-Mobile hardware are quick, usually in the tens of seconds, and on the phones and routers the line comes back with its 5G attachment intact.

The honest caveat: pools are shared and finite everywhere, so repeats still happen on T-Mobile, just less often in our experience here. T-Mobile also runs its own session management, and a line that has been up for a very long time may be given a new address by the carrier without you asking. If an unrequested change would hurt what you are doing, set your own timer so that changes happen on your schedule rather than the carrier's, or consider Verizon, which holds sessions longer.

Who picks T-Mobile

Three groups mostly. People running work that needs a fresh address often, such as checking how a page or an ad serves to many different visitors, like the way T-Mobile's pool turns over. People who care about speed, such as teams pushing media uploads or running several browser profiles through one line, pick T-Mobile 5G because it is the quickest radio in our rack on most days. And people whose target apps are themselves heavy on T-Mobile's customer base, which in Chicago is a large share of younger and prepaid users, like the fit.

It is a poorer fit if you need a single address to sit still for days with the fewest possible carrier-side changes; that is Verizon's strength. And if the exact city label matters above everything, AT&T's Chicago labelling is the most consistent of the three. We would rather tell you that here than have you discover it on a paid day.

Stock, plainly

T-Mobile is usually our deepest 5G stock in Chicago and our 4G T-Mobile modems are also well supplied, but demand moves and we do sell out, most often on 5G phones toward the end of the month. The checkout lists only lines that are free this minute, so if a T-Mobile option is visible it is yours the moment payment clears. If T-Mobile is sold out, start on AT&T or Verizon and move over from the dashboard when a T-Mobile line frees up; the move is free and keeps your remaining time.

Every line, whichever carrier, comes with HTTP(S) and SOCKS5 access including UDP, unlimited data for proxy work, free moves between our US cities, rotation by dashboard, link, API or timer, and 24/7 human support by email and through the Telegram bot.
