Spin through T-Mobile IPs without a cooldown

T-Mobile is a favorite for fast-cycling work, and a DoubleProx line lets you lean into that. You get a physical device with a T-Mobile SIM in one of our US metros, dedicated to your account, and a rotation trigger you can fire as often as you like. Want a new address every request? Flip the line to per-request mode. Need to hold one for a twenty-minute session and then jump? Keep it sticky and call the API when you are done. No rotation caps, no forced pauses, unlimited data. Below is the practical guide to cycling T-Mobile addresses well.

The T-Mobile pool, explained quickly

T-Mobile USA announces its mobile address space as AS21928. Every public IPv4 address a T-Mobile phone uses comes from that space, shared through carrier-grade NAT across huge numbers of subscribers in a region. When our device reconnects, T-Mobile maps it to a public address drawn from the regional pool, just like it would for anyone turning airplane mode off and on.

Two consequences follow. Your exits look like everyday T-Mobile phone traffic because they are everyday T-Mobile phone traffic. And the pool has edges: across a long day you will occasionally land on an address you saw earlier. That is how carrier NAT works everywhere, and it is why we never promise a bottomless supply of addresses. What we do promise is that each rotation is a real reconnection to T-Mobile, not a shuffle through a static list.

Three ways to trigger a new T-Mobile IP

The dashboard gives every line a rotation link and API access, plus a per-request mode. Here is how teams typically wire them in when cycling T-Mobile addresses.

Mid-band 5G and rotation speed

T-Mobile built its 5G around a 2.5 GHz mid-band layer, a big reason its 5G lines are popular. Our 5G hardware joins that layer wherever the metro offers it; typical 5G throughput is above 50 Mbps depending on signal, while 4G lines usually deliver around 20 to 45 Mbps.

Rotation feels about the same on either tier because the reconnect time is driven by the carrier attach, not by raw bandwidth. If your workload is rotation-heavy but light per page, 4G is often plenty. If each session pulls heavy pages or media between rotations, 5G gives you more room. A 4G T-Mobile line costs $5 per day, $29 per week or $68 per month; 5G is $6, $34 or $79 on the same terms.

Choosing a metro for T-Mobile work

You select carrier and hardware at checkout, and T-Mobile availability shifts with stock in each of our live metros: New York, Los Angeles, Chicago, Houston, Phoenix, Miami, North Carolina and Boston. Houston is where most of our devices live, which usually makes it the quickest place to grab a free one. Boston runs on 4G LTE only, so choose another metro if 5G matters.

If a job later needs a different city, move the line yourself from the dashboard. Location moves between our US metros are free, and the credentials survive the move, so your scripts keep working while the exits shift to the new region's T-Mobile pool.

Rotate smart, not just fast

A fresh address is not a free pass. Because mobile addresses are shared by so many real people, platforms tend to weigh behavior far more than the IP itself. Hammering a site with dozens of requests per second will look strange whatever the address. Pair rotation with human-sized pacing, clean cookie handling and sensible retry logic, and use it for legitimate work such as price monitoring, ad verification, SEO rank checks, localization QA or managing accounts you are authorized to run.

If one platform seems to react to T-Mobile ranges differently from others, add an AT&T or Verizon line and alternate carriers in your rotation schedule. More carriers means more distinct pools to cycle through, and our 24/7 support team on email and Telegram can help you plan the split.
