T-Mobile Mobile Proxies, City by City

T-Mobile is the carrier on our menu that rotates most eagerly. Ask for a new address and you almost always get one, which makes it the natural choice for research that wants many identities in a day. It also has a habit of being labelled at state level rather than metro level in geolocation databases, which matters for some jobs and not at all for others. This page lays out how T-Mobile behaves in each of our eight cities and how to decide whether it is your carrier.

What a site sees from a T-Mobile line

A T-Mobile line hands a site an address registered to T-Mobile USA, autonomous system AS21928, flagged as mobile by the geolocation and fraud vendors. The location field reads the state reliably and the metro often, but T-Mobile's pools are registered more coarsely than the other two carriers, so a state-only read is common. The address is shared with ordinary T-Mobile phones behind carrier NAT; what is yours alone is the SIM, the device and their history for the term.

T-Mobile also carries a lot of IPv6 traffic natively. Our lines present a normal IPv4 address to sites, so nothing changes for you, but it is one reason T-Mobile's IPv4 pools behave the way they do.

T-Mobile's pools are also the ones that attract the most lookups from fraud checkers, simply because the carrier is popular with people who use phones for work. That means a T-Mobile address can occasionally carry a louder history than the same city's Verizon address, and it is why we tell customers to read a checker's flags rather than its number. The mobile flag is always there; the rest is the address's past, not yours.

City-by-city behaviour

The pattern is the same everywhere: fresh addresses on rotation, state-level labelling more often than on AT&T or Verizon.

• New York: reads as New York; metro usually present. Very deep pool.
• Los Angeles: reads as California; metro present more often than not.
• Chicago: reads as Illinois, usually Chicago.
• Houston: reads as Texas; metro sometimes missing.
• Phoenix: reads as Arizona, usually Phoenix.
• Miami: reads as Florida; metro sometimes missing.
• North Carolina: reads as North Carolina; Charlotte or Raleigh when a metro is shown.
• Boston: reads as Massachusetts, usually Boston. No New York quirk on T-Mobile.

4G and 5G on T-Mobile

Invisible to a site; both are AS21928. At the device, 4G LTE typically 20–45 Mbps, 5G 50+ Mbps, depending on carrier signal at the device. T-Mobile's 5G footprint is wide, and on our shelves it is strong in all eight cities. Take the 4G day pass at $4 for accounts and browsing, 5G at $5 for heavy work.

Rotation and sticky behaviour

This is T-Mobile's strength. Rotate from the dashboard, a rotation link, the API, a timer or by hand, with no wait between rotations, and the new address is nearly always different from the last. Over a day of steady rotation the set of distinct addresses grows faster than on the other carriers. Left alone, T-Mobile holds a session for a reasonable stretch, but it is more likely than Verizon to change the address on its own, so for an account that must look settled, Verizon is the calmer pick.

If you want to see how T-Mobile rotates, buy a day pass and run a rotation loop for an hour: call the rotation link, wait for the device to reconnect, fetch a what-is-my-IP page, log the address. The list of distinct addresses grows quickly and the first repeat usually arrives well after the first hour. For account work, ignore the loop and simply let the line sit; rotate only between sessions and the line behaves like a phone that moved between towers during the day.

Who should pick T-Mobile

Research and monitoring that wants many addresses per day. Jobs where the state is what matters and the metro is a bonus. Boston, when you do not want the AT&T New York quirk and Verizon is out of stock. Anyone whose account or audience is on T-Mobile. Less ideal for a single account that must sit on one address for a long time; possible, but Verizon does that better.

T-Mobile is also the carrier we suggest when a customer wants to pair a rotating research line with a sticky account line in the same city: T-Mobile for the research, Verizon for the account, two day passes, two pools, no overlap. The two lines never share an address, so nothing the research line does can touch the account's history.

Ordering

Locations page, city, T-Mobile, 4G or 5G, term.
