T-Mobile mobile proxies on a Los Angeles line

T-Mobile's Los Angeles network is dense, fast on 5G, and treated by every site as ordinary phone traffic, which is why it's one of the three carriers we stock in our LA rack. A California Proxies T-Mobile line is one SIM in one device that nobody else touches while your plan runs. Below: what sites see, how the two speed tiers behave, how rotation plays out on T-Mobile, and the kinds of work people put on it.

The identity a site reads off a T-Mobile line

Traffic from the line exits through T-Mobile's wireless gateway and carries an address announced by AS21928, T-Mobile USA. Reputation and intelligence lookups return a mobile connection type, an ISP of T-Mobile USA, and a usage type of mobile ISP or cellular. The address is in the same ranges that T-Mobile hands to the phones on the Metro, in Hollywood, in Long Beach and across the rest of the county, so there's nothing about it that stands apart from a subscriber on the street.

T-Mobile leans on IPv6 internally and reaches the IPv4 internet through a translation layer at the carrier edge. In practice this means the public IPv4 address a site sees comes from a gateway pool serving a region, and the location attached to it reads as Los Angeles or Southern California with the state fixed as California. The more specific a database tries to be, the more it's guessing, and that's true of any mobile carrier, not just this one.

You get the same mobile reputation that makes carrier traffic hard to distinguish from a person on a phone, because it is carrier traffic from a real SIM on a real tower. We don't inject headers, we don't terminate TLS, and we don't route through anything that isn't the carrier.

LTE and 5G tiers

T-Mobile's 5G footprint in LA is wide, and the 5G hardware in our rack takes advantage of it. A 5G T-Mobile line typically gives you 50+ Mbps, which is overkill for most proxy work and welcome for anything that loads heavy media, runs headless browsers in parallel, or tests an app that pulls big assets. The LTE tier typically sits at 20–45 Mbps, more than enough for account management, verification and scraping at a human pace.

4G lines cost $5 per day, $28 per week or $65 per month. 5G lines cost $6, $31 or $75 for the same periods. Short jobs can use an hourly block: $2 for the first two hours on 4G, $3 on 5G, then the same per extra hour up to four, with no auto-renew and the hours credited toward a day plan if you extend.

How rotation works on T-Mobile

A T-Mobile data session tends to hold its public address until something ends the session: the modem re-registering, the carrier recycling the gateway, or you asking for a change. Left alone, you get a sticky address that's fine for a long work session on one account.

On demand, rotation is a button in the dashboard, a link you can call from any script or automation, an API endpoint, or a timer that re-registers the line every N minutes. Because the public address is assigned at the carrier gateway, a rotation may land you on a different address or back on one you've held before. The pool is regional and shared, and the carrier is in charge of the hand-out. There's no quota on rotations and no extra charge for them.

Who picks T-Mobile in Los Angeles

People who want the fastest consistent 5G in the city for the money, since T-Mobile's mid-band coverage in LA is strong. Social media and creator teams who manage several client accounts and want each one tied to its own carrier line rather than sharing a pool. Mobile app teams that need to reproduce a T-Mobile subscriber's experience, including carrier network behavior that no emulator shows. Anyone whose AT&T or Verizon preference is sold out on the day and who just needs a clean California mobile address.

What's in stock

T-Mobile SIMs sit in both LTE and 5G devices in the rack. Availability moves daily as plans start and end, and checkout always reflects the live count, so what you see there is what you can buy this minute. If the tier you want is empty, take another carrier, or reserve the slot and let your balance claim it when a device frees up. Switching a plan to another carrier or to one of our other US cities is a free, self-service move in the dashboard with the remaining time intact.
