T-Mobile dedicated mobile proxies: one modem, one SIM, one customer

A T-Mobile plan from Dedicated Mobile Proxies gives you a modem, router or Android phone in one of our US facilities with a T-Mobile subscriber SIM inside, assigned to you and to nobody else for the term. This page covers the T-Mobile specifics: how the address identifies itself, why T-Mobile's 5G footprint makes it the usual choice for a fast line, where we hold T-Mobile devices, how its sessions and rotations behave, and the way to run it so that it stays quiet.

The address from the outside

A lookup on a T-Mobile modem's address returns T-Mobile USA as the owner, under autonomous system AS21928, and a cellular connection type. It is the same range T-Mobile phones use for mobile data. Websites that score addresses give it the treatment they give any mobile carrier: cautious about blocking, because the same address is shared by many real subscribers behind carrier-grade NAT, and attentive to behaviour instead.

That sharing is at the address level only. The device and the SIM are yours for the term. The request history that a website builds for your session is built from your requests, because there is no second customer on the modem to contribute theirs. When you hold an address, you hold it; when you rotate, it is your decision.

Why T-Mobile is the 5G choice

T-Mobile's mid-band 5G covers more of our metros more consistently than the other two carriers' 5G, and it shows in the readings. Where a 4G line usually runs 20 to 45 Mbps, a T-Mobile 5G line runs 50 Mbps and up, often well up, in New York, Los Angeles, Chicago, Houston, Phoenix, Miami, North Carolina and Boston. For work that moves a lot of pages, video or app traffic, the 5G device at $6 a day, $31 a week or $79 a month is the one to pick. For monitoring and account work, a 4G device at $5, $28 or $69 is usually plenty.

Speed still depends on the tower and the hour. A 5G modem on a congested evening cell can read lower than a 4G modem on a quiet one. If speed is critical, start with an hourly block, $3 for the first two hours on 5G, and measure in the city you need before buying a month.

Geolocation and the metro reading

T-Mobile addresses in our metros generally geolocate to the metro or to the state in the common databases, and we have not seen the New York displacement that affects AT&T in Boston. Databases do disagree with each other and update on their own schedules, so a lookup may show a neighbouring city for a while. For anything that gates by state the reading is reliable; for anything that gates by city it is usually right and worth confirming on an hourly block first.

Sessions, rotation and the pool

T-Mobile keeps a data session open as long as the modem maintains it, so a sticky address can last a long time. A rotation request makes the modem re-register, and the gateway hands out another address from the regional pool. Pools are finite and addresses recur through the day; that is normal carrier behaviour. Rotation is unlimited on every plan, through the dashboard, your link, the API, a timer or by hand, and nobody else can trigger it on your modem because nobody else is on it.

T-Mobile's network is IPv6-first internally, but what you get from the modem is an ordinary public IPv4 address through the carrier's translation layer. HTTP(S) and SOCKS5 both work the same way, and SOCKS5 carries UDP for the apps that need it.

Running a T-Mobile line well

Give each identity its own modem and keep the browser profile's time zone and language matched to the modem's city. Keep signed-in work sticky and rotate only between batches of signed-out work. Use the dashboard's move feature to shift the device to another of our cities if your target market changes; the unused days carry over and there is no charge.
