T-Mobile mobile IPs, scripted end to end

If your automation fleet runs on cron, queues or orchestrators, a T-Mobile line from NeonProxies should feel like any other piece of infrastructure: a fixed endpoint, a documented control surface, and no surprises. Behind the endpoint sits a physical device, modem, router or Android phone, with a T-Mobile SIM, located in one of our US metros and dedicated to you. Rotation is an API call, data is unlimited, and the network identity is genuine T-Mobile. Below are the integration notes we would want if we were wiring it in ourselves.

Endpoint and control surface at a glance

Everything your code needs lives in the dashboard. Treat these values as secrets in your vault and inject them at runtime.

Identifying the network in health checks

T-Mobile USA's mobile space is announced from AS21928. Add that ASN to your startup health check: if a worker boots and the exit does not resolve to AS21928, the worker is not actually proxied and should refuse to run. That single assertion catches most integration bugs, such as a library ignoring proxy settings for HTTPS or a container missing its environment.

T-Mobile runs carrier-grade NAT on mobile IPv4, which means the public address is shared by many real subscribers and changes on every reattach. So the health check should assert the ASN, not a specific address. Services on the receiving side know that mobile addresses are shared and lean on behavioral signals, so your bot's pacing and session handling are what really shape how it is received.

Scheduling rotation around the pool

Rotation is a genuine reconnect to T-Mobile, which then hands the device an address from the regional pool. The pool is finite, so a long-running job will see repeats over a day; plan for it instead of assuming uniqueness. A simple approach is a sliding window: keep the last N addresses in memory, and if a rotation returns one of them and your task cares, rotate again.

For multi-step flows, keep the line sticky for the full flow and rotate only at the boundary. For flat task lists, per-request mode removes rotation logic from your code entirely. If you run several lines, a small scheduler that assigns tasks to whichever line is currently idle keeps throughput high without piling concurrent sessions onto one device.

Treat rotation failures like any other transient error. If the new address does not answer your echo probe within your timeout, retry the rotate call once, then mark the line degraded and route work elsewhere. Emit a metric for rotation latency per line; a slowly rising trend is an early hint to check the device or ping support before a job stalls.

5G on T-Mobile's mid-band

T-Mobile's 5G is anchored on 2.5 GHz mid-band spectrum. Our 5G T-Mobile devices attach to it where the metro has coverage and typically exceed 50 Mbps; 4G lines typically do 20 to 45 Mbps. Signal decides the final number. Browser automation that renders heavy pages or runs several contexts in parallel benefits most from 5G. Boston is our one LTE-only site.

Pricing: 4G T-Mobile is $5 per day, $30 per week or $68 per month; 5G is $7 per day, $35 per week or $82 per month. All plans include unlimited data, so long-running workers never trip a quota.

Where to deploy and how to move

Carrier and hardware are selected at checkout from stock in New York, Los Angeles, Chicago, Houston, Phoenix, Miami, North Carolina and Boston. Houston carries the most hardware in our network, so it is often the quickest place to land a T-Mobile device. Relocating a line to another metro is free and self-service, and because the endpoint stays fixed, you can move regions without redeploying a single worker.

Keep your automation legitimate: monitoring, QA, reporting, social scheduling for accounts you manage, price and availability checks. A proxy changes the network path; platform rules still apply. Our engineers are on email and Telegram around the clock if a job misbehaves.
