SentraCell operates a hardware-isolated architecture. One client maps to one physical Android device on one carrier SIM. No shared pools, no subnets, no bandwidth partitioning. This page documents exactly how it works.
Every SentraCell proxy is defined by three dedicated, non-shared resources mapped to a single client.
| Layer | SentraCell (1:1:1) |
Typical Pool Provider |
|---|---|---|
| Device | One physical Android smartphone, yours alone | Each device split across many paying users at once |
| SIM / Carrier | One dedicated carrier SIM (Verizon, AT&T, or T-Mobile) | SIMs pooled or sourced via SDK partner apps |
| IP Assignment | Carrier-assigned IP exclusive to your device | One IP cycled between many customers via NAT gateway |
| Bandwidth | Unlimited, not partitioned or metered | Metered per GB, drawn from shared capacity |
| Subnet | No shared subnet partitioning | Customers share subnets and gateways |
| Network Type | Direct carrier connection, in-house managed | P2P / SDK peer network or reseller upstream |
The economics are the whole story. A pool provider's margin improves every time they put another paying customer on the same device and the same IP. So they oversubscribe: one physical device and one carrier IP get shared across many users at once, and the provider counts on customers not noticing that their "private" mobile IP is doing double, triple, or tenfold duty for strangers running their own workloads through it. When one of those strangers burns the IP (spam, fraud, aggressive scraping), everyone sharing it inherits the damage. SentraCell does the opposite: one device, one SIM, one IP, one client. There is no one else on your line, because putting someone else there is exactly the thing we do not do.
SentraCell does not emulate mobile connections or route through datacenter infrastructure dressed up as mobile. Each proxy is a physical consumer smartphone.
Every device is a consumer-grade Android smartphone running on a genuine US carrier network. The SIM card is a real postpaid or prepaid line from Verizon, AT&T, or T-Mobile. When a detection system inspects the connection, it sees a real mobile carrier ASN (AS6167 for Verizon, AS7018 for AT&T, AS21928 for T-Mobile), a carrier-assigned IP sitting on the carrier's shared NAT, and the connection fingerprint of an actual mobile device. There is no datacenter signature, no hosting-provider ASN, and no proxy-overlay artifact because there is no overlay. The device is the proxy.
Devices are housed and operated by SentraCell from US-based nodes in Texas and California. The IPs do not come from SDK partner apps that bundle proxy access into free consumer software, and they are not pulled from shared peer networks. Every device and SIM in the fleet is owned by SentraCell and assigned to a single client, so the carrier IP your device produces is yours alone for the life of your plan.
Rotation is controlled by you, not automated on a timer that breaks your sessions.
Because each device is dedicated, rotation works differently than a pool. There is no automated per-request rotation cycling you through random exit nodes. Your IP stays stable for as long as you need it, which is what account-based workflows require. When you do want a fresh IP, you control it: open your rotation link or send the rotate command to the SentraCell Telegram bot. The device briefly cycles into airplane mode, reconnects to the carrier, and comes back with a new carrier-assigned IP in around 10 seconds. Your credentials stay the same; only the exit IP changes. You get a fresh carrier IP when you ask for one, without the session instability of automated pool rotation.
SentraCell delivers credentials in a standard format that works everywhere.
Each proxy is delivered as a standard protocol://HOST:PORT:USERNAME:PASSWORD credential set, available over SOCKS5 and HTTP(S). This plugs directly into any antidetect browser (AdsPower, Multilogin, GoLogin, Dolphin Anty), any automation framework (Puppeteer, Playwright, Selenium), and any tool or script that accepts standard proxy input. For full code examples, see the integration guide.
