Network Fraud Signals
Features
Comprehensive Fraud Signals
Real-Time Network Intelligence
Flexible Data Consumption
Built for Industries Where Fraud Costs the Most

Financial Services
Leading banks and fintech companies rely on T-Mobile's carrier-grade signals to stop SIM swap-driven account takeovers and reduce dependence on SMS OTP, without sacrificing the seamless experience that drives digital engagement and retention.

E-Commerce & Retail
High-volume merchants use real-time network signals to detect checkout fraud, prevent loyalty abuse from fake accounts, and reduce chargebacks without adding the verification friction that impacts customer conversion.

Gaming & Social Media
Platforms managing many accounts face bot-driven fake account creation, account takeover, and SMS pumping fraud that inflates OTP costs. T-Mobile's network fraud signals help validate phone number authenticity at signup, detect SIM swap activity before account recovery, and flag risky patterns like a new SIM paired with a new device, so you can protect your platform.
Fraud Signals Bundles
Talk to an expert
Account Verification Bundle
Provides real-time intelligence on account type, tenure, and activation status to confirm subscriber identity. Unlike device or behavioral signals, this data is verified directly from the network, making it harder to spoof at login, step-up authentication, and Know Your Customer (KYC) verification.
Account Change Verification Bundle
Tracks recent changes to account name, billing address, MSISDN, and porting status in real time. Uniquely surfaces the account-level activity that precedes most SIM swap and Account Takeover (ATO) attempts before fraudulent actions are completed.
Device SIM Verification Bundle
Delivers SIM and IMEI-level signals including activation dates, change events, and device loss/stolen status. Goes beyond account-level data to verify the physical device and SIM are consistent, a layer most fraud stacks don’t have visibility into.
Roaming Verification Bundle
Provides real-time visibility into roaming activity and call forwarding status. Uniquely helps identify cross-border fraud patterns and anomalous behavior that network-unaware fraud systems typically miss.
CRM Matching - Know Your Customer
Verifies customer name, address, and email against T-Mobile’s network for accurate identity matching. Distinct from the other bundles, this is purpose-built for onboarding and KYC workflows where confirming customer identity is the priority.
FAQs
How does T-Mobile’s Network Fraud Signals detect SIM swap fraud?
- T-Mobile’s Network Fraud Signals query our network directly to check whether a SIM card associated with a phone number has been recently changed. Because this signal comes from the carrier network itself, not from device behavior or user input, it's verified at the source and significantly harder for fraudsters to spoof. Enterprises can query this signal in real time at high-risk moments like login, password reset, or payment changes to trigger step-up authentication or block access before an account is compromised.
What types of fraud can T-Mobile's network fraud signals help prevent?
- T-Mobile’s Network Fraud Signals help enterprises address a range of fraud scenarios including account takeover (ATO) via SIM swap attacks, synthetic identity fraud at onboarding, payment and checkout fraud, unauthorized account changes, and SMS OTP bypass. Because the signals are verified at the network level, covering SIM status, device-SIM linkage, subscriber tenure, and account changes, they complement behavioral and device-based fraud tools by adding a layer of intelligence that operates independently of user input.
Do you support CAMARA APIs?
- Yes. T-Mobile supports CAMARA-standardized versions of our Network Fraud Signals, giving you access to network-verified intelligence through the open, industry-standard API specifications maintained by the CAMARA project. This makes integration more consistent and portable across carriers and platforms.
How does T-Mobile’s Network Fraud Signals integrate with my existing fraud platform?
- T-Mobile’s Network Fraud Signals are available as modular API bundles that integrate directly into your existing fraud decisioning systems, identity platforms, and risk scoring models without requiring a platform replacement. You can consume pre-configured bundles or select individual signals à la carte to fill specific gaps in your current stack. Our team works with you during onboarding to identify the right integration approach for your infrastructure.
What industries can benefit from T-Mobile’s Network Fraud Signals?
- T-Mobile’s Network Fraud Signals are used across many industries including financial services, e-commerce and retail, gaming, social media, healthcare, and insurance — any industry where mobile identity verification, account security, and fraud prevention at scale are priorities. Financial services and e-commerce see the highest impact given ATO rates and chargeback exposure, but the signals are applicable to any enterprise managing high-volume customer interactions where trust and identity verification are critical.
