Built for Industries Where Fraud Costs the Most

T-Mobile's network signals integrates into your existing fraud platform across industries such as financial services, e-commerce, healthcare, and beyond. Contact us to learn how our signals can support your specific industry and use case.

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

T-Mobile's fraud signal bundles give your fraud and risk teams real-time, network-verified intelligence to detect threats at every stage of the customer journey — from account creation to high-value transactions. Integrate directly into your existing fraud platform.

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.
