Roaming Fraud

Protect your business from the fraudulent usage of products and services outside of
your network committed with no intention of paying.

Fraudsters have Multiple Ways to Obtain Services

Fraudsters obtain SIMs (by stealing SIMs or through SIM cloning or through Subscription fraud) from CSPs home network and connect them to gain international roaming status to begin placing outgoing international calls. Once at an international location (VPMN), these SIMs are used for sending inflated traffic either to PRS lines or to other high-cost destinations. These are the key actions linked with roaming fraud:
  • SIM cards fraudulently obtained or cloned from service providers or network operators
  • Fraudsters exploit time delays in roaming scenarios to commit fraud
  • Fraudsters move between visited networks to remain below-agreed thresholds among roaming partners
  • Large amounts of traffic generated to high tariff international numbers or remote countries

The Importance Of Real-Time Detection and Action

Roaming fraud occurs when a subscriber moves from their home public mobile network to a visited public mobile network and uses services without intending to pay for them.
Fraudsters take advantage of operators’ inefficient data roaming exchanges to produce high-cost international revenue share calls through premium-rate numbers, which ultimately rely on operators and subscribers to pay for. As the process to analyze this information is time-consuming, fraudsters exploit this to make higher profits. The speed of detection and action is the key to stop roaming fraud.

The Out-Of-The-Box Solution Engineered to Fight Roaming Fraud

Delivered on-prem or in the cloud RAID Roaming fraud is a prepacked solution that evaluates traffic volume to identify high usage consumption or no or low traffic patterns in roaming related traffic.
The correlation between abnormal behaviors and the built-in hotlists of fraudsters and risky destinations detects and alerts to call collisions while roaming, providing you full coverage of your visitors and subscribers activity.

Monthly Updated Pre-Built Hotlists

Mobileum is well known internationally as an expert in the prevention, detection, and investigation of telecom fraud, in addition to its operational involvement in assisting CSPs to reduce their exposure to revenue losses and customer experience issues. This know-how made it possible to enhance Mobileum's fraud engines with prebuilt hotlists which contain over millions of numbers classified as fraudulent. These database has been proven invaluable to CSP's like an early identifier of attacks and is credited with avoiding fraud losses in the millions of dollars to CSP's and their customers. The correlation between abnormal behaviors and the built-in hotlists of fraudsters and risky destinations detects and alerts to call collisions while roaming, providing you full coverage of your visitors and subscribers activity.

Machine Learning and Real-Time Blocking

Implementing adaptive rule techniques combined with advanced machine learning and behavioral usage pattern recognition allows smarter, faster, and accurate fraud detection. Combined with RAID’s Roaming fraud module our voice firewall can sort good traffic from bad, block unwanted calls, throttle voice, data usage, keep your voice network safe, and secure from attack.
  • Leverage on AI and adaptive rule sets for fraud detection
  • Take actions on CAMEL, NON-CAMEL and Inbound roaming networks
  • Streamline subscription and predict potential travels
  • Integrate with Probes for faster, sharper and smarter detection and prevention
  • Minimize fraud losses and avoid reputational risk

Co-Engineered to Leverage Fraud and Security Contextual Analysis

Along with TAP and NRTRDE records, signaling messages can be processed in real-time to control calls, texts, data, and more. In Wangari fraud scenarios, for example, RAID can monitor a high number of SIP calls with zero durations to detect missed calls. RAID can also look at the dispersion of called numbers from a single origin and a dispersion of calls back to the same destination number too. By doing so, it is possible to detect these fraud attacks at the first attempt and take appropriate preventive measures.


Real-Time Fight Against Revenue Share Fraud in Roaming Network

This is the most challenging fraud to eliminate due to the complexity of the mobile network system and the involvement of multiple operators, usually its perpetrated by organized groups using illegal connections to bring a large volume of calls into high cost 'revenue share' service numbers, taking advantage on the roaming capabilities of SIM cards

Mobileum's Roaming fraud solution is an already pre-configured Fraud Management Application, which allows you to audit and control all roaming traffic CDRs combined with the use of near-real-time exchange of records on both voice and data, providing the detailed data required to detect complex and elusive fraud patterns quickly, allowing to reduce fraud detection time and losses typically by 90% or more.

Use a Test Call Generator for Enhancing Accuracy

Enhance the accuracy of roaming fraud detection without manual effort. Use Test Call Generator to automate calls for validating detected fraudsters by analyzing collected signaling messages and voice recordings. Apply machine learning models for performing voice biometric analysis on collected voice records for detecting the presence of bots and machines in roaming destinations

Bring your own ML Models (BYOM)

The evolution of sophisticated fraudulent techniques has increased the challenges of mitigating risk issues. CSPs are now actively employing data scientists, new tools, and advanced analytical models to quickly adapt to new methods to provide proactive risk coverage. These data scientists do not want to be solely dependent on vendors’ ML models and rather want to explore new ML models designed and developed in their own ecosystem.

Mobileum embraces this requirement and has now built a new openML engine based on microservice architecture, offering pluggable ML models with extensive support to all ML frameworks. This will enable the CSPs data scientists to plug and play their own developed machine learning models based on any external library or ML frameworks. Thus, offering Telecom organizations to be future proof, as they continue to develop new models to tackle unknown risk challenges using different tools and ML approaches.

Combat Roaming Fraud on VoLTE Networks

With the rise of LTE networks across the globe, and especially 4G and VoLTE services, the threat of LTE Roaming fraud is going to be even more prevalent. Mobileum’s Roaming Fraud solution combined with a voice firewall can help operators detect fraud occurring on various VoLTE Roaming network as well as block fraud attacks in real-time.

How Secure Is Your IoT Service From Roaming Fraud?

IoT roaming on mobile infrastructure is increasing every day. The actual roaming infrastructure is not equipped to manage the multitude of different roaming IoT devices.
We provide an alternative way of managing roaming in IoT. There is not much margin to support excessive costs and fees that are part of the current roaming infrastructure. Mobileum provides the solution to these challenges that hinder the growth of IoT fraud on CSPs.

Top 6 Threats Of Roaming Fraud

High Revenue Loss
The HPMN CSPs are hit hardest because of roaming fraud. Due to roaming and revenue share agreements in place, the HPMN CSPs are bound to pay the VPMN CSPs, while they are not able to recover this amount from the roaming customers, eventually leading to huge revenue losses.
Low Brand Value
Mobile phones are intended to allow communicating in a better and easier way. Nevertheless, when the service quality degrades and customers don’t get services as expected, it impacts the brand value of the CSPs.
Increase Disputes
Lack of security awareness makes users/subscribers prone to manipulations by fraudsters who perform Account Takeover, Wangiri fraud, etc., resulting in massive bill shocks to genuine subscribers. This increases customer issues increasing customer care calls and bill disputes.
Degraded Customer Experience
Blocking unrecognized numbers creates dangerous issues for subscribers, businesses, and service providers with legitimate calls from trusted sources going unanswered.
High Operational Cost
Investigating fraud is not only time consuming but also needs a huge task force resulting in high operational cost for operators.  This is not scalable for large CSPs.
Longer Fraud Run Time
The time required to detect the fraud is longer, mainly because of the delays in information sharing between operators. Fraudsters leverage this delay and perform maximum revenue damage in the least possible time.
