T-Mobile introduces new network technology to protect customers from phone scams

T-Mobile has started rolling out new Scam ID and Scam Block features to customers to safeguard them from scam calls.

With Scam ID, customers are automatically alerted when an incoming call is likely a scam. When they enable Scam Block, T-Mobile will stop scam calls before they ever reach them. These free new customer protection features are powered by patent-pending T-Mobile technology built into the network. Scam blocking, therefore, works on all phones on T-Mobile’s network.

Scam calls cost people millions of dollars every year in America alone, according to T-Mobile. Phone scams come in all shapes and sizes, from the IRS scam to Medicare cons to “free” travel, credit card scams and countless others. They are typically run by fraudsters, often armed with robocalling technology enabling them to target vast numbers of people and make tens of thousands of calls a minute.

“Every year, three out of four people in the US get at least one scam call — and fraudsters cheat consumers out of more than half a billion dollars per year. It’s insane — so we had to do something to protect our customers,” says Neville Ray, Chief Technology Officer for T-Mobile. “So the T-Mobile team designed a brilliant set of patent-pending technologies — then built them directly into our network, so there’s nothing customers have to do. No hoops to jump through, no app to download.”

How it works

Every time someone calls a T-Mobile customer, as soon as that call reaches the T-Mobile network, the patent-pending technology analyzes it – in milliseconds – against an advanced global database of tens of thousands of known scammer numbers. The database is kept up-to-date in near real-time by analyzing every call that comes into the network with behavioral heuristics and intelligent scam pattern detection. When a match is found, the T-Mobile network tags the incoming call and warns the customer that it’s likely from a scammer. T-Mobile is able to analyze every call to identify and block scammers. The customer has the power to decline or block scam calls.

T-Mobile is enabling Scam ID and Scam Block on a rolling basis. The operator is part of an industry-wide effort to fight robocalling, led by Federal Communications Commission (FCC) Chairman Ajit Pai.
