In almost 2 years of providing free scam protection, T-Mobile and Metro by T-Mobile have alerted customers to over 10 billion Scam Likely calls. Now, the Un-carrier is expanding its industry-first Caller Verified feature, using STIR/SHAKEN standards, to seven more smartphones.

Por qué es importante:

Tax Season is especially rife with scammers looking to trick innocent consumers with fake IRS calls.

Para quiénes es importante:

Anyone who is tired of the growing number of scam calls.


  T-Mobile (NASDAQ: TMUS) has your back in the ever-increasing battle against scam calls. Since launching free scam protection two years ago, the Un-carrier has alerted customers to over 10 billion Scam Likely calls. In addition, T-Mobile is expanding Caller Verified, T-Mobile’s implementation of STIR/SHAKEN standards, to seven more devices. It’s live today on the Samsung Galaxy S9 and S9+ and coming soon to the new Samsung Galaxy S10e, Galaxy S10 and Galaxy S10+, as well as LG G8 ThinQ and LG Aristo 3. T-Mobile was first in the wireless industry to implement STIR/SHAKEN when it launched Caller Verified on the Samsung Galaxy Note9 in January.

Scammers aren’t slowing down. So far in 2019, the Un-carrier has detected and notified customers of 225 million Scam Likely calls per week! And it’s anticipated that by the end of the year, nearly 50% of US mobile calls will be scams. During Tax Season – now through April 15 – scammers get even more aggressive, using number-spoofing technology to mimic a known IRS number and leaving “urgent” callback voicemails via robocalls. According to the IRS, consumers have lost over $63 million from phone scams since 2013. T-Mobile and Metro by T-Mobile help protect customers from this type of number-spoofing with network-level technology that identifies and stops spoofed IRS calls before they reach the customer.

"Scam calls are an industry-wide problem, and it seems like we're the only ones taking this threat seriously," said John Legere, CEO of T-Mobile. "The other guys make customers do the work to stay safe from scammers. If AT&T or Verizon customers want scam protection, they've gotta download an app, which only protects them as well as the last app update. We're fighting scammers at the network level, and we update our defenses every 6 minutes, so T-Mobile customers are constantly protected - without having to do a single thing."

T-Mobile and Metro by T-Mobile were the first - and still the only - wireless providers to deliver free scam protection built right into the network…no app or opt-in required. As soon as a call reaches the T-Mobile network, it's analyzed, and scam calls are then tagged to warn the customer that it's 'Scam Likely.' The T-Mobile network uses an in-line database updated every 6 minutes as well as advanced spoofing detection technology not possible in an app.

Caller Verified

T-Mobile was first to announce readiness for the FCC-recommended STIR/SHAKEN standards in November and first to launch a new feature of STIR/SHAKEN called Caller Verified on the Samsung Galaxy Note9 in January. Today, T-Mobile announced that calls on the T-Mobile network to an updated Samsung Galaxy S9 or S9+ are now Called Verified, and customers will see “Caller Verified” when calls are known to be authentic and not originated by scammers. The Un-carrier also confirmed that Caller Verified is coming soon to the new Samsung Galaxy S10e, Galaxy S10 and Galaxy S10+ and the new LG G8 ThinQ and Aristo 3.

STIR/SHAKEN standards combat illegal caller ID spoofing, which occurs when scammers temporarily hijack a phone number to match the area code and 3-digit prefix making the incoming call look familiar. Una vez que otros proveedores de servicio móvil implementen las normas STIR/SHAKEN, Caller Verified funcionará en las llamadas realizadas entre redes.
