BELLEVUE, Wash.–(BUSINESS WIRE)–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 Note 9 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 Note 9 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. Once other
wireless providers implement STIR/SHAKEN, Caller Verified will work on
calls made across networks.
